   Mirror matchup vs scripted control bot. Picking Alakazam (fastest, Magic Guard immune to status, can Nasty Plot), Garchomp (physical sweeper, EQ for Steel), Metagross (Stealth Rock support, bulk, more EQ). Control bot likely sets up or uses status; Magic Guard and speed advantage counter that.

   Reasoning trace (737 words)

   Let me analyze this matchup. The opponent is a scripted control bot with an exact copy of my team. I need to pick 3 Pokémon that give me the best advantage.
   
   My team options:
   - Garchomp (Dragon/Ground): Life Orb, Rough Skin, 183/182/115/90/107/169. Moves: Earthquake, Dragon Claw, Swords Dance, Stone Edge
   - Gengar (Ghost/Poison): Gengarite, Cursed Body, 135/76/80/182/97/178. Moves: Shadow Ball, Sludge Bomb, Focus Blast, Nasty Plot
   - Alakazam (Psychic): Alakazite, Magic Guard, 130/63/65/187/117/189. Moves: Psychic, Focus Blast, Energy Ball, Nasty Plot
   - Metagross (Steel/Psychic): Metagrossite, Clear Body, 155/187/150/103/112/134. Moves: Earthquake, Zen Headbutt, Bullet Punch, Stealth Rock
   - Skarmory (Steel/Flying): Leftovers, Sturdy, 172/100/211/54/92/90. Moves: Roost, Spikes, Taunt, Whirlwind
   - Gliscor (Ground/Flying): Focus Sash, Poison Heal, 152/115/194/58/127/115. Moves: Earthquake, U-turn, Toxic, Swords Dance
   
   Since the opponent has the exact same team, this is a mirror-like matchup. The key considerations:
   
   1. Speed ties: If both bring the same Pokémon, speed ties will be common. My Garchomp has 169 Spe, Gengar 178, Alakazam 189, Metagross 134, Skarmory 90, Gliscor 115.
   
   2. The opponent is a "scripted control bot" - this suggests it might prioritize setup (Nasty Plot, Swords Dance), entry hazards (Stealth Rock, Spikes), or status (Toxic, Taunt).
   
   3. Since it's a mirror, I want to pick a team that can handle the opponent's likely picks.
   
   Strategy considerations:
   - Alakazam with Magic Guard is very strong - it's immune to status, and with 189 Spe it outspeeds everything. With Alakazite (Mega), it becomes even faster. Focus Blast hits Steel-types.
   - Gengar with Cursed Body can trap and KO. 178 Spe is fast.
   - Garchomp is a physical attacker with 169 Spe, good bulk.
   - Metagross with Stealth Rock is a great support option.
   - Skarmory with Spikes and Taunt is great for control.
   - Gliscor with Focus Sash and Toxic is a good tank.
   
   For a control bot opponent, I think a good team would be:
   - Alakazam (leader): Fastest Pokémon, Magic Guard makes it immune to status, can Nasty Plot or just hit hard. Focus Blast handles Steel-types.
   - Garchomp: Physical attacker, can Swords Dance, Earthquake hits Steel-types.
   - Metagross: Can set up Stealth Rock, has good bulk, Earthquake for coverage.
   
   Actually, let me think about this differently. Since the opponent is a "control bot," it might:
   - Set up hazards (Stealth Rock, Spikes)
   - Use status moves (Toxic, Taunt)
   - Set up (Nasty Plot, Swords Dance)
   
   Against a control bot, I want:
   - Fast attackers that can strike before setup
   - Pokémon that can break through hazards
   - Maybe a Taunt user to prevent setup
   
   Let me go with:
   1. Alakazam (leader) - Fastest, Magic Guard (immune to status), can Nasty Plot or just hit. With Alakazite it gets even faster. Focus Blast for Steel-types.
   2. Garchomp - Physical sweeper, Earthquake for Steel, can Swords Dance. Life Orb for extra power.
   3. Metagross - Can set Stealth Rock, has good defensive stats, Earthquake for coverage.
   
   Actually, wait. If the opponent also brings Alakazam, we'll have a speed tie at 189 (or whatever the mega speed is). Let me think...
   
   Actually, the opponent's Alakazam has Spe range 126-189, so it could be slower. But if it's the same spread, it's a tie.
   
   Let me reconsider. For a control bot:
   - Alakazam: Magic Guard is amazing against status. 189 Spe means it goes first almost always. Can Nasty Plot to become a monster.
   - Garchomp: Good physical presence, Earthquake hits Steel-types hard.
   - Skarmory: Can Taunt to prevent setup, set Spikes, Roost to heal. Sturdy gives it a free hit.
   
   Actually, I think Alakazam + Garchomp + Metagross is solid:
   - Alakazam leads, outspeeds most things, Magic Guard protects from status
   - Garchomp provides physical pressure, Earthquake for Steel
   - Metagross can set Stealth Rock and provides another Earthquake
   
   Or Alakazam + Garchomp + Skarmory:
   - Alakazam for speed and special offense
   - Garchomp for physical offense
   - Skarmory for Taunt (prevents setup), Spikes, and tanking
   
   I'll go with Alakazam, Garchomp, Metagross. The reasoning:
   - Alakazam leads: fastest, Magic Guard, can Nasty Plot or just hit hard
   - Garchomp: physical sweeper, Earthquake for Steel-types
   - Metagross: Stealth Rock support, additional physical pressure, good bulk
   
   This gives me both physical and special offense, speed, and hazard support. Against a control bot that might try to set up or use status, Magic Guard on Alakazam is great, and I have multiple Earthquake users for Steel-types.
   
   Let me go with: Alakazam, Garchomp, Metagross
   

2. Turn 1
   PokéChamp used Earthquake
   Qwen3.8 27B used Nastyplotmega4,191 tok · 475.6 s · $0.0009

   Mirror matchup vs control bot. Leading Alakazam (Magic Guard, fastest) vs their Garchomp. I outspeed (189 vs max 169). Plan: Mega + Nasty Plot to set up +2 SpA while safe from status. Next turn OHKO/2HKO their Garchomp with boosted special. Garchomp's moves are all physical so they'll hit Magic Guard, but I should survive one hit. Save Garchomp/Metagross for later threats.

   Reasoning trace (1,003 words)

   Let me analyze this battle:
   
   - I'm leading with Alakazam (Magic Guard, 189 Spe) vs their Garchomp (109-169 Spe)
   - I outspeed their Garchomp for sure (189 vs max 169)
   - My Alakazam has Magic Guard, so it's immune to status effects, sand damage, etc.
   - I can Mega Evolve Alakazam this turn
   
   Strategy considerations:
   - If I Mega Evolve and use Nasty Plot, I get +2 SpA AND Mega Alakazam's boosted stats. Mega Alakazam gets 160 SpA base (from 135), so with Nasty Plot it becomes very strong.
   - If I Mega Evolve and use Psychic, I get a strong hit immediately.
   - Their Garchomp is Dragon/Ground. Psychic is neutral on Garchomp (Dragon resists Psychic? No - Dragon is neutral to Psychic. Ground is neutral to Psychic. So Psychic is neutral).
   - Focus Blast is Fighting type - neutral on Dragon/Ground.
   - Energy Ball is Grass - super effective on Ground! But Garchomp is Dragon/Ground, so Grass is 2x on Ground but Dragon resists Grass (0.5x). Net: 1x. Wait, let me recalculate. Grass vs Dragon/Ground: Grass is super effective on Ground (2x) but not very effective on Dragon (0.5x). So net is 1x. Actually wait - Dragon resists Grass? Let me think... Dragon type: resists Fire, Water, Grass, Electric. Yes, Dragon resists Grass. So Grass vs Dragon/Ground = 2x (Ground) * 0.5x (Dragon) = 1x. Neutral.
   
   So all my special moves are neutral on Garchomp.
   
   Best option: Mega Evolve + Nasty Plot. This gives me:
   - Mega Alakazam with boosted stats (Mega Alakazam: 130 HP, 150 Atk, 65 Def, 175 SpA, 95 SpD, 150 Spe)
   - Wait, actually Mega Alakazam stats: HP 130, Atk 150, Def 65, SpA 175, SpD 95, Spe 150. Hmm, that's actually slower than regular Alakazam (150 vs 189 base). But in this battle, the stats are already set. Let me re-read.
   
   Actually, looking at the stats given: Alakazam has Spe 189. Mega Alakazam would change the stats. But in Pokémon Showdown, when you Mega Evolve, the stats change to the Mega form's stats. Mega Alakazam has base 150 Speed, which at level 50 with the same EVs/nature would be... well, the stats shown are already calculated. The Mega form would recalculate.
   
   Actually, I think in this context, the stats shown are the current stats, and Mega Evolution would change them. But I don't have the exact Mega stats listed. Let me just focus on the strategic decision.
   
   The key question: Should I Nasty Plot or attack?
   
   If I Nasty Plot (with or without Mega):
   - I set up, then next turn I can OHK or 2HKO their Garchomp
   - Their Garchomp can attack me this turn (I'm slower after Mega? No, I go first this turn since I'm 189 vs max 169)
   - Wait, if I Mega Evolve, my speed might change. Mega Alakazam base speed is 150, which is lower than regular Alakazam's 150... wait, regular Alakazam is 120 base speed. Mega Alakazam is 150 base speed. So Mega Alakazam is FASTER.
   
   Let me reconsider: Regular Alakazam base speed is 120. Mega Alakazam base speed is 150. So Mega Alakazam is faster. At level 50, with the stats shown (189 Spe for regular), Mega would be even faster.
   
   So Mega + Nasty Plot: I set up +2 SpA, Mega Alakazam is faster, and I have Magic Guard. Their Garchomp can't do much to a Magic Guard Alakazam with special attacks (Garchomp's moves are all physical: Earthquake, Dragon Claw, Stone Edge, Swords Dance). Physical attacks DO hit Magic Guard Pokémon. So Garchomp can still hurt me with EQ or Dragon Claw.
   
   But if I Nasty Plot, I'm safe from status and I'm faster. Next turn I can hit with a strong special move.
   
   Actually, the best play might be:
   - Turn 1: Mega + Nasty Plot (set up, become very strong)
   - Turn 2: Hit with Psychic or Focus Blast for massive damage
   
   Or:
   - Turn 1: Mega + Psychic (hit hard immediately)
   - Turn 2: Nasty Plot or hit again
   
   Given that their Garchomp is a physical attacker and my Alakazam has Magic Guard (immune to status but NOT to physical damage), I need to be careful. Garchomp's Earthquake would hit me for neutral damage.
   
   Let me think about damage:
   - Mega Alakazam Psychic vs Garchomp: Psychic is neutral on Dragon/Ground. With Mega Alakazam's high SpA (let's say around 175 base, so at level 50 maybe around 150-160 effective SpA), a 90 BP move would do significant damage.
   - After Nasty Plot, it would be even more.
   
   I think the best play is Mega + Nasty Plot. This maximizes my setup while being safe (I go first, set up, and their Garchomp's physical attacks are the only thing that can hurt me, but I can switch or take the hit).
   
   Actually wait - if I Nasty Plot, their Garchomp will attack me. With Magic Guard, I'm only hit by direct attacks. Garchomp's moves are all physical, so they WILL hit me. Let me estimate: Garchomp's EQ (100 BP physical) vs Alakazam (65 Def base, 117 SpD base). Physical defense is 65 base. At level 50, that's probably around 65-70 effective. Garchomp's Atk is 135-200. So EQ could do maybe 40-60% damage to my Alakazam.
   
   If I Mega + Psychic instead: I hit first (I'm faster), deal significant damage, then Garchomp hits back. I might survive and continue.
   
   Hmm, but the control bot... it might try to set up or use status. If it uses Swords Dance, I want to be ready to OHKO it next turn.
   
   I'll go with Mega + Nasty Plot. The reasoning:
   1. I go first (faster)
   2. I set up +2 SpA
   3. Mega Alakazam is very strong offensively
   4. Magic Guard protects from any status the bot might try
   5. Next turn I can likely OHKO or heavily damage their Garchomp
   6. Even if Garchomp hits me with EQ, I should survive (130 HP, and the damage might be around 50-60%)
   
   Let me go with option 8: MOVE: nastyplot [MEGA]
   

   Qwen3.8 27B switched to Garchomp5,422 tok · 43.5 s · $0.0070

   Alakazam fainted after Nasty Plot (got +2 SpA) but was KO'd by their Garchomp's EQ (Life Orb recoil left them at 90%). Their Garchomp is the only confirmed opponent. Metagross gets OHKO'd by EQ (2x SE vs Steel, ~200 dmg to 155 HP). Garchomp survives EQ (~70% dmg to 183 HP) and can mirror-fight. Switching Garchomp in to fight the mirror. Plan: EQ to chip, then KO next turn.

   Reasoning trace (1,589 words)

   Let me analyze the situation:
   
   1. My Alakazam fainted after using Nasty Plot (got +2 SpA) but was KO'd by Garchomp's Earthquake (with Life Orb recoil).
   2. The opponent's Garchomp is at 90% HP (took Life Orb recoil from Earthquake).
   3. I need to switch to either Garchomp or Metagross.
   
   Let me think about which to send in:
   
   **Garchomp vs their Garchomp:**
   - My Garchomp: HP 183, Atk 182, Def 115, SpA 90, SpD 107, Spe 169
   - Their Garchomp: at 90% HP, has Life Orb, used Earthquake
   - Both are Dragon/Ground, so they're immune to each other's Electric moves (not relevant here)
   - Garchomp vs Garchomp: Dragon/Ground vs Dragon/Ground
     - Earthquake: Ground vs Dragon/Ground = 1x (not super effective, not resisted)
     - Dragon Claw: Dragon vs Dragon/Ground = 1x
     - Stone Edge: Rock vs Dragon/Ground = 1x (Ground resists Rock? No, Rock is neutral vs Ground)
     - Actually, Rock is neutral vs Ground. Dragon is neutral vs Dragon/Ground.
     
   - Speed: My Garchomp Spe 169 vs their Garchomp Spe 109-169. Could be a tie or I could be slower.
   - If I use Earthquake: 182 Atk, BP 100, neutral vs their Garchomp at 90% HP. With Life Orb (1.3x), that's significant damage.
   - Their Earthquake at 90% HP with Life Orb: their Atk is 135-200. If max 200, that's a lot of damage to my 183 HP.
   
   Actually wait - both have Life Orb. If I switch in Garchomp, their Garchomp will likely use Earthquake again. Let me calculate:
   - Their EQ: Atk ~182 (assuming similar spread), BP 100, neutral, Life Orb 1.3x, vs my Def 115
   - Damage: roughly (182 * 100 / 155) * 1.3 * (100/115) * random ≈ around 100-130 damage to my 183 HP. That's about 55-70% damage. I'd survive.
   
   Then my EQ back: similar damage to their 90% HP (165 HP). I'd deal about 55-70% of their remaining HP.
   
   This is a mirror fight - whoever hits first or has more HP wins. It's risky.
   
   **Metagross vs their Garchomp:**
   - My Metagross: HP 155, Atk 187, Def 150, SpA 103, SpD 112, Spe 134
   - Their Garchomp: at 90% HP, Dragon/Ground
   - Metagross is Steel/Psychic
   - Earthquake vs Steel/Psychic: Ground is 2x vs Steel! That's super effective.
   - Their EQ: Atk ~182, BP 100, 2x vs Steel, Life Orb 1.3x, vs my Def 150
   - Damage: roughly (182 * 100 / 155) * 2 * 1.3 * (100/150) * random ≈ around 150-200 damage to my 155 HP. That could OHKO me!
   
   Wait, let me recalculate more carefully. The damage formula in Pokémon:
   Damage = ((2*Level/5 + 2) * BP * (Atk/Def)) / 50 + 2
   
   At level 50: (2*50/5 + 2) = 22
   EQ: 22 * 100 * (182/150) / 50 + 2 = 22 * 100 * 1.213 / 50 + 2 = 22 * 2.427 + 2 = 53.4 + 2 = 55.4 base
   With 2x STAB? No, Garchomp doesn't have STAB on Ground. Wait, Garchomp IS Ground type, so EQ gets STAB!
   With STAB (1.5x): 55.4 * 1.5 = 83.1
   With Life Orb (1.3x): 83.1 * 1.3 = 108
   With 2x super effective: 108 * 2 = 216
   With random (0.85-1.0): 183-216
   
   My Metagross has 155 HP. So their EQ would deal 183-216 damage, which OHKOes my Metagross (155 HP).
   
   That's terrible. Metagross gets OHKO'd by their Garchomp's Earthquake.
   
   **Garchomp vs their Garchomp:**
   - Their EQ: 22 * 100 * (182/115) / 50 + 2 = 22 * 100 * 1.583 / 50 + 2 = 22 * 3.166 + 2 = 69.7 + 2 = 71.7 base
   - With STAB (1.5x): 71.7 * 1.5 = 107.5
   - With Life Orb (1.3x): 107.5 * 1.3 = 139.8
   - With 1x (neutral, Ground vs Dragon/Ground): 139.8
   - With random: 119-140
   - My Garchomp has 183 HP. So they'd deal about 65-77% damage. I survive.
   
   Then my EQ: 22 * 100 * (182/115) / 50 + 2 = same base = 71.7
   - With STAB (1.5x): 107.5
   - With Life Orb (1.3x): 139.8
   - With 1x: 139.8
   - With random: 119-140
   - Their Garchomp at 90% = 165 HP (if max 183) or up to 193 HP (if max 215)
   - So I'd deal about 62-85% damage.
   
   This is a coin flip in a mirror. But I have the speed advantage potentially (169 vs their 109-169). If I'm faster, I hit first.
   
   Actually, let me reconsider. The opponent is a "scripted control bot." What would it do? It probably has a set strategy. If it leads with Garchomp, it might:
   - Use Earthquake (which it did)
   - Use Swords Dance
   - Use Dragon Claw
   - Use Stone Edge
   
   If I switch in Garchomp, the bot might use EQ again, or it might try to set up. If it uses EQ, we both take damage but I survive and can potentially KO it next turn.
   
   If I switch in Metagross, I get OHKO'd by EQ. Bad.
   
   So Garchomp is the better choice. Let me go with Garchomp.
   
   Actually wait - could the bot use Stone Edge? Rock vs Dragon/Ground: Rock is neutral vs Ground, and Dragon resists Rock? No, Dragon doesn't resist Rock. Rock is neutral vs Dragon/Ground. So Stone Edge would be neutral too.
   
   What about Dragon Claw? Dragon vs Dragon/Ground: Dragon is neutral vs Dragon, and Ground is neutral vs Dragon. So Dragon Claw is neutral.
   
   All of their moves are neutral against my Garchomp. And all my moves are neutral against theirs. It's a pure mirror.
   
   The key question: who hits first? My Spe 169 vs their Spe 109-169. If they're at max speed (169), it's a tie and the bot goes first (in PS, the player who moves first in a tie goes first... actually in PS, if speeds are tied, the player who chose their move first goes first, but since this is a bot, it might be random or the bot goes first).
   
   Actually in Pokémon Showdown, if speeds are tied, the order is random. But the bot is scripted, so it might always go first or last.
   
   Given the risk, let me think about whether there's a better strategy. If I switch in Garchomp and use Earthquake, and the bot uses Earthquake back, we both take ~70% damage. Then next turn, whoever is at lower HP might die to the other's EQ.
   
   Alternatively, if I use Swords Dance, I get +2 Atk, and then next turn my EQ would be much stronger. But the bot might use EQ and bring me to ~30% HP, then I'd need to survive another hit.
   
   Actually, let me recalculate with Swords Dance:
   - After SD: Atk 182 * 2 = 364
   - My EQ: 22 * 100 * (364/115) / 50 + 2 = 22 * 100 * 3.165 / 50 + 2 = 22 * 6.33 + 2 = 139.3 + 2 = 141.3
   - With STAB: 212
   - With Life Orb: 275.6
   - With random: 234-276
   - Their Garchomp at 90% (165 HP): I'd OHKO them easily.
   
   But if I use SD, the bot uses EQ and brings me to ~30% (55 HP). Then next turn, if I use EQ, I OHKO them. But if they use EQ again, they'd deal:
   - 22 * 100 * (182/115) / 50 + 2 = 71.7 * 1.5 * 1.3 = 139.8 * random = 119-140
   - My HP at 55: I'd die.
   
   So SD is risky. If I go EQ first, I deal ~70% damage, they deal ~70% back. Then next turn, I'm at ~30% and they're at ~30%. My EQ would deal ~70% of their remaining 30% = ~21% of max, which isn't enough to KO. Wait, let me recalculate.
   
   After turn 1 (both at ~30%):
   - My HP: 183 * 0.3 = 55
   - Their HP: 165 * 0.3 = 50 (approximately)
   
   My EQ: 119-140 damage. Their HP is 50. I OHKO them!
   Their EQ: 119-140 damage. My HP is 55. I might survive (barely) or die.
   
   So if I go EQ, I likely KO them next turn regardless of who hits first, because my damage (119-140) exceeds their remaining HP (~50).
   
   Wait, but if they hit first (tied speed), they'd deal 119-140 to my 55 HP, and I'd die before I can attack. That's the risk.
   
   Hmm, this is tricky. Let me think about what the bot would do.
   
   The bot is a "scripted control bot." Control bots typically:
   - Set up (Swords Dance, Nasty Plot)
   - Use status moves
   - Use recovery
   - Set up hazards
   
   If the bot is a control bot, it might prefer to use Swords Dance or a status move rather than EQ. But it already used EQ on turn 1. On turn 2, it might:
   - Use EQ again (aggressive)
   - Use Swords Dance (setup)
   - Use Dragon Claw (safe neutral)
   - Use Stone Edge (risky, 80% acc)
   
   If it uses Swords Dance, I can use EQ and deal ~70% damage, then next turn I can KO it.
   If it uses EQ, we both take ~70% damage, and I should KO next turn.
   
   I think Garchomp is the right call. Let me go with Garchomp and use Earthquake.
   
   Wait, I can only choose SWITCH or MOVE. Let me check legal actions:
   1. SWITCH: garchomp
   2. SWITCH: metagross
   
   I can only switch this turn! I can't attack. So I need to choose which Pokémon to switch in.
   
   Given that Metagross gets OHKO'd by EQ, and Garchomp can survive and fight, I should switch in Garchomp.
   
   Let me go with Garchomp.
   

3. Turn 2
   PokéChamp used Dragonclaw
   Qwen3.8 27B used Dragonclaw3,832 tok · 67.4 s · $0.0007

   Mirror matchup. My Garchomp (100% HP) vs their Garchomp (90% HP, Life Orb). Dragon Claw is 2x SE (160 effective BP) with STAB+LO - should KO their Garchomp. If I survive their EQ (they'll likely use it), I face their 2nd pick (gengar/alakazam/metagross/skarmory/gliscor). Metagross is bad vs EQ (2x SE). Plan: KO their Garchomp with Dragon Claw, then adapt.

   Reasoning trace (650 words)

   Let me analyze the situation:
   
   - My Garchomp is at 100% HP (183/183)
   - Opponent's Garchomp is at 90% HP (took Life Orb recoil from EQ last turn)
   - Both have Life Orb
   - My Garchomp has Rough Skin (contact damage)
   - Opponent's Garchomp ability is unknown (could be Sandveil or Rough Skin)
   
   Key considerations:
   - If I use EQ: 100 BP Ground move, neutral on Garchomp (Dragon/Ground). With Life Orb (1.3x), this should deal significant damage. Their Garchomp is at 90% HP. Let me estimate: EQ base 100, Life Orb 1.3x. Against a Garchomp with ~107 SpD... wait, this is physical. Against their Def (103-161 range). 
   
   Actually, let me think about this differently. Last turn, their EQ (with Life Orb) hit my Alakazam and fainted it. Alakazam had 130 HP. So their EQ with Life Orb dealt 130+ damage to a Psychic-type (neutral).
   
   My Garchomp has 183 HP and 115 Def. Their EQ would deal less to my Garchomp than to Alakazam. Let me estimate: if their EQ dealt ~130 damage to Alakazam (130 HP, 85 Def), then against Garchomp (183 HP, 115 Def) it would deal roughly 130 * (85/115) ≈ 96 damage. So my Garchomp would survive their EQ.
   
   If I use EQ back: my EQ with Life Orb against their Garchomp (90% HP, so ~165-193 HP remaining). Their Def is 103-161. Let's say around 115-130. My EQ would deal roughly similar damage to what theirs did to Alakazam, adjusted for their higher Def. Maybe around 100-120 damage. That would likely KO their Garchomp at 90% HP (165-193 HP).
   
   Actually, let me reconsider. Their Garchomp is at 90% of its max HP. If max HP is 183, that's ~165 HP. If max HP is 215, that's ~194 HP.
   
   My EQ with Life Orb: Base 100, STAB (Dragon/Ground using Ground move - yes, STAB 1.5x), Life Orb 1.3x. So multiplier is 1.5 * 1.3 = 1.95.
   
   Against their Garchomp's Def (let's say ~115-130):
   Damage ≈ (2*50/50+2) * 100 * 1.95 * (182/Def) / 8 + 2
   With Def 115: ≈ 2.04 * 100 * 1.95 * (182/115) / 8 + 2 ≈ 2.04 * 195 * 1.583 / 8 + 2 ≈ 78.8 / 8 + 2... 
   
   This is getting complicated. Let me just think strategically.
   
   The key question: Should I use EQ, Dragon Claw, Swords Dance, or switch?
   
   - EQ: Neutral damage, likely KOs their Garchomp at 90% HP. Risk: they also use EQ and I take damage but survive.
   - Dragon Claw: Super effective (2x) on Dragon/Garchomp. 80 BP but 2x SE = 160 effective BP. With STAB and Life Orb, this is very strong. Likely KOs their Garchomp.
   - Swords Dance: +2 Attack. Then next turn I can sweep. But they might set up or switch.
   - Switch to Metagross: They have EQ which is 2x SE on Metagross. Bad idea.
   
   Dragon Claw seems best: super effective, likely KOs their Garchomp at 90% HP. Even if they switch, I've done good damage.
   
   Actually wait - if I use Dragon Claw and KO their Garchomp, then I face one of their other 2 Pokémon (from gengar, alakazam, metagross, skarmory, gliscor). 
   
   If I use EQ and KO, same thing.
   
   Dragon Claw has higher effective power (80 * 2 = 160 vs 100 * 1 = 100), so it's more likely to KO. Let me go with Dragon Claw.
   
   Actually, let me reconsider Swords Dance. If I Swords Dance, I get +2 Attack. Then next turn, my EQ or Dragon Claw would be devastating. But the risk is they might switch to something that can hurt me, or they might also set up.
   
   Given that their Garchomp is at 90% and I can likely KO it this turn with Dragon Claw (super effective), I think the best play is to KO it now and then deal with whatever they send in.
   
   Let me go with Dragon Claw.

   Mirror matchup. My Garchomp (143/183 HP, Life Orb) vs their Metagross (100% HP). I outspeed (169 vs 81-134). EQ is 2x SE + STAB + LO on Steel - estimated 164-216 dmg vs 155-187 HP, likely OHKO. If it survives, their EQ would OHKO me, so I'd switch to my Metagross. Their 3rd pick (gengar/alakazam/skarmory/gliscor) still unknown.

   Reasoning trace (962 words)

   Let me analyze the situation:
   
   - My Garchomp is at 143/183 HP (78.1%) with Life Orb
   - Opponent's Metagross is at 100% HP
   - I outspeed Metagross (169 vs 81-134)
   - Metagross is Steel/Psychic
   
   Key considerations:
   - Earthquake is 2x super effective on Metagross (Steel). With my Garchomp's 182 Atk + Life Orb, this should deal massive damage. Let me estimate: EQ base 100, 2x SE, STAB (Ground on Dragon/Ground), Life Orb 1.3x. That's a lot of damage. Metagross has 155-187 HP. This could potentially OHKO or at least heavily damage Metagross.
   - If I use EQ, I take Life Orb recoil (1/10 of 183 = ~18 HP). I'm at 143, so I'd be at ~125 after recoil.
   - Metagross could use EQ back (2x SE on my Garchomp - Ground on Dragon/Ground). That would be devastating. Or it could use Zen Headbutt, Bullet Punch, or Stealth Rock.
   - If Metagross has Stealth Rock, that's a setup move. If it has EQ, that's a threat.
   - Bullet Punch has priority, so even though I'm faster, Bullet Punch would hit first.
   
   Strategy: I should use Earthquake to deal maximum damage to Metagross. It's 2x SE and with STAB + Life Orb, it should do significant damage. Even if Metagross survives and hits back with EQ, I can switch to my Metagross.
   
   Actually, let me think about whether to switch to my Metagross instead. My Metagross is at 100% HP and can use Stealth Rock for setup. But if I switch, I give up the turn and their Metagross gets a free move. Also, my Garchomp can potentially OHKO or heavily damage their Metagross with EQ.
   
   Let me calculate EQ damage more carefully:
   - Garchomp Atk: 182
   - EQ Base Power: 100
   - STAB: 1.5x (Ground on Dragon/Ground)
   - SE: 2x (Ground on Steel)
   - Life Orb: 1.3x
   - Metagross Def: 135-200 (let's say around 150-175 for a typical spread)
   
   Damage formula (simplified): ((2*50/5+2) * 100 * 182 * 1.5 * 2 * 1.3) / (15 * Metagross_Def) + 2
   = ((22) * 100 * 182 * 1.5 * 2 * 1.3) / (15 * Def) + 2
   = (22 * 100 * 182 * 3.9) / (15 * Def) + 2
   = (22 * 100 * 182 * 3.9) / (15 * Def) + 2
   = (1,562,760) / (15 * Def) + 2
   
   If Def = 150: 1,562,760 / 2,250 + 2 = 694 + 2 = 696... that seems way too high. Let me recalculate.
   
   Actually the formula is: ((2*Level/5 + 2) * Power * A / D) / 50 + 2
   = ((2*50/5 + 2) * 100 * 182 / Def) / 50 + 2
   = ((20 + 2) * 100 * 182 / Def) / 50 + 2
   = (22 * 100 * 182 / Def) / 50 + 2
   = (400,400 / Def) / 50 + 2
   = 8,008 / Def + 2
   
   Then multiply by modifiers: STAB (1.5) * SE (2) * Life Orb (1.3) = 3.9
   
   So: (8,008 / Def + 2) * 3.9
   
   If Def = 150: (53.4 + 2) * 3.9 = 55.4 * 3.9 = 216
   If Def = 175: (45.8 + 2) * 3.9 = 47.8 * 3.9 = 186
   If Def = 200: (40 + 2) * 3.9 = 42 * 3.9 = 164
   
   Metagross HP: 155-187
   
   So EQ would deal 164-216 damage to a Metagross with 155-187 HP. This means EQ likely OHKOs their Metagross!
   
   Even in the worst case (Def 200, HP 187): 164 damage to 187 HP = not quite OHKO but very close.
   In the best case (Def 150, HP 155): 216 damage to 155 HP = OHKO.
   
   Most likely it's an OHKO or very close. I should use Earthquake.
   
   After EQ, I take Life Orb recoil: 1/10 of 183 = ~18 HP. So I'd be at ~125 HP.
   
   If their Metagross survives and hits back:
   - If it uses EQ (2x SE on me): ((22 * 100 * Atk / 115) / 50 + 2) * 1.5 * 2 * 1.3
     Their Atk: 139-205. Let's say 170.
     = (22 * 100 * 170 / 115) / 50 + 2 = (374,000 / 115) / 50 + 2 = 3,252 / 50 + 2 = 65 + 2 = 67
     * 3.9 = 261 damage. My Garchomp has 125 HP. That's an OHKO.
     
   - If it uses Zen Headbutt (Psychic, 80 BP, not very effective on Dragon/Ground... wait, Psychic is not very effective on Steel but neutral on Dragon/Ground):
     Actually Psychic is neutral on Dragon/Ground. So: ((22 * 80 * 170 / 115) / 50 + 2) * 1.3 (if LO)
     = (299,200 / 115) / 50 + 2 = 2,602 / 50 + 2 = 52 + 2 = 54 * 1.3 = 70. I'd survive.
   
   - If it uses Bullet Punch (priority, 40 BP, Steel, not very effective on Dragon/Ground... wait, Steel is not very effective on Dragon/Ground? Let me check. Steel moves are not very effective on Dragon? No, Steel is neutral on Dragon. Steel is not very effective on Steel, Fire, Electric, Water. So Steel is neutral on Dragon/Ground.
     = ((22 * 40 * 170 / 115) / 50 + 2) * 1.3 = (149,600 / 115) / 50 + 2 = 1,301 / 50 + 2 = 26 + 2 = 28 * 1.3 = 36. I'd survive.
   
   - If it uses Stealth Rock: no damage to me, but sets up hazards.
   
   So the main risk is if their Metagross has EQ and uses it. But if my EQ OHKOs their Metagross, there's no risk.
   
   Given the high probability of OHKO, I should use Earthquake. If it doesn't OHKO, I can switch to my Metagross next turn.
   
   Let me go with Earthquake.

   My Garchomp at 20 HP faces Gengar at 100%. Opponent has used all 3 Pokémon (Garchomp, Metagross fainted; Gengar active). EQ is 2x SE on Ghost/Poison with STAB+LO — should OHKO Gengar. If I go first (169 Spe), I win immediately. If Gengar goes first and KOs me, Metagross comes in at 100% and KOs Gengar next turn. Either way I win. EQ is the only viable option.

   Reasoning trace (1,643 words)

   Let me analyze the situation:
   
   My Garchomp is at 20/183 HP (10.9%) - very low. The opponent has Gengar at 100% HP.
   
   Key considerations:
   - My Garchomp is at 20 HP. If Gengar hits me with anything, I'll likely faint.
   - Gengar is Ghost/Poison. Earthquake is super effective (2x) on it.
   - Garchomp's Earthquake with Life Orb: Base 100, 2x SE, STAB (1.5x), Life Orb (1.3x). That's a lot of damage.
   - Gengar's HP range: 135-167. My EQ would deal significant damage.
   - But Gengar could hit me back and KO me at 20 HP.
   
   Let me think about what Gengar might do:
   - Gengar has Cursed Body (30% chance to disable a move on contact... wait, that's for physical moves that make contact. Actually Cursed Body triggers when hit by a move, not just contact moves. Let me reconsider - Cursed Body: "If this Pokémon is hit by a move, there is a 30% chance that move gets disabled." So any move that hits Gengar could be disabled.)
   - Gengar's possible moves: Since it's a copy of my team's Gengar... wait, no. The opponent's team is an exact copy of MY team. My team is Garchomp, Alakazam, Metagross. But the opponent's team preview shows Garchomp, Gengar, Alakazam, Metagross, Skarmory, Gliscor.
   
   Wait, let me re-read: "Your opponent is PokéChamp, a scripted control bot, not a language model. Its six are an exact copy of your team: the same Pokémon, items, abilities, moves and stat spreads."
   
   But my team is Garchomp, Alakazam, Metagross. The opponent's team preview shows 6 Pokémon: Garchomp, Gengar, Alakazam, Metagross, Skarmory, Gliscor. That's different from my team. Let me re-read...
   
   Oh wait, I think the "exact copy" means the opponent has the same pool of Pokémon available, but they chose different ones. Actually no - "Its six are an exact copy of your team" - but my team only has 3 Pokémon (Garchomp, Alakazam, Metagross). The opponent has 6 different ones. This is confusing.
   
   Actually, re-reading: "one Pokémon on the field per side; each player brought 3 of their 6 Pokémon" - so each player has a team of 6, and brings 3. My team of 6 must include Garchomp, Alakazam, Metagross (the ones I have) plus 3 others I haven't seen. The opponent's team of 6 is Garchomp, Gengar, Alakazam, Metagross, Skarmory, Gliscor.
   
   Wait, but it says "Its six are an exact copy of your team: the same Pokémon, items, abilities, moves and stat spreads." So my team of 6 should be the same as the opponent's team of 6. But I only see 3 of my Pokémon listed. Maybe the other 3 are Gengar, Skarmory, Gliscor? That would make sense - my full team is Garchomp, Alakazam, Metagross, Gengar, Skarmory, Gliscor, and I brought Garchomp, Alakazam, Metagross. The opponent brought Garchomp, Metagross, Gengar.
   
   OK so the opponent's Gengar is the same as my Gengar (which I have but didn't bring). Its moves would be the same as what my Gengar would have. But I don't know what moves my Gengar has since it's not listed in my active team.
   
   Anyway, the key question: what should I do with my Garchomp at 20 HP facing Gengar at 100%?
   
   Options:
   1. Earthquake - 2x SE on Gengar. With STAB + LO, this could be a huge hit. Let me estimate: Garchomp Atk 182, Gengar Def 72-123. EQ base 100, 2x SE, 1.5x STAB, 1.3x LO. Damage formula roughly: (2 * 182 * 100 / 150 + 2) * 2 * 1.5 * 1.3 * (72-123/182+2... let me just estimate.
   
   Actually, let me think more simply. My Garchomp's EQ on their Garchomp (Dragon/Ground, 2x SE) dealt enough to KO a 90% HP Garchomp. Gengar has lower Def (72-123 vs Garchomp's 103-161) and lower HP (135-167 vs 183-215). So EQ should definitely OHKO Gengar.
   
   But the risk: Gengar moves first or second? Speed: my Garchomp 169 vs Gengar 117-178. Could go either way.
   
   If Gengar moves first: Gengar could use a move that KOs my 20 HP Garchomp. Gengar is a special attacker (SpA 135-200). It could use Shadow Ball, Sludge Bomb, Psychic, Focus Blast, etc. Any of these would likely KO my Garchomp at 20 HP.
   
   If I move first: EQ KOs Gengar, and I survive (barely, at 20 - 18 = 2 HP from LO recoil).
   
   So the strategy: I should use Earthquake and hope I go first. If I go first, I KO Gengar and win (my Metagross is at 100% and can clean up... wait, the opponent has no more Pokémon! They brought 3: Garchomp, Metagross, Gengar. All three are now fainted or about to be. If I KO Gengar, I win the match!)
   
   Wait, let me check: Opponent brought Garchomp (fainted), Metagross (fainted), Gengar (active at 100%). If I KO Gengar, the opponent has no more Pokémon and I win!
   
   So I MUST KO Gengar this turn. Earthquake is the best option - 2x SE, should definitely OHKO.
   
   The risk is if Gengar goes first and KOs me. But if I don't attack, Gengar will definitely KO me next turn. So Earthquake is my best (and really only) option.
   
   Actually, should I consider switching to Metagross? Metagross at 100% HP vs Gengar. Gengar is Ghost/Poison. Metagross is Steel/Poychic. Gengar's moves would likely be special (Shadow Ball, Sludge Bomb, etc.). Metagross has good SpD (112). But Gengar could still hit hard. And Metagross's EQ would also be 2x SE on Gengar.
   
   But if I switch, Gengar gets a free turn to attack my Garchomp (KO it at 20 HP) or set up. Then I'd have Metagross vs Gengar. That's a worse position than trying to KO Gengar now.
   
   Actually wait - if I switch, does Gengar attack the Garchomp or the Metagross? In Pokémon, when you switch, the incoming Pokémon is the target. So Gengar would attack Metagross. Metagross at 100% HP could survive a Gengar hit (probably). Then next turn Metagross EQs Gengar (2x SE).
   
   But the risk with switching: Gengar might have a move that does significant damage to Metagross, or Cursed Body might disable my EQ. Also, Gengar might use a setup move.
   
   I think the best play is to use Earthquake and hope for the speed roll. My Garchomp is 169 speed, Gengar is 117-178. If Gengar is at the lower end of speed, I go first and win. If Gengar is faster, I lose.
   
   Alternatively, Stone Edge: Rock is not super effective on Ghost/Poison (Ghost resists Rock? No - Ghost is immune to Normal and Fighting, resists Poison and Bug. Rock is neutral on Ghost and neutral on Poison. So Stone Edge would be neutral, not super effective. Earthquake is 2x SE. Definitely EQ.
   
   Dragon Claw: Dragon is neutral on Ghost/Poison. Not as good as EQ.
   
   Swords Dance: Waste of a turn, I'm at 20 HP.
   
   So Earthquake is the clear choice. Let me go with that.
   
   Actually, one more thought: should I switch to Metagross to be safe? If I switch:
   - Gengar attacks Metagross (probably survives, Metagross has 155 HP and good defenses)
   - Next turn, Metagross EQs Gengar (2x SE, should KO)
   - I win with Metagross at reduced HP
   
   If I stay and EQ:
   - 50/50 (roughly) speed check
   - If I go first: KO Gengar, win immediately
   - If Gengar goes first: Gengar KOs my Garchomp, I lose (well, I still have Metagross, but Gengar is at 100% and I'd be starting fresh... actually no, if Gengar KOs my Garchomp, I switch to Metagross, and then it's Metagross vs Gengar. Same as the switch scenario but I lost a turn.)
   
   Hmm, actually if Gengar KOs my Garchomp, I get to switch to Metagross for free (the switch happens after the KO). So it's:
   - Gengar KOs Garchomp → I switch to Metagross → Gengar at 100% vs Metagross at 100%
   - Next turn: Metagross EQs Gengar → Win
   
   vs. switching now:
   - Gengar attacks Metagross → Metagross at reduced HP
   - Next turn: Metagross EQs Gengar → Win
   
   The switch now is slightly safer because Metagross takes the hit at 100% rather than risking Garchomp fainting (which it will anyway at 20 HP). But actually, if Garchomp faints, I still get to bring in Metagross. The difference is:
   - Switch now: Metagross takes 1 hit from Gengar, then KOs Gengar next turn
   - Stay and lose speed: Garchomp faints, Metagross comes in at 100%, takes 0 hits from Gengar (Gengar already used its move on Garchomp), then KOs Gengar next turn
   
   Wait, that's actually better! If Garchomp faints to Gengar's attack, Gengar has already used its move. Then Metagross comes in fresh at 100% and KOs Gengar next turn. Whereas if I switch now, Gengar gets to hit Metagross.
   
   So staying and using EQ is actually the best play:
   - If I go first: Win immediately
   - If Gengar goes first: Gengar KOs Garchomp, Metagross comes in at 100%, KOs Gengar next turn. Win.
   
   Either way I win! The only question is whether I win this turn or next turn. And there's a small risk that Gengar's move doesn't KO my Garchomp (unlikely at 20 HP, but possible if it's a weak move or has low accuracy). In that case, I'd be at very low HP and could still try to EQ.
   
   Actually, the main risk with staying: what if Gengar has a move that doesn't make contact and Cursed Body doesn't trigger, and it's a very strong move? At 20 HP, almost anything KOs me. But that's fine because I still win.
   
   The only scenario where staying is bad: Gengar has a move that KOs my Garchomp AND somehow also prevents me from winning with Metagross. Like if Gengar has a move that does massive damage to Metagross too... but Gengar only gets one move per turn.
   
   I'm confident: MOVE: earthquake. This is the optimal play.

   My Metagross (155 HP, 100%) faces their Gengar (100%). EQ is 2x SE on Ghost/Poison, ~168 dmg vs 135-167 HP — should OHKO. Even if Gengar goes first (Spe up to 178), Shadow Ball only does ~42 to my 155 HP. Cursed Body 30% disables EQ but I still deal damage this turn. All 3 opponent Pokémon accounted for (Garchomp, Metagross fainted; Gengar active). Win this and I'm done.

   Reasoning trace (1,254 words)

   Let me analyze the situation:
   
   - My Metagross is at 100% HP (155/155) facing their Gengar at 100% HP.
   - My Metagross has: Earthquake (2x SE on Ghost/Poison), Zen Headbutt (2x SE on Ghost/Poison), Bullet Punch (priority +1), Stealth Rock.
   - Gengar has Cursed Body (30% chance to disable move on hit).
   - Speed: My Metagross 134 vs Gengar 117-178. Could go either way.
   
   Key considerations:
   1. Earthquake is 2x SE on Ghost/Poison with STAB (Steel/Psychic... wait, no. Metagross is Steel/Psychic. Earthquake is Ground type. So no STAB. But it's 2x SE on Ghost/Poison.
      - Actually wait, Gengar is Ghost/Poison. Ground is 2x effective on both Ghost and Poison? No. Ground is 2x on Poison, and Ground is 2x on... let me think. Ghost/Poison: Ground is 2x on Poison, and Ground is 2x on... no. Ground is 2x on Poison, Rock, Steel, Fire, Electric. Ground is 2x on Ghost? No, Ground is 2x on Poison, Rock, Steel, Fire, Electric. Ground is not super effective on Ghost. Wait, actually Ground IS super effective on Ghost? No! Ghost is immune to Normal and Fighting. Ground is NOT super effective on Ghost.
      
      Let me reconsider. Gengar is Ghost/Poison.
      - Ground vs Ghost: neutral (1x)
      - Ground vs Poison: 2x
      - So Ground vs Ghost/Poison: 2x total
      
      Yes, Earthquake is 2x SE on Gengar.
   
   2. Zen Headbutt is Psychic type. Psychic vs Ghost: 0x (Ghost is immune to Psychic!). Wait no, Psychic is not super effective on Ghost. Actually, Psychic is NOT effective against Ghost at all? No wait - Psychic is not immune to Ghost, but Ghost is immune to Normal and Fighting. Psychic vs Ghost is... let me think. Ghost resists Poison and Bug. Ghost is weak to Ghost and Dark. Psychic is not super effective on Ghost. Actually, I think Psychic vs Ghost is neutral (1x). Wait no - Ghost is immune to Normal and Fighting only. Psychic vs Ghost should be neutral.
   
      Actually wait, let me reconsider. The type chart:
      - Psychic is super effective on Fighting and Poison
      - Psychic is not very effective on Steel and Psychic
      - Ghost is immune to Normal and Fighting
      
      So Psychic vs Ghost/Poison: Psychic is 2x on Poison, 1x on Ghost = 2x total.
      
      So Zen Headbutt is also 2x SE on Gengar.
   
   3. Bullet Punch is Steel type, priority +1. Steel vs Ghost/Poison: Steel is 1x on Ghost, 1x on Poison = 1x. Not super effective. But it has priority +1, so it always goes first.
   
   4. Stealth Rock: sets up hazards. Gengar is Ghost/Poison, so Rock is 1x on Ghost, 1x on Poison = 1x. Not very useful against Gengar specifically, but could hurt future switch-ins.
   
   Now, the key question: Can I KO Gengar?
   
   My Metagross: Atk 187, no item boost (no Life Orb mentioned for my Metagross... wait, let me check. My Metagross has metagrossite as item. So no Life Orb.)
   
   Earthquake: 100 BP, 2x SE, no STAB (Ground on Steel/Psychic). 
   - Base damage: 187 Atk * 100 BP * 2 (SE) / 50 + 2 = 187*100*2/50 + 2 = 748 + 2 = 750... wait let me use the proper formula.
   - Damage = ((2*Level/5+2) * BP * A/D) / 50 + 2
   - Level 50: (2*50/5+2) = 22
   - 22 * 100 * (187/Def) / 50 + 2
   - Gengar Def: 72-123. Let's say around 100 (mid-range).
   - 22 * 100 * 187/100 / 50 + 2 = 22 * 187 / 50 + 2 = 4114/50 + 2 = 82.28 + 2 = 84.28
   - With 2x SE: 84.28 * 2 = 168.56
   - Gengar HP: 135-167. So 168 damage would likely OHKO Gengar (135-167 HP range).
   
   Actually wait, I need to be more careful. The SE multiplier is already included in the calculation. Let me redo:
   - Damage = ((2*50/5+2) * 100 * (187/Def)) / 50 + 2, then multiply by SE (2x)
   - = (22 * 100 * 187/Def) / 50 + 2, then * 2
   - If Def = 100: (22 * 100 * 1.87) / 50 + 2 = 4114/50 + 2 = 82.28 + 2 = 84.28, * 2 = 168.56
   - If Def = 72: (22 * 100 * 187/72) / 50 + 2 = (22 * 259.7) / 50 + 2 = 5713.4/50 + 2 = 114.27 + 2 = 116.27, * 2 = 232.5
   - If Def = 123: (22 * 100 * 187/123) / 50 + 2 = (22 * 152) / 50 + 2 = 3344/50 + 2 = 66.88 + 2 = 68.88, * 2 = 137.76
   
   So Earthquake deals roughly 138-233 damage to Gengar (135-167 HP). This should OHKO in most cases, but if Gengar has high Def and high HP, it might not.
   
   Zen Headbutt: 80 BP, 2x SE (Psychic on Poison), 90% accuracy, 20% flinch.
   - Damage = (22 * 80 * 187/Def) / 50 + 2, then * 2
   - If Def = 100: (22 * 80 * 1.87) / 50 + 2 = 3291.2/50 + 2 = 65.82 + 2 = 67.82, * 2 = 135.65
   - If Def = 72: (22 * 80 * 187/72) / 50 + 2 = (22 * 207.8) / 50 + 2 = 4571.6/50 + 2 = 91.43 + 2 = 93.43, * 2 = 186.86
   - If Def = 123: (22 * 80 * 187/123) / 50 + 2 = (22 * 121.6) / 50 + 2 = 2675.2/50 + 2 = 53.5 + 2 = 55.5, * 2 = 111
   
   Zen Headbutt deals roughly 111-187 damage. Less reliable than Earthquake.
   
   Bullet Punch: 40 BP, 1x (not SE), priority +1.
   - Damage = (22 * 40 * 187/Def) / 50 + 2
   - If Def = 100: (22 * 40 * 1.87) / 50 + 2 = 1645.6/50 + 2 = 32.91 + 2 = 34.91
   - Very low damage, won't KO.
   
   So the best option is Earthquake. It's 2x SE, 100% accuracy, and should OHKO Gengar in most stat rolls.
   
   But wait - Cursed Body! 30% chance the move gets disabled. If Earthquake gets disabled, I can't use it again. But I still deal damage this turn.
   
   Also, speed concern: My Metagross is 134 Spe, Gengar is 117-178. If Gengar is faster (up to 178), it could attack first. Gengar's revealed move is Shadow Ball (Ghost, 80 BP). Shadow Ball vs Metagross (Steel/Psychic): Ghost is 1x on Steel, 1x on Psychic = 1x. Not very effective.
   
   Shadow Ball damage: Gengar SpA 135-200, let's say ~170.
   - (22 * 80 * 170/150) / 50 + 2 = (22 * 80 * 1.133) / 50 + 2 = 1994.7/50 + 2 = 39.9 + 2 = 41.9
   - Metagross has 155 HP, so Shadow Ball does about 42 damage. Not a KO.
   
   Even if Gengar goes first and hits with Shadow Ball, my Metagross survives (155-42 = 113 HP) and then Earthquake KOs Gengar.
   
   If I go first (134 > 117), Earthquake KOs Gengar before it can attack.
   
   Either way, Earthquake wins. The only risk is Cursed Body disabling Earthquake, but I still deal damage this turn.
   
   Actually, should I consider Mega Evolving? Wait, the legal actions don't show a [MEGA] option. Let me check... The legal actions are:
   1. MOVE: earthquake
   2. MOVE: zenheadbutt
   3. MOVE: bulletpunch
   4. MOVE: stealthrock
   
   No MEGA option listed. And the status says "Mega Evolution available: No". So I can't Mega Evolve. That's fine, my Metagross is already strong enough.
   
   I'll go with Earthquake. It's the most reliable KO option.
