  1. Team preview
    GPT-6 Luna brought Rotomwash,primarina,gholdengo2,387 tok · 8.9 s · $0.0006

    Rotom-Wash gives the best lead coverage and speed against the opposing Ground-types, while Primarina pressures the Dragons and Krookodile. Gholdengo rounds out the three by matching up well into Toxapex, Corviknight, and Gardevoir.

    Bonsai 2 27B brought Garchomp,toxapex,corviknight4,177 tok · 51.0 s

    Garchomp leads with Life Orb pressure on Dragonite and Primarina via Earthquake. Toxapex is an essential pivot against Rotom-Wash, Gholdengo, and Kingambit, with Regenerator and Damprock making it extremely tanky. Corviknight provides Defog for hazard control and its Flying/Steel typing resists a wide range of their attacks while Brave Bird threatens Dragonite and Primarina.

    Let me analyze this team preview for a Gen 9 Champions Rotomarenabssregmb format.
    
    My team: Garchomp, Toxapex, Krookodile, Gardevoir, Corviknight, Mimikyu
    
    Opponent's team: Garchomp, Dragonite, Kingambit, Gholdengo, Rotom-Wash, Primarina
    
    I need to pick 3 Pokémon that work best against this opponent.
    
    Let me think about matchups:
    
    **Garchomp (Dragon/Ground)** - My Garchomp is a mirror match. Both have Sandveil. My Garchomp has Life Orb and Swords Dance. This is a solid lead since it can pressure Dragonite, Kingambit, and Primarina with Earthquake/Stone Edge. Against their Garchomp, it's a 50/50 but I have Life Orb for extra damage.
    
    **Toxapex (Poison/Water)** - Great defensive pivot. Resists Water, Electric, Grass, Poison. Can handle Rotom-Wash, Primarina, Gholdengo (Steel/Ghost - Toxapex resists Ghost? No, Toxapex is Poison/Water. Ghost is neutral to Poison and Water. Steel is neutral to Poison, super effective against Water... wait no. Let me recheck.
    
    Toxapex: Poison/Water
    - Gholdengo (Steel/Ghost): Steel is neutral to Poison, super effective vs Water? No - Water resists Steel. So Toxapex resists Steel from Gholdengo. Ghost is neutral to both Poison and Water. So Gholdengo's moves are neutral or resisted. Good.
    - Rotom-Wash (Electric/Water): Electric is neutral to Poison, super effective vs Water? No, Water resists Electric. So Toxapex resists Electric. Water is neutral to Poison, neutral to Water. So Toxapex handles Rotom-Wash well.
    - Primarina (Water/Fairy): Water is resisted by Toxapex. Fairy is neutral to both. Good.
    - Kingambit (Dark/Steel): Dark is neutral to both. Steel is resisted by Water. Good.
    - Dragonite (Dragon/Flying): Dragon is neutral to both. Flying is neutral to both. Neutral matchup.
    - Garchomp (Dragon/Ground): Ground is super effective vs Poison, neutral to Water. So Earthquake hits hard. But Toxapex can't do much offensively.
    
    **Krookodile (Ground/Dark)** - Intimidate halves opponent's Attack. Good against physical attackers like Dragonite, Garchomp, Kingambit. Earthquake hits Dragonite, Garchomp, Primarina. Knockoff removes items. But weak to Water (Rotom-Wash, Primarina) and Fairy (Primarina).
    
    **Gardevoir (Psychic/Fairy)** - Choice Scarf gives speed boost. Can hit Dragonite (Fairy is super effective), Kingambit (Dark is... wait, Psychic is neutral to Dark, Fairy is neutral to Dark. Steel: Psychic is neutral, Fairy is resisted by Steel. So Gardevoir's Moonblast hits Kingambit at 0.5x). Hmm, not great against Kingambit. But Moonblast hits Dragonite for super effective. Psyshock hits Garchomp (Ground resists Psychic? No, Ground is neutral to Psychic. Actually wait - Psychic is neutral to Ground. Fairy is neutral to Ground. So Gardevoir's moves are neutral on Garchomp).
    
    Actually let me reconsider. Gardevoir with Choice Scarf:
    - vs Dragonite: Moonblast is 2x (Fairy > Flying). Good.
    - vs Kingambit: Moonblast is 0.5x (Fairy resisted by Steel), Psyshock is neutral. Not great.
    - vs Garchomp: Both moves are neutral.
    - vs Gholdengo: Fairy is super effective to Ghost? No, Fairy is neutral to Ghost. Psychic is neutral to both. Actually wait - Gholdengo is Steel/Ghost. Fairy resists... no, Fairy is not super effective against Steel or Ghost. Psychic is neutral to both. So Gardevoir doesn't hit Gholdengo well.
    - vs Rotom-Wash: Psychic is neutral to Electric/Water. Fairy is neutral to both. Not great.
    - vs Primarina: Fairy is resisted by Fairy (0.5x). Psychic is neutral. Not great.
    
    So Gardevoir is mainly good against Dragonite.
    
    **Corviknight (Flying/Steel)** - Defog clears hazards. Brave Bird hits Dragonite, Garchomp, Primarina. Flash Cannon hits Kingambit (Steel resisted by Steel... wait, Steel is neutral to Steel). Actually Steel is neutral to Steel. So Flash Cannon is neutral on Kingambit. But Corviknight resists a lot: Flying/Steel resists Rock, Bug, Grass, Normal, Psychic, Fairy, Ice, Dragon, Flying, Steel. That's great defensively.
    
    **Mimikyu (Ghost/Fairy)** - Disguise gives one free hit. Phantom Force hits Dragonite (Ghost is neutral to Dragon/Flying... wait, Ghost is neutral to Dragon and neutral to Flying). Play Rough hits Dragonite for super effective (Fairy > Flying). But Mimikyu is weak to Dark (Kingambit) and Steel (Kingambit, Gholdengo).
    
    Now let me think about the best 3:
    
    The opponent has a lot of physical attackers: Garchomp, Dragonite, Kingambit. They also have special attackers: Gholdengo, Rotom-Wash, Primarina.
    
    Best picks:
    1. **Garchomp** - Great lead. Can pressure most of their team with Earthquake (Dragonite, Garchomp, Primarina) and Stone Edge (Dragonite, Kingambit). Life Orb + Swords Dance is a great offensive threat. Handles Dragonite well (Ground > Flying), Garchomp (mirror but Life Orb gives edge), Primarina (Ground > Water). Weak to their... hmm, weak to Fairy (Primarina) and Ice. But as a lead it's fine.
    
    2. **Toxapex** - Excellent defensive pivot. Can handle Rotom-Wash, Primarina, Gholdengo, Kingambit. Regenerator + Damprock makes it very tanky. Toxicspikes can hurt their physical attackers. This is a must-have against this team.
    
    3. For the third slot: Krookodile vs Corviknight vs Gardevoir vs Mimikyu?
    
    - Krookodile: Intimidate helps against their physical threats. Earthquake hits Dragonite, Garchomp, Primarina. But weak to Water (Rotom-Wash, Primarina) and Fairy (Primarina).
    - Corviknight: Defog is great for clearing hazards. Brave Bird hits Dragonite, Garchomp, Primarina. Very defensive with Flying/Steel typing. Resists a lot of their moves.
    - Gardevoir: Choice Scarf speed lets it hit Dragonite before it can move. But limited coverage otherwise.
    - Mimikyu: Disguise is great but weak to Dark (Kingambit) and Steel (Gholdengo, Kingambit).
    
    I think **Corviknight** is the best third pick because:
    - Defog clears hazards (important in this format)
    - Very defensive Flying/Steel typing resists a lot of their moves
    - Brave Bird hits Dragonite, Garchomp, Primarina
    - Can pivot to handle threats
    - Unnerve lowers opponent's SpA
    
    Actually, let me reconsider. The opponent has Kingambit (Dark/Steel) which is a threat to Corviknight (Flying is super effective vs... wait no. Dark is neutral to Flying and Steel. Actually Dark is neutral to both. But Steel is resisted by... hmm. Let me think about what hits Corviknight hard:
    - Ground (Garchomp, Krookodile's Earthquake) - 2x
    - Fire - 2x
    - Electric - 2x
    
    And what Corviknight resists: Rock, Bug, Grass, Normal, Psychic, Fairy, Ice, Dragon, Flying, Steel. That's a LOT of resistances. Against this opponent:
    - Garchomp: Earthquake is super effective (Ground > Flying/Steel). But Stone Edge is resisted (Rock > Steel... wait, Rock is neutral to Steel? No, Rock is super effective vs Flying but resisted by Steel. So Rock is 1x overall on Flying/Steel). Actually for Corviknight taking hits: Garchomp's Earthquake is 2x. That's bad.
    - Dragonite: Dragon is resisted (Dragon > Steel... no wait. Dragon is neutral to Steel, resisted by... hmm. Let me think. Dragon moves vs Steel: neutral. Dragon moves vs Flying: neutral. So Dragon is neutral on Corviknight. But Dragonite's physical attacks are a concern.
    - Kingambit: Dark is neutral to both. Steel is resisted by Steel. So Kingambit hits for 0.5x with Steel moves, neutral with Dark.
    - Gholdengo: Ghost is neutral to both. Steel is resisted. Good.
    - Rotom-Wash: Electric is super effective (2x). Water is neutral. This is a concern.
    - Primarina: Water is neutral. Fairy is resisted. So Primarina hits for 0.5x with Fairy, neutral with Water.
    
    So Corviknight's main weakness here is Earthquake and Electric. But it still has great defensive utility with Defog.
    
    Alternatively, **KroThinking budget reached. Stop thinking and give your final answer now.

    GPT-6 Luna used Hydropump1,490 tok · 4.2 s · $0.0003

    Rotom-Wash’s Choice Scarf lets it move before Garchomp, and Hydro Pump is 4× effective with strong knockout potential. Its 80% accuracy is the main risk, but it’s the best immediate attack.

    Reasoning trace (80 words)
    **Calculating Hydro Pump effectiveness**
    
    I need to choose Hydro Pump because it has a high effectiveness—specifically 4x—but I'm unsure about the accuracy, which is 80%. Garchomp might outspeed and is immune to Earthquake, but Hydro Pump should likely knock it out at full health. The calculations for Rotom's Special Attack and Garchomp's Defense suggest Hydro Pump could deal around 200-240 damage at level 50, assuming I calculate the STAB and other factors correctly. I’ll go ahead and use Hydro Pump.
    Bonsai 2 27B used Earthquake2,499 tok · 26.1 s

    Earthquake is super effective on Rotom-Wash, gets STAB from Garchomp's Ground typing, and Life Orb boosts it further — this is a guaranteed knockout before Rotom-Wash can act. Speed advantage confirms I move first.

    Reasoning trace (595 words)
    Let me analyze this battle situation.
    
    My Garchomp (Dragon/Ground, Life Orb, Sandveil) is facing Rotom-Wash (Electric/Water, Levitate).
    
    Key factors:
    - Garchomp moves first (169 speed vs 95-151 range for Rotom-Wash)
    - Earthquake is super effective on Rotom-Wash (Ground > Water, but Electric resists Ground... wait, let me reconsider)
    
    Actually, let me check the type matchups:
    - Garchomp is Dragon/Ground
    - Rotom-Wash is Electric/Water
    
    Earthquake (Ground): 
    - Against Electric: neutral (Electric resists Ground? No - Electric is not weak to Ground. Let me think... Ground is super effective against Fire, Rock, Steel, Poison, and Ground. It's NOT super effective against Electric. Actually, Ground is neutral against Electric.)
    - Against Water: neutral
    
    Wait, the prompt says "super effective on rotomwash" for earthquake. Let me re-read... Yes, it says "super effective on rotomwash". Hmm, but that doesn't seem right type-wise. Ground vs Electric/Water should be neutral. Unless I'm wrong about the typing.
    
    Actually wait - let me reconsider. In Gen 9 Champions format:
    - Ground is super effective against: Fire, Rock, Steel, Poison, Ground
    - Ground is NOT super effective against Electric or Water
    - Ground is resisted by: Grass, Bug, Flying (and immune to Levitate)
    
    But the prompt explicitly states "super effective on rotomwash" for earthquake. I should trust the game data given to me. Perhaps there's something about the format or I'm misremembering. Let me just go with what the prompt says.
    
    Actually, wait. Let me re-read: "earthquake | Ground, Physical, power 100, 100% accuracy, super effective on rotomwash"
    
    Hmm, this is odd. But the game says it's super effective, so I'll trust that.
    
    Now, Garchomp with Life Orb:
    - Earthquake: 100 power, physical, super effective (3x damage multiplier)
    - With Life Orb: 1.3x additional damage
    - So total: 3 * 1.3 = 3.9x base damage
    
    Garchomp's Attack is 182. Rotom-Wash's Defense range is 114-174.
    
    Even at the high end (Def 174), Earthquake with Life Orb and STAB... wait, does Garchomp get STAB on Ground? No! Garchomp is Dragon/Ground, so Ground IS a STAB type for Garchomp. So:
    - STAB: 1.5x
    - Super effective: 3x (as stated)
    - Life Orb: 1.3x
    
    Total multiplier: 1.5 * 3 * 1.3 = 5.85x
    
    That's a massive damage number. Even with Rotom-Wash at max HP and high defense, this should be a knockout.
    
    Wait, actually I need to reconsider whether Ground is super effective on Electric/Water. Let me think again:
    - Water resists: Water, Steel, Rock, Grass (and Dragon? No)
    - Electric resists: Electric, Flying, Steel
    
    Ground vs Water: neutral
    Ground vs Electric: neutral
    
    So it should be 1x against both types, not super effective. But the prompt says "super effective on rotomwash." I'll trust the prompt's data.
    
    Actually, you know what, maybe I'm wrong. Let me just go with what the game tells me. The game says Earthquake is super effective on Rotom-Wash. Combined with STAB (Ground is one of Garchomp's types) and Life Orb, this should absolutely KO Rotom-Wash.
    
    So the best move is clearly Earthquake - it's a guaranteed knockout given the damage numbers.
    
    Let me calculate roughly:
    - Base damage: 182 * 100 / 50 = 364 (roughly)
    - STAB: *1.5 = 546
    - Super effective: *2 (or *3?) - if it's "super effective" that's typically 2x in Pokémon, not 3x. Let me use 2x.
    - Life Orb: *1.3
    
    So roughly: 364 * 1.5 * 2 * 1.3 = 1408 damage
    
    Rotom-Wash HP range: 125-157 at level 50. Even at max (157), this is a massive KO.
    
    Earthquake is the clear choice. It's super effective, STAB, and with Life Orb it will absolutely KO Rotom-Wash.

    GPT-6 Luna used Hydropump1,410 tok · 2.7 s · $0.0003

    Hydro Pump already took Garchomp to 42%, so another hit is likely to knock it out. Rotom is immune to its revealed Earthquake, making the attack worthwhile even if Garchomp moves first.

    Bonsai 2 27B switched to Corviknight3,151 tok · 39.4 s

    Earthquake was immune on Turn 1 due to Levitate, so Garchomp's main STAB is useless here. At 42% HP it's vulnerable to a follow-up Hydro Pump. Switching to Corviknight gives me a full-HP Pokémon with super-effective Brave Bird (Flying > Water) that can threaten an immediate KO.

    Reasoning trace (946 words)
    Let me analyze this situation:
    
    - My Garchomp is at 77/183 HP (42.1%) with Life Orb and Sandveil
    - Opponent's Rotom-Wash is at full HP (100%)
    - I move first (Garchomp SPE 169 vs Rotom-Wash SPE 95-151)
    
    Key considerations:
    - Garchomp already took a Hydro Pump hit (77/183 remaining). It's at about 42% HP.
    - Earthquake is super effective on Rotom-Wash (Ground > Water, but Rotom-Wash has Levitate so it's not immune to Ground... wait, actually Rotom-Wash is Electric/Water with Levitate. Ground moves hit it normally since it's not Ground-type. Wait, let me re-read: "Your Garchomp used Earthquake - Opposing Rotom was immune"
    
    Wait, that's from Turn 1! The opponent's Rotom was immune to Earthquake. That makes sense because... wait, no. Rotom-Wash is Electric/Water. Ground attacks are not super effective on Water (they're neutral). But the text says "Opposing Rotom was immune." 
    
    Hmm, actually looking at the stats: Rotom-Wash has Levitate. But Levitate only gives immunity to Ground-type moves if the Pokémon doesn't have a Ground-type... wait no. Levitate makes the Pokémon immune to Ground-type attacks regardless of its typing. So Earthquake would be immune!
    
    Wait, but the text says "Your Garchomp used Earthquake - Opposing Rotom was immune." So yes, Earthquake is useless against this Rotom-Wash because of Levitate.
    
    So my options:
    1. Swords Dance - boosts attack, but I'm at 42% HP and could get KO'd by Hydro Pump next turn
    2. Earthquake - IMMUNE (useless)
    3. Stone Edge - Rock is neutral to Water, super effective to... wait, Rotom-Wash is Electric/Water. Rock is neutral to both. So it's a neutral hit. Power 100, 80% accuracy. With Life Orb: 1.3x damage. Garchomp ATK 182. Let me estimate: at level 50, base stat 182... this would deal significant damage but probably not KO Rotom-Wash (which has unknown item and stats in range).
    4. Substitute - takes 1/4 HP (about 46 HP), leaving Garchomp at ~31 HP. That's very risky.
    5. Switch to Toxapex - safe, can set up Toxic Spikes or Recover
    6. Switch to Corviknight - safe, can Defog or Brave Bird
    
    Given that:
    - Earthquake is useless (immune)
    - Garchomp is at 42% HP and vulnerable to Hydro Pump
    - Stone Edge would deal neutral damage but might not KO
    - I should probably switch out to preserve my team
    
    Actually wait - let me reconsider. Garchomp at 77/183 HP. If it uses Stone Edge, it deals roughly: (182 * 100 / 100) * 1.3 (Life Orb) / opponent's SpD... actually this is physical so we use Def. Rotom-Wash Def range is 114-174. Let's say around 140 average. Damage would be roughly (182*100/150) * 1.3 ≈ 158 damage? That might KO a full HP Rotom-Wash with ~125-157 HP... actually it could be close to a KO or even a KO.
    
    But wait, Stone Edge has 80% accuracy. And Garchomp would lose Life Orb damage (1/10 max HP = 18 HP) after attacking. So Garchomp goes from 77 to 59 HP.
    
    Hmm, but actually the deciding factor here: Garchomp is at 42% HP and Rotom-Wash can hit it with Hydro Pump (super effective? No - Water is neutral to Dragon/Ground). Actually Water is neutral to both Dragon and Ground. So Hydro Pump would deal neutral damage.
    
    Let me think about what's best:
    - If I switch, I preserve my team but lose momentum
    - If I Stone Edge, I might KO Rotom-Wash (80% accuracy) but take a Life Orb hit
    - If I Swords Dance, I set up for next turn but risk getting KO'd
    
    Actually, the most important factor: Garchomp is at 42% HP. Rotom-Wash has Hydro Pump which is neutral to Dragon/Ground. At level 50 with stats in range, a full-power Hydro Pump from Rotom-Wash (SpA 112-172) would deal significant damage. Let's estimate: SpA ~140 average, HP of Garchomp 183. Damage ≈ (140*110/150) * (183/def)... this is getting complicated.
    
    The key insight: Earthquake was immune in Turn 1, so I can't use it. Stone Edge is my best offensive option but has 80% accuracy and Garchomp is already hurt. 
    
    I think the safest and most strategic play is to switch out. Garchomp is at 42% HP and its main STAB (Earthquake) is useless against this Levitate Rotom-Wash. I should bring in a fresh Pokémon.
    
    Between Toxapex and Corviknight:
    - Toxapex: Can set Toxic Spikes, Recover, Sludge Bomb (neutral to Electric/Water... actually Poison is neutral to both). Very defensive.
    - Corviknight: Brave Bird is super effective on Water! Flying > Water. This could be a great KO threat.
    
    Corviknight's Brave Bird: Power 120, Flying type, super effective on Water. ATK 107. Against Rotom-Wash (Def 114-174). This would likely KO or nearly KO Rotom-Wash. And Corviknight is at full HP.
    
    Actually, let me reconsider Stone Edge. Garchomp ATK 182, Stone Edge power 100, Life Orb 1.3x. Against Rotom-Wash Def (let's say ~140): Damage ≈ (182 * 100 / 150) * 1.3 ≈ 157. Rotom-Wash HP range is 125-157. So Stone Edge could KO if HP is on the lower end, but might not if it's higher. And 80% accuracy means 20% chance of missing.
    
    I think switching to Corviknight is the best play. It gives me a super effective Brave Bird that can likely KO Rotom-Wash, and I'm at full HP. The deciding factor is the bad matchup (Earthquake immune) forcing a switch, and Corviknight's Flying-type STAB being super effective on Water.
    
    Wait, but actually - should I just Stone Edge now? If it hits, it might KO. But 80% accuracy... and Garchomp drops to ~59 HP after Life Orb drain. Then next turn Rotom-Wash could hit with Hydro Pump.
    
    I'll go with switching to Corviknight for the super effective Brave Bird threat.
    
  4. Turn 3
    GPT-6 Luna switched to Gholdengo1,581 tok · 4.6 s · $0.0003

    Rotom is Choice-locked into Hydro Pump, and Corviknight can comfortably heal off a hit with Leftovers. Gholdengo is the better matchup, resisting Flying and Steel while being immune to Fighting.

    Reasoning trace (81 words)
    **Analyzing battle strategy**
    
    I need to make a decision. Corviknight is at 58%, and I'm considering if Rotom is locked into Hydro Pump. If it is, then I might have to switch due to being Choice Locked. Switching to Gholdengo seems favorable since it resists Corviknight's Flying type moves. I wonder about potential damage; hitting Corviknight with Hydro Pump could deal around 30-40% damage, but switching to Gholdengo might be the best option here. It's important to assess this matchup carefully.
    Bonsai 2 27B switched to Toxapex3,657 tok · 52.6 s

    Rotom-Wash moves first and its Hydro Pump is the main threat. Switching to Garchomp would be catastrophic (Water is 2x on Ground), and Corviknight's attacks are all poorly effective here. Toxapex at full HP resists Hydro Pump (0.5x Water/Water + Damprock) and can stall with Protect or Recover, making it the clear defensive pivot.

    Reasoning trace (1,163 words)
    Let me analyze this situation carefully.
    
    My active Pokémon is Corviknight at 103/175 HP (58.9%). The opponent has Rotom-Wash at 100% HP.
    
    Key considerations:
    - Rotom-Wash moves first (speed 95-151 vs my 87)
    - Rotom-Wash is Electric/Water, so it's immune to Ground (which is why Earthquake didn't work on Garchomp earlier... wait, no, that was a different situation)
    - Actually, Rotom-Wash has Levitate, so it's immune to Ground moves. That's why my Garchomp's Earthquake did nothing.
    
    Wait, let me re-read. The opponent is Rotom-Wash with Levitate. So:
    - Ground moves are useless against it
    - Electric moves are useless (same type)
    - Water moves are not very effective (4x resist? No, Water resists Water 0.5x)
    - Steel is 1/4x weak to... wait, Rotom-Wash is Electric/Water. Steel is neutral to Electric and neutral to Water. So Flash Cannon would be neutral, not 1/4x.
    
    Wait, the legal actions say "Flashcannon | Steel, Special, power 80, 100% accuracy, 1/4x on rotomwash". That's odd. Let me think... Actually wait, maybe I'm wrong about the typing. Rotom-Wash is Electric/Water. Steel vs Water: neutral. Steel vs Electric: neutral. So it should be neutral. But the game says 1/4x. Hmm, maybe there's something else going on. Let me just trust the game data.
    
    Actually wait - looking more carefully at the legal actions:
    - Bravebird: "not very effective on rotomwash" - Flying vs Electric/Water is neutral... unless there's some other factor. Actually, Water resists Flying 0.5x? No, that's not right either. Let me think... Flying is neutral to Electric and neutral to Water. So it should be neutral. But the game says "not very effective." Maybe I'm wrong about the typing interaction.
    
    Actually, I'll just trust what the game tells me. The game says:
    - Bravebird: not very effective (0.5x)
    - Flashcannon: 1/4x on rotomwash
    
    Hmm, that's strange for both. But let me go with it.
    
    Wait, actually maybe I should reconsider. In Gen 9 Champions format, could there be some other factor? No, I think the game is just telling me the effectiveness. Let me trust it.
    
    So my options:
    1. Bravebird - not very effective (0.5x), 33% recoil. With Corviknight at 107 ATK and Rotom-Wash at ~125-157 HP... this would deal limited damage and hurt myself.
    2. Flashcannon - 1/4x, so basically useless damage.
    3. Defog - clears hazards (none currently), but also lowers evasion by 1. Not very useful here.
    4. Roost - heals 50% HP, removes Flying type. This would heal Corviknight to ~175/175 (since it's at 103, healing 50% of max = 87.5, so 103 + 87 = 190... capped at 175). But removes Flying type, making it Steel only.
    5. Switch to Toxapex - full HP, Poison/Water, very defensive
    6. Switch to Garchomp - at 42% HP, Dragon/Ground
    
    Key strategic considerations:
    - Rotom-Wash moves first and has Hydro Pump (110 BP Water). Against Corviknight (Flying/Steel), Water is not very effective (0.5x) because Steel resists Water. So Hydro Pump would deal reduced damage to Corviknight.
    - But wait, Corviknight already took a Hydro Pump and went from 175 to 93 (82 HP lost), then healed with Leftovers to 103. Let me check: 175 - 82 = 93, + 11 (Leftovers) = 104... close enough to 103. So Hydro Pump dealt about 82 damage to Corviknight at full HP. That's already reduced by the Steel resistance.
    
    Actually wait, looking at turn 1: Garchomp took Hydro Pump and went from 183 to 77 (106 HP lost). Turn 2: Corviknight took Hydro Pump and went from 175 to 93 (82 HP lost), then healed to 103.
    
    So Rotom-Wash's Hydro Pump is dealing significant damage even with resistances.
    
    Now, what should I do?
    
    Option A: Switch to Toxapex
    - Toxapex is Poison/Water at full HP
    - Poison resists... Water is neutral to Poison. So Hydro Pump would be neutral on Toxapex.
    - But Toxapex has Regenerator and Damprock (20% damage reduction)
    - Toxapex's SpD is 194, which is very high
    - This seems like a solid defensive switch
    
    Option B: Switch to Garchomp
    - Garchomp is Dragon/Ground at 42% HP
    - Ground is immune to... wait, Rotom-Wash has Levitate so it's immune to Ground. But what about Hydro Pump? Water vs Dragon/Ground: Water is neutral to Dragon and super effective on Ground (2x). So Hydro Pump would be 2x on Garchomp! That's terrible.
    - Actually wait, let me reconsider. Water vs Ground: yes, Water is super effective on Ground (2x). And Water vs Dragon: neutral. So overall it's 2x.
    - Garchomp at 42% HP taking a 2x Hydro Pump would likely be KO'd.
    - This is a bad switch.
    
    Option C: Roost
    - Heals Corviknight to full HP (175)
    - Removes Flying type, leaving Steel only
    - Rotom-Wash's Hydro Pump on Steel-only Corviknight: Water vs Steel = 0.5x. Same as before actually since it was already Steel-resisting.
    - But now Corviknight can't use Bravebird next turn (no Flying type)
    - This is a recovery option but doesn't solve the problem of what to do with Rotom-Wash
    
    Option D: Flashcannon
    - 1/4x effectiveness means basically no damage
    - Not useful
    
    Option E: Bravebird
    - 0.5x, 33% recoil
    - Won't deal meaningful damage
    - Self-damage makes it worse
    
    Option F: Defog
    - No hazards to clear
    - Lowers evasion by 1 (bad)
    - Not useful
    
    So the best options are switching to Toxapex or Roosting.
    
    Let me think about Toxapex more carefully:
    - Toxapex is Poison/Water at full HP with Damprock and Regenerator
    - Hydro Pump on Toxapex: Water vs Poison = neutral, Water vs Water = 0.5x. So it's 0.5x!
    - Wait, that's right. Water is not very effective on Water types. And Poison resists... actually let me think again.
    - Water move on Poison/Water target: Water vs Poison = neutral (1x), Water vs Water = 0.5x. Combined: 0.5x.
    - So Hydro Pump would be halved on Toxapex!
    - Plus Damprock reduces damage by 20%
    - Plus SpD of 194 is very high
    
    This makes Toxapex an excellent defensive pivot against Rotom-Wash's Hydro Pump.
    
    Also, Toxapex can use Sludgebomb (Poison/Special) which would be neutral on Electric/Water... actually Poison vs Water: neutral. Poison vs Electric: neutral. So it's neutral. But with 65 SpA, it won't deal much damage.
    
    Toxapex could also set up Toxic Spikes or use Protect.
    
    I think switching to Toxapex is the best move here. It's a full-HP defensive pivot that resists Rotom-Wash's main attack (Hydro Pump) and can stall out the opponent while I look for better options.
    
    Actually, let me reconsider Roost. If I Roost:
    - Corviknight heals to 175/175
    - Loses Flying type
    - Next turn, Rotom-Wash moves first with Hydro Pump (0.5x on Steel)
    - Then Corviknight can use Flashcannon (1/4x... basically useless) or Defog
    - This doesn't really solve the problem
    
    Switching to Toxapex is clearly better because:
    1. Full HP
    2. Resists Hydro Pump (0.5x + Damprock 20% = very low damage)
    3. Can stall with Protect, Recover, or Toxic Spikes
    4. Regenerator provides additional recovery
    
    I'll go with SWITCH: toxapex.

    Gholdengo is faster, and Good as Gold blocks Toxapex’s status moves, making this a favorable setup opportunity. Nasty Plot can punish a switch and turn Gholdengo into a major threat.

    Reasoning trace (74 words)
    **Analyzing strategy options**
    
    I’m considering the potential of a nasty plot and how to choose the right legal string. Speed is a decisive factor, especially since Gholdengo is faster. I need to weigh the setup versus the switch. However, Toxapex can’t apply status effects, which might be a stumbling block because it’s resilient. Still, I should explore possible attack options to navigate this situation effectively. Let's see how I can strategize around these factors!
    Bonsai 2 27B switched to Corviknight3,734 tok · 49.1 s

    Gholdengo moves first with likely Bolt Beam or Iron Head, both resisted by Corviknight's Flying/Steel typing. Switching to Corviknight gives a safe pivot that resists Gholdengo's main threats while preserving Toxapex for later.

    Reasoning trace (1,201 words)
    Let me analyze this situation carefully.
    
    My active Pokémon is Toxapex at 100% HP with Damprock and Regenerator. The opponent's active is Gholdengo at 100% HP with GoodasGold (immune to status moves).
    
    Key considerations:
    - Gholdengo is Steel/Ghost, so it's immune to Poison-type moves (Sludgebomb won't work - confirmed in the legal actions)
    - Gholdengo has GoodasGold, so it's immune to status moves. This means Toxicspikes and Protect... wait, Protect is a move, not a status effect on the opponent. But Toxicspikes sets up a trap that affects grounded foes. Gholdengo is Steel/Ghost - Ghost types are immune to Ground-type attacks but can be hit by most things. However, GoodasGold makes it immune to status moves. Does Toxicspikes count as a status move? Yes, it's a Status move. So Toxicspikes would be blocked by GoodasGold.
    
    Wait, let me reconsider. GoodasGold: "This Pokemon is immune to Status moves." This means Gholdengo cannot be affected by status moves. So:
    - Sludgebomb: No effect (immune to Poison) AND it's a special attack, not a status move. But the legal actions say "no effect on gholdengo" - this is because of Poison immunity.
    - Recover: Status move on itself, should work fine
    - Toxicspikes: Status move, would be blocked by GoodasGold
    - Protect: Status move with priority, but it's a defensive move on itself... actually, does GoodasGold block Protect? No, Protect is used BY the user. GoodasGold makes Gholdengo immune to status moves directed AT it. So Protect should work fine.
    
    Wait, but actually let me reconsider Toxicspikes. The legal actions say "Poisons grounded foes on switch-in." Gholdengo is Steel/Ghost - it's not a Ghost type that floats... wait, Ghost types are immune to Ground-type attacks but they can be hit by most things. Actually, in Gen 9 Champions, Ghost types CAN be affected by Toxicspikes because they're not "grounded" in the traditional sense? No wait - Toxicspikes affects "grounded foes." Ghost types are considered grounded for hazard purposes (they don't have Levitate or similar). But Gholdengo is Steel/Ghost, and it doesn't have Levitate. So it would be affected by Toxicspikes if it switches in... but GoodasGold makes it immune to status moves, so the Toxicspikes move itself would fail.
    
    Actually wait - I need to re-read GoodasGold. "This Pokemon is immune to Status moves." This means any status move directed at Gholdengo will have no effect. So Toxicspikes (a status move) would be blocked.
    
    So my options are:
    1. Sludgebomb - no effect (Poison immunity)
    2. Recover - heals 50% of max HP, but I'm already at 100%, so this is wasted
    3. Toxicspikes - blocked by GoodasGold
    4. Protect - priority +4, prevents damage this turn
    5. Switch to Corviknight (58.9% HP)
    6. Switch to Garchomp (42.1% HP)
    
    Gholdengo is Steel/Ghost. Let me think about what it can do:
    - It's a special attacker (SpA 137-203)
    - It moves first (speed 93-149 vs Toxapex 55)
    - GoodasGold means it's immune to status moves
    
    What are Gholdengo's likely moves? In Gen 9 Champions, Gholdengo typically runs:
    - Bolt Beam (Electric/Special, BP 120)
    - Iron Head (Steel/Physical, BP 80)
    - Shadow Ball (Ghost/Special, BP 100)
    - Flash Cannon (Steel/Special, BP 80)
    - or maybe something else
    
    Gholdengo is Steel/Ghost. Toxapex is Poison/Water:
    - Toxapex resists Water (4x? No, Water is neutral to Poison... wait)
    - Actually let me think about type matchups:
      - Gholdengo's likely moves: Bolt Beam (Electric), Iron Head (Steel), Shadow Ball (Ghost), Flash Cannon (Steel)
      - Toxapex (Poison/Water): 
        - Electric: Neutral to Water, resists... no. Electric is neutral to Poison and neutral to Water. So Electric is neutral.
        - Steel: Resisted by Water (4x? No). Water resists Steel? No. Let me think... Steel is resisted by Fire, Fighting, Ground. Water doesn't resist Steel. Actually, Steel attacks on Water types are neutral. On Poison types, Steel is neutral. So Steel is neutral to Toxapex.
        - Ghost: Neutral to both Poison and Water.
        
    Wait, actually let me reconsider. Gholdengo's moves in Gen 9 Champions:
    - Bolt Beam (Electric/Special)
    - Iron Head (Steel/Physical)  
    - Shadow Ball (Ghost/Special)
    - Flash Cannon (Steel/Special)
    
    Toxapex takes:
    - Electric: Neutral (Poison resists... no, Poison doesn't resist Electric. Water is neutral to Electric.) So Electric is neutral.
    - Steel: Neutral to both types.
    - Ghost: Neutral to both types.
    
    So Toxapex doesn't have great resistance to Gholdengo's likely moves. However, Toxapex has very high SpD (194) and Def (224), so it can tank hits.
    
    But the key issue is: Gholdengo moves first and will hit with a super effective or neutral move. Let me think about what's most threatening.
    
    Actually, wait. Let me reconsider. In Gen 9 Champions format, Gholdengo typically runs:
    - Bolt Beam (120 BP Electric Special)
    - Iron Head (80 BP Steel Physical)  
    - Shadow Ball (100 BP Ghost Special)
    - Flash Cannon (80 BP Steel Special)
    
    Or maybe it runs something like:
    - Bolt Beam
    - Iron Head
    - Shadow Ball
    - Protect or Roost or something
    
    Given Gholdengo's stats (SpA 137-203), it's a special attacker. Bolt Beam at 120 BP would be very threatening.
    
    Now, what should I do?
    
    Option: Switch to Corviknight
    - Corviknight is Flying/Steel
    - Gholdengo is Steel/Ghost
    - Gholdengo's moves vs Corviknight:
      - Bolt Beam (Electric): Neutral to Flying, resists... no. Electric is neutral to Flying and neutral to Steel. So neutral.
      - Iron Head (Steel): Resisted by Flying? No. Steel is resisted by Fire, Fighting, Ground. Flying doesn't resist Steel. Actually wait - Steel attacks on Steel types are super effective? No! Steel is not super effective against Steel. Let me think again.
      
      Type chart:
      - Steel resists: Normal, Grass, Ice, Bug, Rock, Dragon, Fairy, Steel (8x resistances)
      - Steel is weak to: Fire, Fighting, Ground
      
      So Iron Head (Steel) on Corviknight (Flying/Steel): Steel is resisted by Steel (4x resist? No, it's a single type resist). Actually, Steel resists Steel at 0.5x. And Flying doesn't interact with Steel. So Iron Head would be super effective... no wait.
      
      Let me redo this:
      - Steel attack on Flying/Steel target:
        - Steel vs Flying: Neutral (1x)
        - Steel vs Steel: Resisted (0.5x)
        - Combined: 0.5x = resisted
      
      So Iron Head would be resisted by Corviknight! That's good.
      
      - Bolt Beam (Electric) on Corviknight:
        - Electric vs Flying: Neutral
        - Electric vs Steel: Resisted (0.5x)
        - Combined: 0.5x = resisted
      
      - Shadow Ball (Ghost) on Corviknight:
        - Ghost vs Flying: Neutral
        - Ghost vs Steel: Neutral
        - Combined: 1x = neutral
    
    So Corviknight resists Bolt Beam and Iron Head, and takes neutral from Shadow Ball. That's actually a good matchup!
    
    But wait - Gholdengo is Steel/Ghost. Does it have any super effective moves against Corviknight?
    - Ghost moves on Flying/Steel: Neutral
    - Electric moves on Flying/Steel: Resisted (0.5x)
    - Steel moves on Flying/Steel: Resisted (0.5x)
    
    So Gholdengo doesn't have anything super effective on Corviknight. That's great!
    
    Now what about Garchomp?
    - Garchomp is Dragon/Ground
    - Gholdengo's moves vs Garchomp:
      - Bolt Beam (Electric): Electric vs Dragon = Neutral, Electric vs Ground = Immune! So Bolt Beam would be immune to Garchomp.
      - Iron Head (Steel): Steel vs Dragon = Resisted (0.5x), Steel vs Ground = Super effective (2x). Combined: 1x = neutral.

    Shadow Ball is the strongest hit into Corviknight: Make It Rain is resisted, while Shadow Ball is neutral and gets STAB. Gholdengo moves first, and at +2 it has a strong chance to knock Corviknight out before it can respond.

    Bonsai 2 27B switched to Toxapex3,818 tok · 49.5 s

    Gholdengo has +2 SpA and moves first, making it a serious special threat to Corviknight's 137 SpD. Both Brave Bird and Flash Cannon are not very effective on Steel/Ghost, so attacking is poor. Switching to Toxapex (194 SpD, Regenerator) safely absorbs the hit while preserving Garchomp for later.

    Reasoning trace (1,078 words)
    Let me analyze this situation carefully.
    
    Current state:
    - My active: Corviknight (Flying/Steel) at 113/175 HP, with Unnerve and Leftovers
    - Opponent's active: Gholdengo (Steel/Ghost) at 100% HP, with +2 SpA from Nasty Plot, GoodasGold ability
    
    Key considerations:
    - Gholdengo has +2 SpA boost. It's a Steel/Ghost type.
    - Corviknight is Flying/Steel - it resists Ghost (4x? No, Steel resists Ghost... wait no. Let me think about this properly.)
    
    Actually, let me reconsider the type matchups:
    - Gholdengo is Steel/Ghost
    - Corviknight is Flying/Steel
    
    Gholdengo's likely moves: It used Nasty Plot. With +2 SpA, it probably has a strong special move. Given it's Steel/Ghost, it could have Shadow Ball (Ghost), Sludge Bomb (Poison - super effective on Steel? No...), or maybe something else. Actually, looking at the revealed moves, only Nasty Plot is revealed. But with +2 SpA, it's clearly a special attacker.
    
    Wait, let me reconsider. Gholdengo is Steel/Ghost. Its weaknesses:
    - Ground (4x) - but Gholdengo doesn't have Levitate... wait, actually Gholdengo does NOT have Levitate. It has GoodasGold. So Ground would be 4x effective.
    - Actually wait, let me recheck. Gholdengo is Steel/Ghost. 
      - Steel weaknesses: Fire (2x), Fighting (2x), Ground (2x)
      - Ghost weaknesses: Dark (2x), Ghost (2x)
      - Combined: Ground is 4x (Steel x2, Ghost... wait no. Ghost doesn't have a weakness to Ground. Let me redo this.
    
    Gholdengo type matchups:
    - Steel: Weak to Fire(2x), Fighting(2x), Ground(2x). Resists Normal(0.5x), Flying(0.5x), Grass(0.5x), Ice(0.5x), Poison(0.5x), Psychic(0.5x), Bug(0.5x), Rock(0.5x), Dragon(0.5x), Fairy(0.5x). Immune to Poison, Steel, Ground? No wait...
    
    Actually let me be more careful:
    - Steel type: Weak to Fire(2x), Fighting(2x), Ground(2x). Resists Normal(0.5x), Flying(0.5x), Grass(0.5x), Ice(0.5x), Poison(0.5x), Psychic(0.5x), Bug(0.5x), Rock(0.5x), Dragon(0.5x), Fairy(0.5x). Immune to Poison, Steel, Ground? No - Steel is immune to Poison and Steel moves. Not Ground.
    
    Wait, I'm confusing myself. Let me just focus on what matters:
    
    Corviknight (Flying/Steel) vs Gholdengo (Steel/Ghost):
    - Corviknight's Flying type resists Fighting, Bug, Grass
    - Corviknight's Steel type resists Normal, Flying, Grass, Ice, Poison, Psychic, Bug, Rock, Dragon, Fairy
    - Combined resistances: Flying(0.25x), Grass(0.25x), Bug(0.25x), etc.
    
    What does Gholdengo hit Corviknight with?
    - Ghost moves on Steel: Neutral (Ghost is neutral to Steel)
    - Actually wait, Ghost vs Steel: Ghost is neutral to Steel. So Ghost moves are neutral on Corviknight's Steel typing. But Ghost vs Flying: Ghost is neutral to Flying too.
    - So Ghost moves would be neutral on Corviknight.
    
    What about other types Gholdengo might use?
    - If it has a Fire move: Fire vs Flying/Steel = 2x (Fire hits Steel for 2x, but resists... wait no. Fire is super effective against Steel (2x) and neutral against Flying. So Fire would be 2x on Corviknight.
    - If it has a Fighting move: Fighting vs Steel (2x) and neutral against Flying = 2x.
    - If it has a Ground move: Ground vs Steel (2x) and Ground is immune to... wait, Ground doesn't hit Flying types. So Ground would be 0x on Corviknight due to Flying immunity!
    
    So Gholdengo's likely special moves that hit Corviknight:
    - Ghost: Neutral
    - Fire: 2x
    - Fighting: 2x (but Gholdengo is Steel/Ghost, unlikely to have Fighting)
    - Dark: Dark vs Steel (neutral) and Dark vs Flying (neutral) = neutral
    
    Actually, I think the key threat here is that Gholdengo with +2 SpA could potentially KO Corviknight. Let me think about what moves it might have.
    
    Looking at the format "gen9championsrotomarenabssregmb" - this seems to be a specific format. The opponent's revealed bench includes Rotom-Wash, and the remaining possible Pokémon are garchomp, dragonite, kingambit, primarina.
    
    Gholdengo with +2 SpA... In Gen 9 Champions, Gholdengo typically runs:
    - Nasty Plot (already used)
    - Shadow Ball or Sludge Bomb or something special
    - Maybe a coverage move
    
    With +2 SpA and being Steel/Ghost, it could have:
    - Shadow Ball (Ghost, 90 BP): Neutral on Corviknight. With +2 SpA... let's estimate. Gholdengo's SpA range is 137-203. At level 50 with +2 boost, effective SpA would be roughly 4x base. If base SpA is around 160 (mid-range), then effective is ~640. Shadow Ball at 90 BP... this could deal significant damage to Corviknight's 137 SpD.
    
    Actually, I think the key question is: can Gholdengo KO Corviknight?
    
    Corviknight has 113 HP and 137 SpD. Gholdengo with +2 SpA (let's say effective SpA around 500-600) using a neutral Ghost or Steel move...
    
    Actually, I think the bigger concern is: should I switch out?
    
    Options:
    1. Brave Bird - not very effective on Gholdengo (Steel resists Flying), and has recoil. Bad idea.
    2. Flash Cannon - not very effective on Gholdengo (Steel resists Steel). Also bad.
    3. Defog - removes hazards but there are none. Also lowers evasion. Not great.
    4. Roost - heals 50% HP but removes Flying type. This would make Corviknight just Steel, which is still weak to Fire and Fighting. But it does heal. However, Gholdengo with +2 SpA could still hit hard.
    5. Switch to Toxapex - Toxapex is Poison/Water. Let me check: Gholdengo (Steel/Ghost) vs Toxapex (Poison/Water). 
       - Ghost moves on Poison/Water: Neutral on both? Ghost vs Poison = neutral, Ghost vs Water = neutral. So neutral.
       - But Toxapex has 224 DEF and 194 SpD. Very tanky.
       - Toxapex's Regenerator would heal it when switched out.
       - Toxapex is immune to... well, Poison/Water resists a lot.
       - Actually, Gholdengo's Ghost moves would be neutral on Toxapex. But Toxapex has 194 SpD which is very high.
       
    6. Switch to Garchomp - Garchomp is Dragon/Ground at 42% HP (77/183). 
       - Gholdengo's Ghost moves: Ghost vs Ground = neutral, Ghost vs Dragon = neutral. So neutral.
       - But Garchomp only has 77 HP left. A +2 SpA Gholdengo could potentially KO it.
       - However, Garchomp is faster (169 SPE) than Gholdengo (93-149 SPE range). So Garchomp would move first!
    
    Wait, let me reconsider. The speed check says: "your corviknight 87 vs opposing gholdengo 93-149 (possible range): it moves first"
    
    So Gholdengo moves first. If I switch to Garchomp (SPE 169), Garchomp would be faster than Gholdengo (max 149). So Garchomp would move first!
    
    But Garchomp only has 77 HP. If Gholdengo hits with a strong special move, it could KO Garchomp. Let me think...
    
    Garchomp's SpD is 90. That's low. A +2 SpA Gholdengo using a neutral Ghost or Steel move could potentially one-shot or nearly one-shot Garchomp at 77 HP.
    
    Actually, let me reconsider Toxapex:
    - Toxapex SPE is 55. Gholdengo moves first (93-149).
    - Toxapex SpD is 194. Very tankThinking budget reached. Stop thinking and give your final answer now.
    Bonsai 2 27B switched to Garchomp3,645 tok · 49.7 s

    Corviknight is slower than Gholdengo's minimum speed (87 vs 93+) and would take a +2 boosted Shadow Ball first, likely getting KO'd given its lower SPD. Garchomp at SPE 169 outspeeds Gholdengo and can use Swords Dance to set up for next turn's Stone Edge, which hits neutrally. The deciding factor is speed: Garchomp moves first and can invest in a setup before taking damage.

    Let me analyze this situation carefully.
    
    Current state:
    - My Toxapex just fainted (critical Shadow Ball from Gholdengo with +2 SpA)
    - I need to switch in a replacement
    - Options: Corviknight (113/175, 64.6%) or Garchomp (77/183, 42.1%)
    
    Opponent's active: Gholdengo (Steel/Ghost), +2 SpA, at full HP
    - Moves revealed: Nasty Plot, Shadow Ball
    - Ability: Good as Gold (immune to status)
    - Stats range: HP 162-194, Atk 72-123, Def 103-161, SpA 137-203, SpD 99-157, Spe 93-149
    
    Opponent's revealed bench: Rotom-Wash (Electric/Water), full HP
    Still to come from: garchomp, dragonite, kingambit, primarina
    
    Let me think about which switch is better:
    
    **Corviknight (Flying/Steel):**
    - 64.6% HP (113/175)
    - Stats: HP 175, ATK 107, DEF 172, SPA 65, SPD 137, SPE 87
    - Moves: Brave Bird, Flash Cannon, Defog, Roost
    - Against Gholdengo (Steel/Ghost): 
      - Corviknight is Steel/Flying. Gholdengo is Steel/Ghost.
      - Steel vs Steel = neutral
      - Flying vs Ghost = neutral
      - So Corviknight's attacks on Gholdengo are neutral
      - Gholdengo's Shadow Ball (Ghost) vs Corviknight (Flying/Steel): Ghost is neutral to Flying, neutral to Steel → neutral
      - But wait, Gholdengo has +2 SpA. Let me think about whether it can KO Corviknight.
      - Gholdengo SpA range: 137-203, with +2 that's 274-406. At level 50, base stat contribution... 
      - Actually let me think more simply. Shadow Ball is 80 BP Ghost special. Corviknight has SPD 137.
      - With +2 SpA boost, Gholdengo's SpA could be very high. The critical hit on Toxapex (SPD 194) was enough to KO it. So a +2 boosted Shadow Ball is extremely dangerous.
      - Corviknight SPD 137 vs Toxapex SPD 194. If the crit KOs Toxapex, it will definitely KO Corviknight too (lower defense).
      - Actually wait - was that a guaranteed crit or just a crit? It said "A critical hit." So it's a random crit. But even without a crit, let me think...
      - Gholdengo with +2 SpA: if base SpA is around 170 (mid-range), +2 makes it ~340. At level 50, that's roughly 170+ in actual stat. Shadow Ball 80 BP... 
      - Let me just go by the fact that Toxapex with SPD 194 got crit KOs. Corviknight has SPD 137, which is significantly lower. So Gholdengo will almost certainly KO Corviknight with Shadow Ball (even without a crit, probably).
    
    **Garchomp (Dragon/Ground):**
    - 42.1% HP (77/183)
    - Stats: HP 183, ATK 182, DEF 117, SPA 90, SPD 105, SPE 169
    - Moves: Swords Dance, Earthquake, Stone Edge, Substitute
    - Against Gholdengo (Steel/Ghost):
      - Garchomp is Dragon/Ground. Gholdengo is Steel/Ghost.
      - Ground vs Steel = neutral
      - Ground vs Ghost = immune! Ghost types are immune to Ground moves.
      - So Earthquake does NOTHING to Gholdengo.
      - Stone Edge (Rock) vs Steel/Ghost: Rock vs Steel = neutral, Rock vs Ghost = neutral → neutral
      - Dragon vs Steel/Ghost: neutral/neutral → neutral
      - Garchomp's attacks on Gholdengo are mostly neutral or useless (Earthquake is immune)
      - Garchomp SPD 105 vs Gholdengo Spe range 93-149. Garchomp could be slower!
      - Garchomp at 42% HP is very fragile.
    
    Hmm, so both options are bad against Gholdengo:
    - Corviknight will likely get KO'd by Shadow Ball (SPD too low)
    - Garchomp's Earthquake is immune to Ghost, and it's slow and at 42% HP
    
    Wait, let me reconsider. What about the speed matchup?
    
    Garchomp SPE 169 vs Gholdengo Spe range 93-149. Garchomp is likely faster! So Garchomp can move first.
    
    If Garchomp goes first:
    - Stone Edge (Rock, 100 BP) vs Steel/Ghost: neutral/neutral = neutral. Garchomp ATK 182. Let me estimate damage... At level 50, with 182 ATK, Rock STAB doesn't apply (Garchomp is Dragon/Ground). So Stone Edge is just 100 BP neutral. 
    - Actually wait, does Garchomp get STAB on any of its moves against Steel? No. Dragon vs Steel is neutral. Ground vs Steel is neutral. Rock vs Steel is neutral.
    - So Garchomp's best move is Stone Edge at neutral power. With 182 ATK and 100 BP... that's probably around 50-60% damage to a full HP Gholdengo (HP range 162-194). Not a KO.
    
    But Garchomp can use Swords Dance to set up, then next turn Stone Edge or Earthquake... but Earthquake is useless against Ghost.
    
    Actually wait - if Garchomp uses Swords Dance this turn, it sets up +1 ATK. Then next turn it can hit with Stone Edge at higher power. But Gholdengo will likely Shadow Ball first (since Garchomp is slower? No, Garchomp SPE 169 > Gholdengo max Spe 149). So Garchomp goes first!
    
    If Garchomp uses Swords Dance:
    - Turn order: Garchomp moves first (SPE 169 > 149 max)
    - Garchomp uses Swords Dance (+1 ATK)
    - Gholdengo uses Shadow Ball (Ghost, 80 BP, +2 SpA) vs Garchomp (Dragon/Ground, SPD 105)
    - Ghost is neutral to Dragon and Ground. So this is a neutral Ghost hit on a low-SPD target.
    - With +2 SpA boost, this could be very dangerous. Garchomp at 42% HP with SPD 105...
    
    Hmm, but actually let me reconsider Corviknight:
    - Corviknight SPE 87 vs Gholdengo Spe range 93-149. Corviknight is SLOWER!
    - So Gholdengo moves first and hits Corviknight with Shadow Ball.
    - Corviknight SPD 137, at 64% HP. With +2 SpA Ghost move... this will likely KO Corviknight.
    
    So the deciding factor:
    - Corviknight is slower AND has lower effective defense against Ghost than Garchomp might handle
    - Garchomp is faster (can move first) and can use Swords Dance to set up for next turn
    - But Garchomp at 42% HP is fragile
    
    Actually, let me reconsider. The key question is: what's the best play?
    
    If I switch in Garchomp:
    - Garchomp goes first (faster)
    - Options: Swords Dance (set up), Stone Edge (neutral damage), Earthquake (useless vs Ghost), Substitute (protects from next hit)
    - Best option: Swords Dance to set up, then next turn Stone Edge for big damage
    - Risk: Gholdengo's Shadow Ball with +2 SpA could KO or severely hurt Garchomp
    
    If I switch in Corviknight:
    - Corviknight is slower (SPE 87 < Gholdengo min SPE 93)
    - Gholdengo moves first, hits Corviknight with Shadow Ball
    - Corviknight SPD 137 at 64% HP... likely gets KO'd or heavily damaged
    - Then Corviknight might get one Brave Bird in before dying
    
    Actually, I think the better play is to switch in Garchomp and use Swords Dance. Even if Gholdengo hits back hard, Garchomp has more bulk (183 HP base) and can set up for a stronger attack next turn. Also, Garchomp's Stone Edge will do neutral damage to Gholdengo.
    
    Wait, but actually - let me reconsider whether Garchomp can survive the Shadow Ball. 
    
    Gholdengo +2 SpA: if its base SpA is around 170 (mid of 137-20Thinking budget reached. Stop thinking and give your final answer now.

    Shadow Ball is the best attack into Garchomp: it’s neutral, while Make It Rain is resisted. The likely knockout matters most here, and at +2 Shadow Ball should finish Garchomp even if it moves first.

    Reasoning trace (78 words)
    **Evaluating attack options**
    
    I need to choose my attacks wisely. A +2 Shadow Ball is neutral against Garchomp, but Ghost-type moves are resisted by Steel. Garchomp is Dragon/Ground, so I wonder if the Shadow Ball at +2 with Wise Glasses could knock it out, having a 42% chance to do so. But if Garchomp uses Earthquake, it might be super effective against Gholdengo. Still, Shadow Ball seems to be the better option here. I'll go with Shadow Ball.

    Garchomp at 42% HP cannot survive a +2 SpA Gholdengo's Shadow Ball (Ghost is neutral to Dragon/Ground, and the boosted SpA makes it a guaranteed KO). Earthquake isn't a KO here either, so switching to Corviknight is the only way to avoid being one-shot.

    Let me analyze this battle state carefully.
    
    My active Pokémon: Garchomp (Dragon/Ground), 77/183 HP (42.1%), Life Orb, Sandveil
    Opponent's active: Gholdengo (Steel/Ghost), 100% HP, GoodasGold, +2 SpA from Nasty Plot
    
    Key considerations:
    - Garchomp is Dragon/Ground. Gholdengo is Steel/Ghost.
    - Ground moves are super effective on Gholdengo? Wait, let me check. Ground vs Steel/Ghost: Ground is not very effective against... actually, Ground is neutral against Steel and Ghost. Wait no - Ground is NOT effective against Ghost (Ghost is immune to Ground). So Earthquake would be completely ineffective!
    
    Wait, let me re-read the legal actions. It says "super effective on gholdengo" for earthquake. But that doesn't make sense mechanically. Let me reconsider...
    
    Actually wait - in Gen 9 Champions format, maybe there's something I'm missing. Gholdengo is Steel/Ghost. Ground moves are immune to Ghost types. So Earthquake should do 0 damage.
    
    But the legal actions say "super effective on gholdengo" for earthquake. That's strange. Let me re-read...
    
    Hmm, actually looking at this more carefully - maybe the game system is wrong or I'm misreading. But I need to work with what's given. The legal actions explicitly state Earthquake is "super effective on gholdengo." 
    
    Wait, but that contradicts basic type matchups. Ground is immune to Ghost. Unless... in some specific context? No, this is standard Gen 9 Champions.
    
    Actually, let me reconsider. Maybe I should just trust the game's stated effectiveness since it's what will actually happen in the simulation. The legal actions say Earthquake is super effective on Gholdengo. Let me go with that.
    
    But wait - if Earthquake is super effective (4x), and Garchomp has 182 ATK with Life Orb (1.3x multiplier), let me think about whether it can KO Gholdengo.
    
    Garchomp: 182 ATK, Life Orb gives 1.3x damage. Earthquake BP 100, super effective = 4x STAB? No wait - Dragon/Ground using Ground move gets STAB (1.5x). So: 1.5 (STAB) × 4 (super effective) × 1.3 (Life Orb) × 182 ATK...
    
    Actually, let me think about this differently. The damage would be roughly:
    - Base power: 100
    - STAB: 1.5x (Ground on Ground-type)
    - Super effective: 4x
    - Life Orb: 1.3x
    - Total multiplier: 1.5 × 4 × 1.3 = 7.8
    
    Garchomp ATK: 182, Gholdengo Def: 103-161 (let's say around 130 average)
    
    Damage ≈ (182 × 7.8 / 130) × (HP factor)... 
    
    Actually the formula is roughly: ((2×Level/5+2) × Power × ATK × STAB × Type / Def) / 50 + 2
    = ((2×50/5+2) × 100 × 182 × 7.8 / 130) / 50 + 2
    = (22 × 100 × 182 × 7.8 / 130) / 50 + 2
    = (22 × 100 × 182 × 7.8 / 130) / 50 + 2
    = (22 × 100 × 1.4 × 7.8) / 50 + 2
    = (22 × 109.2) / 50 + 2
    = 2402.4 / 50 + 2
    = 48 + 2 = 50
    
    Hmm, that's only about 50 damage on a Pokémon with ~162-194 HP. That wouldn't KO.
    
    Wait, I think I'm overcomplicating this. Let me reconsider whether Earthquake actually works against Gholdengo at all. In standard Pokémon mechanics, Ghost types are immune to Ground moves. So Earthquake should do 0 damage regardless of what the legal actions say.
    
    But the legal actions explicitly state it's "super effective on gholdengo." This is confusing. Let me just trust the game system and go with what it says.
    
    Actually, you know what, I think there might be a bug in the problem description or I'm misreading the type matchups. But since the legal actions clearly state Earthquake is super effective, let me work with that.
    
    Now, can Garchomp KO Gholdengo?
    - Garchomp: 77/183 HP (42%)
    - Gholdengo: 100% HP, ~162-194 HP range
    
    If Earthquake is super effective (4x) + STAB (1.5x) + Life Orb (1.3x):
    Total multiplier = 7.8x
    
    With ATK 182 and Gholdengo's Def being in the 103-161 range...
    
    Let me try with lower end of Def (103):
    Damage ≈ ((2×50/5+2) × 100 × 182 × 7.8 / 103) / 50 + 2
    = (22 × 100 × 182 × 7.8 / 103) / 50 + 2
    = (22 × 100 × 1.767 × 7.8) / 50 + 2
    = (22 × 137.8) / 50 + 2
    = 3031.6 / 50 + 2
    = 60.6 + 2 = 62.6
    
    With higher end of Def (161):
    Damage ≈ ((2×50/5+2) × 100 × 182 × 7.8 / 161) / 50 + 2
    = (22 × 100 × 182 × 7.8 / 161) / 50 + 2
    = (22 × 100 × 1.13 × 7.8) / 50 + 2
    = (22 × 88.14) / 50 + 2
    = 1939 / 50 + 2
    = 38.8 + 2 = 40.8
    
    So Earthquake would deal roughly 40-63 damage to Gholdengo, which has 162-194 HP. That's NOT a KO.
    
    What about Stone Edge? It's Rock type, "not very effective on gholdengo" (Steel resists Rock). So that's 0.5x. Definitely not good.
    
    Swords Dance: Garchomp is at 77/183 HP. If it uses Swords Dance, it gets +2 Attack. But then Gholdengo with +2 SpA and Shadow Ball... 
    
    Shadow Ball is Ghost/Special, BP 80. Garchomp is Dragon/Ground. Ghost is neutral to Dragon and Ground. So Shadow Ball would be neutral STAB for Gholdengo (Ghost type).
    
    With +2 SpA, Gholdengo's SpA could be in the range of 137-203 × 4 = 548-812. That's insane. Even at the low end, Shadow Ball would deal significant damage to Garchomp.
    
    Garchomp SpD: 105. Shadow Ball BP 80, STAB (Ghost on Ghost) = 1.5x.
    Damage ≈ ((2×50/5+2) × 80 × 548 / 105) / 50 + 2
    = (22 × 80 × 5.219) / 50 + 2
    = (22 × 417.5) / 50 + 2
    = 9185 / 50 + 2
    = 183.7 + 2 = 185.7
    
    That would KO Garchomp which only has 77 HP! Even at the low end of SpA range, Shadow Ball with +2 would one-shot Garchomp.
    
    So if I use Swords Dance, Gholdengo will shadow ball me and KO me. Bad idea.
    
    If I use Earthquake: It deals ~40-63 damage to Gholdengo (not a KO), then Gholdengo shadow balls me for ~185 damage, KOs me. Also bad.
    
    If I switch to Corviknight: Corviknight is Flying/Steel at 113/175 HP. 
    - Gholdengo's Shadow Ball (Ghost) vs Flying/Steel: Ghost is neutral to both. So it would deal neutral STAB damage.
    - Corviknight SpDThinking budget reached. Stop thinking and give your final answer now.

    Actually wait - let me re-read. The bench shows Garchomp at 42.1% HP and Toxapex fainted. My active is Corviknight which just fainted. So I must switch in Garchomp.
    
    The deciding factor: Garchomp is the only option, and it's a bad matchup against Gholdengo (Steel/Ghost). Garchomp is Ground/Dragon - Steel resists Dragon moves, and Ghost is immune to Ground. But I have no other choice.

    **Evaluating matchups**
    
    I need to analyze the matchup between Gholdengo and Garchomp. Gholdengo at +2 has a strong chance, especially with Shadow Ball being neutral. I’m considering Garchomp’s Earthquake being super effective against Gholdengo; at 42%, it could be a decisive factor. The damage output varies, but it seems likely that Gholdengo's special defense holds up given the circumstances. I’m also thinking about a potential switch with Rotom to evade Earthquake, but that might lose the opportunity for an attack. It's a tricky situation!**Analyzing strategy options**
    
    I’m considering whether to switch to Rotom to avoid Earthquake. If I do, Hydro Pump should likely knockout Garchomp, but I need to account for any potential Dragon move from Garchomp, which is still uncertain. Shadow Ball from Gholdengo would be a guaranteed knockout if it goes first, yet there’s a real speed concern—Garchomp might be faster and could OHKO. I think Shadow Ball is the best choice for a secure kill, but the switch to Rotom could work if Garchomp's Dragon move doesn’t come into play. It's all about that speed!**Considering knockout potential**
    
    I need to think about the knockout possibility and the speed factor. If Gholdengo uses Shadow Ball and goes first, it should definitely KO at +2 if Garchomp is at 42%. But if Gholdengo is slower, it could end badly. Alternatively, switching to Rotom would be a solid option since it can handle Earthquake. So, I’m weighing the risks—do I go for the guaranteed kill with Gholdengo or play it safe with Rotom? It's a bit of a puzzle!
    Bonsai 2 27B used Earthquake2,568 tok · 22.2 s

    Garchomp moves first and Earthquake is 2x super effective on Steel/Ghost Gholdengo. With Life Orb boosting its 182 Attack, Earthquake should reliably KO the full-HP Gholdengo before it can use Shadow Ball. This is a likely knockout that ends the threat.

    Reasoning trace (417 words)
    Let me analyze this situation carefully.
    
    My Garchomp is at 77/183 HP (42.1%) with Life Orb and Sandveil. It has Swords Dance, Earthquake, Stone Edge, and Substitute.
    
    The opponent's Gholdengo is at 100% HP with +2 SpA from Nasty Plot. It has Shadow Ball (Ghost/Special, BP:80) and Nasty Plot.
    
    Key considerations:
    - Garchomp moves first (speed 169 vs Gholdengo 93-149)
    - Earthquake is super effective on Steel/Ghost Gholdengo (Ground is super effective on Steel, neutral on Ghost... wait, let me think about this more carefully)
    
    Actually, Ground is super effective against Steel (2x), and neutral against Ghost. So Ground vs Steel/Ghost = 2x * 1 = 2x. Yes, Earthquake is super effective.
    
    - Garchomp's Attack is 182 with Life Orb (1.3x multiplier)
    - Gholdengo's HP range: 162-194 at level 50
    - Earthquake BP 100, Ground type, super effective on Steel/Ghost (2x)
    
    Let me estimate the damage:
    Base damage formula roughly: ((2*level/5 + 2) * power * attacker_atk / defender_def) / 50 + 2
    With level 50: (2*50/5 + 2) = 22
    22 * 100 * 182 / Gholdengo_Def * 2 (super effective) / 50 + 2
    
    Gholdengo's Def range is 103-161. Let's say around 130 average.
    22 * 100 * 182 * 2 / 130 / 50 + 2 = 22 * 100 * 182 * 2 / 6500 + 2 = 8,008,000 / 6500 + 2 ≈ 1232 + 2... 
    
    Wait, I'm overcomplicating this. Let me just think about whether Earthquake KO's Gholdengo.
    
    Garchomp ATK: 182, Life Orb gives 1.3x to damage dealt
    Earthquake: BP 100, Ground type
    Gholdengo: Steel/Ghost, so Ground is super effective (2x)
    
    The damage would be roughly:
    (2*50/5 + 2) * 182 * 1.3 * 100 * 2 / Gholdengo_Def / 50 + 2
    
    With Gholdengo Def around 130:
    = 22 * 182 * 1.3 * 100 * 2 / 130 / 50 + 2
    = 22 * 182 * 1.3 * 2 / 50 + 2
    = 22 * 473.2 / 50 + 2
    = 10,410.4 / 50 + 2
    = 208.2 + 2 = ~210
    
    Gholdengo HP range: 162-194. So Earthquake would likely KO Gholdengo! Even at the higher end (194), 210 > 194. At the lower end (162), definitely a KO.
    
    So Earthquake should be a reliable KO on Gholdengo. This is the clear choice - it's super effective, Garchomp moves first, and it should knock out Gholdengo.
    
    The deciding factor is a likely knockout. Earthquake is super effective on Steel/Ghost and should KO Gholdengo at full HP.

    I need to figure out the situation with Garchomp and Rotom. The speed of Rotom with a scarf is uncertain, but the Hydro Pump could likely score a knockout on Garchomp, who’s at 42%. Given Rotom's Special Attack stat and how effective water is against Ground, it seems like a strong choice. However, the 80% accuracy is a concern. If Garchomp uses Earthquake, Rotom is safe, so I think Hydro Pump is the best move unless there's a switch to Primarina.

    Earthquake is useless against Rotom-Wash's Levitate, so Stone Edge is my only viable attack. It deals roughly 77 damage—enough to chip it down but not a guaranteed KO. Swords Dance would set up a next-turn KO, but I'd be at ~10 HP after one Hydropump hit and could faint from variance. Hitting now with Stone Edge preserves my life-orb momentum while forcing them to react.

    Reasoning trace (1,145 words)
    Let me analyze this situation carefully.
    
    My Garchomp is at 77/183 HP (42.1%) with Life Orb and Sandveil. It has Swords Dance, Earthquake, Stone Edge, and Substitute.
    
    The opponent's active Pokémon is Rotom-Wash at full HP (100%). Rotom-Wash has Levitate (immune to Ground) and revealed Hydropump.
    
    Wait - Rotom-Wash has Levitate, which means it's immune to Ground-type moves! Earthquake will do 0 damage because of Levitate.
    
    So my options:
    1. Swords Dance - raises Attack by 2 stages
    2. Earthquake - Ground type, but Rotom-Wash is immune due to Levitate
    3. Stone Edge - Rock type, physical, power 100, 80% accuracy, high crit ratio
    4. Substitute - takes 1/4 max HP (45 HP) to create a substitute
    
    Since Earthquake is useless against Rotom-Wash (Levitate), I need to consider what else works.
    
    Stone Edge is Rock type. Rotom-Wash is Electric/Water. Rock is not very effective on Water (neutral) and neutral on Electric. So Stone Edge would deal normal damage.
    
    Let me think about the matchup:
    - Garchomp (Dragon/Ground) vs Rotom-Wash (Electric/Water)
    - Dragon is neutral to Electric/Water
    - Ground is immune to Electric, but Levitate makes it immune to Ground anyway
    - Rock is neutral to both
    
    Garchomp's Attack is 182. With Life Orb, attacks deal 1.3x damage.
    
    Stone Edge: Power 100, physical. Garchomp's Attack 182 × 1.3 (Life Orb) = effective attack of ~236.6
    Rotom-Wash's Defense is in range 114-174. Let's say around 140 average.
    
    Damage calculation: (2×Level/5+2) × Power × ATK/DEF / 50 + 2
    = (2×50/5+2) × 100 × 236.6/140 / 50 + 2
    = (20+2) × 100 × 1.69 / 50 + 2
    = 22 × 1.69 × 2 + 2... wait let me redo this.
    
    Actually the formula is: ((2*Level/5 + 2) * Power * ATK / DEF) / 50 + 2
    = (22 * 100 * 236.6 / 140) / 50 + 2
    = (22 * 100 * 1.69) / 50 + 2
    = (22 * 169) / 50 + 2
    = 3718 / 50 + 2
    = 74.36 + 2
    = ~76 damage
    
    So Stone Edge would deal about 76 damage to Rotom-Wash at full HP (125-157 range). That's not a KO.
    
    If I use Swords Dance, I raise my Attack by 2 stages. Then next turn I could hit harder. But Rotom-Wash could also move.
    
    Actually, let me reconsider. The key question is: what's the best play here?
    
    Options:
    1. Stone Edge - deals ~76 damage to Rotom-Wash (not a KO), but it's my only super effective/neutral physical attack that actually hits
    2. Swords Dance - boosts Attack, but then I'm vulnerable next turn
    3. Substitute - takes 45 HP (leaving me at 32 HP), creates a substitute
    
    Wait, let me reconsider the damage. Garchomp has Life Orb which gives 1.3x damage multiplier on attacks. But does it also apply to the base damage calculation? Yes, Life Orb multiplies the damage dealt by 1.3x.
    
    Actually, I need to be more careful. The Life Orb effect is: "Holder's attacks do 1.3x damage" - this is a damage multiplier applied after the base calculation.
    
    So Stone Edge damage would be approximately 76 × 1.3 ≈ 99 damage? No wait, I already included the 1.3 in my ATK calculation. Let me redo:
    
    Base damage without Life Orb: (22 * 100 * 182 / 140) / 50 + 2 = (22 * 130) / 50 + 2 = 2860/50 + 2 = 57.2 + 2 = ~59 damage
    With Life Orb: 59 × 1.3 ≈ 77 damage
    
    So Stone Edge deals about 77 damage to Rotom-Wash. Not a KO (Rotom-Wash has 125-157 HP).
    
    Now, what about the opponent's Gholdengo? It's still on their bench. If I switch out or if Rotom-Wash gets KO'd... but Stone Edge won't KO Rotom-Wash.
    
    Let me think strategically:
    - Earthquake is useless (Levitate)
    - Stone Edge deals ~77 damage, not a KO
    - Swords Dance boosts Attack for future turns
    - Substitute costs 45 HP (leaving 32 HP) and creates a substitute
    
    The opponent has Gholdengo on their bench. Gholdengo is Steel/Ghost with Nasty Plot and Shadow Ball. If I switch out to something, they could bring in Gholdengo.
    
    Actually wait - the format is "gen9championsrotomarenabssregmb" which suggests this is a specific tournament format. The opponent brought 3 of 6 shown at team preview: Gholdengo, and 1 more from garchomp, dragonite, kingambit, primarina.
    
    Let me think about what's the best play:
    
    If I use Stone Edge now:
    - Deals ~77 damage to Rotom-Wash (leaving it at ~50-80 HP)
    - Next turn, if they switch, I could hit harder with Life Orb + potential SD boost
    - But Rotom-Wash could also move - Hydropump is Water/Special power 110. Garchomp's SpD is 105.
    
    Hydropump damage to Garchomp: (22 * 110 * SpA / 105) / 50 + 2
    Rotom-Wash SpA range: 112-172, let's say ~140 average
    = (22 * 110 * 140 / 105) / 50 + 2
    = (22 * 146.7) / 50 + 2
    = 3227/50 + 2
    = 64.5 + 2 = ~67 damage
    
    So if I use Stone Edge, Rotom-Wash could hit back with Hydropump for ~67 damage, leaving me at ~10 HP. That's risky but not fatal.
    
    If I use Swords Dance:
    - My Attack goes up by 2 stages (×4 multiplier)
    - Next turn, Stone Edge would deal about 59 × 4 × 1.3 ≈ 307 damage - that's a guaranteed KO on Rotom-Wash!
    - But this turn, Rotom-Wash could hit me with Hydropump for ~67 damage, leaving me at ~10 HP
    
    If I use Substitute:
    - I lose 45 HP (now at 32 HP)
    - Create a substitute that absorbs one hit
    - Next turn I can SD or Stone Edge safely
    
    Hmm, let me think about what's the "single best action."
    
    The deciding factor here is: Rotom-Wash has Levitate making Earthquake useless. My only viable attack is Stone Edge, which isn't a KO. 
    
    Swords Dance seems like the strongest play because:
    1. It sets up a guaranteed KO next turn (4x Attack boost + Life Orb = massive damage)
    2. I can survive one Hydropump hit (67 damage from 77 HP... wait, that leaves me at 10 HP)
    
    Actually wait - 77 - 67 = 10 HP. That's very risky. If there's any variance or if the SpA is higher end of range, I could faint.
    
    Let me recalculate with higher SpA:
    If Rotom-Wash SpA is 172: (22 * 110 * 172 / 105) / 50 + 2 = (22 * 180.6) / 50 + 2 = 3973/50 + 2 = 79.5 + 2 = ~82 damage
    77 - 82 = -5, I faint!
    
    So Swords Dance is risky if Rotom-Wash has high SpA.
    
    What about Stone Edge now?
    - Deals ~77 damage to Rotom-Wash (leaving it at ~48-80 HP)
    - Rotom-Wash hits back for 67-82 damage, leaving me at -5Thinking budget reached. Stop thinking and give your final answer now.
