    This is a mirror match — the opponent has the exact same six Pokémon. The strongest, most versatile core is Dragapult (fastest at 213, Cursed Body, Ghost coverage vs Fighting/Poison), Gholdengo (defensive anchor with Good as Gold and Steel/Ghost typing), and Garchomp (physical wallbreaker with Earthquake vs Steel/Rock). This gives strong offensive pressure plus a defensive pivot.

    This is a team preview turn in Champions Singles (bring 3 of 6). I need to choose the best 3 Pokémon to bring.
    
    Let me analyze my team and the opponent's team.
    
    MY TEAM:
    1. Dragapult (Dragon/Ghost) - Scarf, Cursed Body, Spe 213. Fast special attacker. Shadowball, Dracometeor, U-turn, Thunderbolt.
    2. Garchomp (Dragon/Ground) - Leftovers, Rough Skin, Spe 169. Physical wallbreaker. Dragon Claw, Earthquake, Stone Edge, Swords Dance.
    3. Gholdengo (Steel/Ghost) - Focus Sash, Good as Gold, Spe 104. Poltergeist, Shadowball, Flash Cannon, Nasty Plot.
    4. Corviknight (Flying/Steel) - Sitrus, Mirror Armor, Spe 87. Defog, Roost, Iron Head, U-turn.
    5. Sneasler (Fighting/Poison) - Expert Belt, Unburden, Spe 189. Dire Claw, Swords Dance, Close Combat, Poison Jab.
    6. Quaquaval (Water/Fighting) - Life Orb, Moxie, Spe 137. Aqua Step, Hydro Cannon, Close Combat, Ice Spinner.
    
    OPPONENT'S TEAM:
    - Dragapult
    - Garchomp
    - Gholdengo
    - Corviknight
    - Sneasler
    - Quaquaval
    
    So the opponent has the exact same team as me! This is a mirror match essentially (same 6 Pokémon available to both).
    
    In a mirror match situation, I need to think about what gives me the best matchup. Since both teams are identical, the key is to pick a core that has good synergy and can handle the threats.
    
    Let me think about the best 3-pick.
    
    The opponent has all 6 of my Pokémon available, so they could bring any 3.
    
    Key considerations:
    - Dragapult is very fast (213) and a great offensive threat with Cursed Body.
    - Garchomp is a strong physical wallbreaker.
    - Sneasler is fast and can set up Swords Dance.
    - Gholdengo is a great defensive/offensive pivot.
    - Corviknight is a defensive wall.
    - Quaquaval is a setup sweeper.
    
    In a mirror match, I want to pick a balanced core. Let me think about what's most valuable.
    
    Dragapult is probably the best pick - it's the fastest and can threaten with Cursed Body stalling moves.
    
    Gholdengo is excellent defensively with Steel/Ghost typing and Good as Gold immunity to status.
    
    Garchomp is a strong wallbreaker.
    
    Let me think about the matchups. Since the opponent has the same team, I need to consider:
    - What do I need to beat?
    - What threats do I cover?
    
    The opponent's team likely includes: Dragapult, Garchomp, Gholdengo, Sneasler, Corviknight, Quaquaval.
    
    My best picks should give me:
    1. A fast offensive threat (Dragapult)
    2. A defensive anchor (Gholdengo or Corviknight)
    3. A wallbreaker or sweeper
    
    Let me think about the strongest core.
    
    Dragapult + Gholdengo + Garchomp would be a strong offensive core.
    - Dragapult handles Fighting types (Sneasler, Quaquaval) via Ghost moves and is immune to Fighting.
    - Gholdengo resists Rock, Ice, Steel, and is immune to Poison and Normal.
    - Garchomp handles Steel types (Corviknight, Gholdengo) with Earthquake.
    
    Actually, let me reconsider. In a mirror match, the key matchups matter.
    
    Dragapult is immune to Fighting and Poison, resists Dragon. It's super fast. It beats Sneasler and Quaquaval easily.
    
    Gholdengo is immune to Poison and Normal, resists Steel, Rock, Ice. Good as Gold means status immunity.
    
    Garchomp is a physical tank.
    
    Let me think about what the opponent might bring and how I match up.
    
    If opponent brings Dragapult, Garchomp, Gholdengo:
    - My Dragapult vs their Dragapult: speed tie, Ghost moves.
    - My Garchomp vs their Gholdengo: Earthquake beats Gholdengo? Gholdengo is Steel/Ghost, immune to Poison/Normal. Earthquake hits Steel super effectively. Actually Garchomp Earthquake 2x vs Steel. But Gholdengo has Focus Sash. Hmm.
    - My Gholdengo vs their Garchomp: Gholdengo resists Dragon, can take a Dragon Claw.
    
    This is getting complex. Let me just pick the strongest, most versatile core.
    
    I think Dragapult + Garchomp + Gholdengo is a strong core. But let me consider the defensive side.
    
    Actually, in these mirror matches, having a fast pivot and a setup sweeper is key. Let me think about Sneasler.
    
    Sneasler with Unburden and Swords Dance is a powerful sweeper. But it's frail.
    
    Let me go with a balanced approach:
    - Dragapult (fast attacker, handles Fighting/Poison)
    - Gholdengo (defensive pivot, good typing)
    - Garchomp (wallbreaker, handles Steel/Rock)
    
    This gives me offensive pressure and defensive utility.
    
    Alternatively:
    - Dragapult
    - Gholdengo
    - Corviknight (defensive)
    
    But I think the offensive core is stronger.
    
    Let me go with Dragapult, Garchomp, Gholdengo.
    
    Wait, let me reconsider. The opponent has the same team. If I bring Dragapult, Garchomp, Gholdengo, the opponent could bring Corviknight, Sneasler, Quaquaval which would give them a good matchup against my team.
    
    Actually, I can't perfectly predict the opponent. Let me just pick the best 3 based on overall team value.
    
    Dragapult is clearly the best - fastest, best coverage, Cursed Body.
    Gholdengo is second best - great typing, Good as Gold, Focus Sash.
    Garchomp is third - strong wallbreaker.
    
    Sneasler is also good but frail.
    Corviknight is defensive but slow.
    Quaquaval is a setup sweeper but needs setup time.
    
    I'll go with Dragapult, Garchomp, Gholdengo.
    
    Actually, let me reconsider the whole thing. This is a mirror match, so the opponent will likely have a similar core. The key is to have the best individual Pokémon and good synergy.
    
    Dragapult: 213 speed, can outspeed everything except maybe nothing. Great.
    Gholdengo: defensive anchor.
    Garchomp: physical breaker.
    
    I'm confident in Dragapult, Garchomp, Gholdengo.
    
    Let me finalize.

    Goldengo is 4x weak to Ghost and Dragapult is far faster, so Shadowball will knock it out cleanly before it can act. Dracometeor is not very effective and cripples Dragapult's SpA, so Shadowball is clearly best.

    Reasoning trace (142 words)
    Goldengo is Ghost/Steel. It's weak to Ghost (4x? Let me think). Goldengo is Ghost/Steel. Weaknesses: Ghost is super effective. Ghost/Steel: Ghost weak to Ghost, Dark, Bug. Steel weak to Fire, Fighting, Ground. Combined: Ghost/Steel is 4x weak to Ghost? Ghost hits Steel neutrally, and Ghost is super effective against Ghost. So 2x * 2x = 4x. Yes, 4x weak to Ghost.
    
    Shadowball is Ghost, super effective, and would be 4x. Dragapult is faster (213 vs max 149). Shadowball at 80 BP with 4x effectiveness should knock out Goldengo easily. Dracometeor is not very effective (Steel resists Dragon) and lowers SpA by 2.
    
    So Shadowball is the clear choice - it knocks out Goldengo before it moves. No need for U-turn since we have a clean KO and can just keep Dragapult in or switch. Actually, knocking out is the priority. Shadowball.

    Dragapult is much faster and Shadow Ball is super effective, almost certainly knocking out Gholdengo at 52%. No reason to switch when we're ahead in the exchange.

    Reasoning trace (36 words)
    Dragapult is faster and Shadow Ball is super effective, likely to knock out Gholdengo at 52%. Switching to Garchomp or Gholdengo would be premature since we're winning the exchange. Shadow Ball is the clear choice.
    
    Chimps at the Zoo switched to Sneasler

    Chimps at the Zoo switched to Quaquaval
    Ornith 1.5 35B used Shadowball1,912 tok · 11.8 s

    Sneasler's Fighting/Poison STAB moves are completely ineffective against Ghost-dragapult, which is faster and can Shadow Ball it out safely (super effective). No reason to switch.

    Reasoning trace (182 words)
    Sneasler is a Fighting/Poison type. Dragapult is Dragon/Ghost. Ghost moves are immune to Fighting, and Sneasler's STAB Fighting moves won't hit Dragapult. Sneasler's Poison moves... Dragapult is not weak to Poison. So Dragapult is completely safe against Sneasler.
    
    Sneasler's possible moves: it's a physical attacker with high ATK. It likely has Swords Dance + High Horsepower/Close Combat, or Throat Chop. But since Dragapult is immune to Fighting and resistant/immune to Poison... actually Ghost is immune to Poison? No, Ghost is not immune to Poison. Wait, Poison is not very effective against Ghost? Actually Ghost is immune to Poison. Yes, Ghost-type Pokémon are immune to Poison-type moves.
    
    So Sneasler's only reliable damage would be if it has a non-Fighting/Poison move. But its STAB moves (Fighting/Poison) are completely ineffective against Dragapult. Dragapult can just Shadow Ball it out. Shadow Ball is super effective against Sneasler (Ghost vs Fighting = super effective).
    
    Dragapult is faster and immune to Sneasler's STAB. Just Shadow Ball it out.
    
    The deciding factor: Dragapult is immune to Sneasler's Fighting/Poison STAB and faster, so Shadow Ball knocks it out safely.

    Chimps at the Zoo used Closecombat
    Ornith 1.5 35B used Shadowball1,923 tok · 9.8 s

    Dragapult is faster and Shadow Ball is super effective against Quaval's 4x Ghost weakness, likely KOing it. Even if it survives, Dragapult can U-turn out safely. No reason to switch into a potential Close Combat.

    Reasoning trace (123 words)
    Dragapult is faster and can 2HQ or OHQ Quaval with Shadow Ball. Quaval is Water/Fighting, 4x weak to Ghost. Shadow Ball is super effective and will likely KO. Dragapult has Curse Setters? No. Quaval has no revealed moves but is at 51%. Shadow Ball at 80 BP super effective against 4x weak target should KO. Let me estimate: Quaval HP ~176, Dragapult SpA 152, Choice Scarf doesn't boost SpA. Shadow Ball 80 BP, 4x weak = 4x damage. That's likely a KO. Even if not, Dragapult is fast and can U-turn out to Gholdengo or Garchomp. Actually Quaval could be Fighting type with Close Combat which 2HOs Dragapult, but Dragapult moves first. Shadow Ball should KO.
    
    Let me go with Shadow Ball.

    Dragapult is faster and Shadow Ball is super effective against the frail Sneasler, likely knocking it out before it can act. No need to switch since we have the matchup won.

    Reasoning trace (147 words)
    Sneasler is a physical attacker with possible unburden ability. If it holds an item, it's slow (126-189). Dragapult is faster at 213. Sneasler is Fighting/Poison, weak to Ghost. Dragapult's Shadow Ball is super effective and would knock it out. Sneasler's moves are physical Fighting/Poison, which Dragapult resists (Ghost resists Fighting, Steel/Ghost... wait Dragapult is Dragon/Ghost, Ghost resists Fighting). Actually Ghost type resists Fighting. So even if Sneasler survives, its physical moves do reduced damage.
    
    Shadow Ball is super effective against Sneasler and Dragapult is faster, so it should knock out Sneasler. Let me estimate: Sneasler def 72-123. Shadow Ball BP80 special, Dragapult SPA 152. That's likely to OHKO or at least 2HKO. Given Sneasler is frail and weak to Ghost, Shadow Ball is the play.
    
    Switching to gholdengo or garchomp isn't necessary since Dragapult is faster and has a super effective move. Just go Shadow Ball.

    Ornith 1.5 35B switched to Garchomp3,598 tok · 51.3 s

    Dragapult is nearly fainted (24 HP) and Shadow Ball won't knock out Sneasler at 54%, so Sneasler would kill it back (and could outspeed via Unburden). Garchomp's Earthquake OHKOs the Ground-weak Sneasler with no risk, so switch.

    Reasoning trace (873 words)
    Dragapult is at 24/163 HP and very fragile. Sneasler is at 54%. Sneasler has unburden ability, so if it loses its item (e.g., from a Choice item or fling or... actually Sneasler holds unknown_item). Sneasler's speed range is 126-189, which can exceed Dragapult's 213? No, 213 is Dragapult's max with scarf. Wait, Dragapult's base speed 142, at level 50 with scarf it's 213. Sneasler's possible range is 126-189, so Dragapult always moves first.
    
    Sneasler is at 54%. Dragapult's Shadow Ball (Ghost) vs Sneasler (Fighting/Poison): Ghost is immune to Fighting, and Sneasler is not Ghost-type, so Shadow Ball does normal damage. Sneasler is Fighting/Poison, weak to Ground, Psychic, Flying, and... Ghost? No. Sneasler resists Fighting, Poison, Bug, Dark, Grass. Weak to Ground (2x), Psychic (2x), Flying (2x). 
    
    Shadow Ball against Sneasler: Sneasler is Fighting/Poison. Ghost moves hit normally. So Shadow Ball does ~ damage. At 54% HP, will Shadow Ball knock out? Dragapult SPA 152, Shadow Ball BP 80, Sneasler SpD 90-145. Let's estimate: damage ~ (some formula). Roughly, Shadow Ball at +0 against a 54% HP target... it might not OHKO. Sneasler could survive and then hit back with Dire Claw (Poison physical) or a Fighting move. But Sneasler only has Dire Claw revealed. Dire Claw is Poison, not very effective against Dragapult (Ghost? No, Poison hits Dragapult normally, but "It was not very effective" was noted earlier against Dragapult—wait that was a crit and not very effective, meaning Dragapult resisted? Actually Poison vs Ghost is neutral. Hmm, the earlier note said "It was not very effective" for Dire Claw against Dragapult. That's odd. Maybe Sneasler had a different move. Anyway.)
    
    Actually, the key concern: Sneasler has unburden. If Sneasler holds an item and loses it, speed doubles. But we don't know its item. If Sneasler is at 54% and survives Shadow Ball, it could outspeed after unburden (if it lost item) and kill Dragapult. But Dragapult is already at 24 HP, basically one hit away.
    
    Better to switch to Gholdengo or Garchomp. Garchomp is Ground type—Sneasler is weak to Ground, and Garchomp's Earthquake would OHKO easily. Also Garchomp resists Sneasler's Fighting/Dire Claw? Garchomp is Dragon/Ground. Dire Claw is Poison—neutral. Earthquake is super effective.
    
    Actually, switching to Garchomp: Sneasler is weak to Ground, Garchomp Earthquake OHKOs. But Sneasler would get a free hit on Garchomp? No, switching is free, Sneasler doesn't move. Garchomp comes in and Earthquakes.
    
    But wait, is there a risk? Sneasler's Dire Claw could poison or paralyze Garchomp. But Garchomp OHKOs regardless.
    
    Alternatively, Dragapult could use Shadow Ball hoping to KO. But Sneasler at 54% might survive. Let me estimate Shadow Ball damage.
    
    Dragapult SPA 152 (base 150). Shadow Ball BP 80. Sneasler SpD 90-145 (base 90-145? The range given is 90-145). Actually Sneasler base SpD is 70, but with EVs/IVs it could be higher. Range 90-145.
    
    Damage formula (Gen 9): Damage = ((2*25/5 + 10) * BP * A/P / 100 + 2) * modifier
    = ((10 + 10) * 80 * 152 / SpD / 100 + 2) * modifier
    
    If SpD = 145: (20 * 80 * 152 / 145 / 100 + 2) = (20*80*152/14500 + 2) = (243200/14500 + 2) = (16.77 + 2) = 18.77. Times HP... wait that's the base. Then * modifiers (STAB? no, Ghost not STAB for Dragapult? Dragapult is Dragon/Ghost, Shadow Ball is Ghost, so STAB yes 1.5x). Critical? 1/24 chance.
    
    So with STAB: 18.77 * 1.5 = 28.15. Against a Pokémon with ~160 HP at 54% = ~88 HP remaining. 28 * something... hmm I need the actual HP. Let me reconsider.
    
    Actually the damage formula result is in HP points directly when using the target's Defense/SpD. Let me redo.
    
    Damage = (((2*25/5 + 10) * BP * (A/P)) / 100 + 2) * STAB * other * (random 85-100%)
    
    = ((10 + 10) * 80 * (152/SpD) / 100 + 2) * 1.5
    
    If SpD = 145: ((20 * 80 * 152/145)/100 + 2) * 1.5 = ((20*80*1.048)/100 + 2)*1.5 = ((1677/100)+2)*1.5 = (16.77+2)*1.5 = 18.77*1.5 = 28.15. Hmm that seems low. Wait, A/P where A=152, P=SpD. If SpD=145, A/P = 1.048.
    
    Actually let me reconsider. The target's current HP: Sneasler at 54%. If base HP ~160, current ~88. Shadow Ball does ~28 damage. That's only ~32% of its HP. So Shadow Ball does NOT KO. Sneasler survives.
    
    If SpD = 90: A/P = 152/90 = 1.689. Damage = (20*80*1.689/100 + 2)*1.5 = (2703/100+2)*1.5 = (27.03+2)*1.5 = 29.03*1.5 = 43.5. That's ~50% of 88. Still doesn't KO at 54%.
    
    So Shadow Ball won't KO Sneasler. Sneasler survives and can hit Dragapult (at 24 HP) with Dire Claw, killing it. Even if Dragapult survives (unlikely), Sneasler with unburden could outspeed.
    
    So switching is the right call. Switch to Garchomp for the Ground-type OHKO on Sneasler. Garchomp Earthquake 4x? No, Sneasler is 2x weak to Ground. Garchomp Earthquake BP 100, physical. Sneasler Def 72-123. Garchomp ATK 182. Earthquake will definitely KO Sneasler at 54%.
    
    But wait, does Sneasler have a Ground move? It only has Dire Claw revealed. So Garchomp is safe.
    
    Switch to Garchomp.
    
    Actually, let me double check: is there any risk with Garchomp coming in? Sneasler's Dire Claw could poison/Garchomp. But Garchomp OHKOs. Good.
    
    Switch: garchomp.

    Sneasler is at 42% and Garchomp's STAB Earthquake should KO it before it can act in most speed configurations. Sneasler's only moves are contact Fighting/Poison attacks, which trigger Rough Skin and can't hurt Garchomp much anyway. Earthquake is the cleanest finish.

    Reasoning trace (1,169 words)
    Sneasler is at 42% HP. Garchomp has Rough Skin, so Sneasler's contact moves (Poison Jab, Dire Claw) will take damage. Sneasler is poisoned? No, it's not poisoned. Let me think.
    
    Sneasler at 42%. Garchomp's Earthquake is super effective (100 BP Ground vs Fighting/Poison - Ground is neutral actually). Wait, Sneasler is Fighting/Poison. Ground moves: Ground is not very effective? No. Ground vs Fighting: neutral. Ground vs Poison: neutral. So Earthquake is neutral, not super effective. The prompt says "super effective on sneasler" - hmm, that's odd. Actually Ground doesn't affect... no. Let me reconsider. Ground vs Poison is neutral, Ground vs Fighting is neutral. So Earthquake is neutral. But the description says super effective. Maybe the tool is wrong, or maybe I'm misremembering. Actually, Ground-type moves do 1x against Poison and 1x against Fighting. So it's neutral.
    
    Wait, but the move description explicitly says "super effective on sneasler". That's strange. Let me just go with the game logic. Actually maybe the description is auto-generated and wrong. Regardless.
    
    Sneasler at 42%. Garchomp has Rough Skin. If Sneasler uses a contact move, it takes Rough Skin damage. But Sneasler could also use Dire Claw (non-contact) to poison/paralyze/confuse.
    
    The key question: can Garchomp knock out Sneasler? Sneasler at 42%. Earthquake 100 BP neutral... probably doesn't OHKO. Stone Edge is not very effective (Rock vs Fighting is neutral, vs Poison is neutral too - actually Rock vs Poison neutral, Rock vs Fighting neutral). Hmm, Stone Edge description says "not very effective on sneasler" - that's also weird.
    
    Actually wait. Let me reconsider type matchups. Sneasler is Fighting/Poison.
    - Ground vs Fighting: 1x. Ground vs Poison: 1x. So Earthquake = 1x (neutral).
    - Rock vs Fighting: 1x. Rock vs Poison: 1x. So Stone Edge = 1x (neutral).
    
    Both descriptions seem wrong. But regardless, the real question is whether to attack or switch.
    
    Garchomp at 83.6%. Sneasler at 42%. Sneasler is fast (126-189 speed range, could outspeed). If Sneasler hits first with Dire Claw or Poison Jab, and Garchomp has Rough Skin... 
    
    Actually, the bigger concern: Sneasler with Unburden could boost speed. But it hasn't dropped an item.
    
    Let me think about what's best. Garchomp is at 153/183. Sneasler at 42%. If I attack with Earthquake, I might not KO. Then Sneasler hits back. Poison Jab is contact, triggers Rough Skin. Dire Claw could poison Garchomp.
    
    Actually, the safest play might be to switch to Gholdengo, which is Ghost/Steel and immune to Fighting and Poison moves. Sneasler's only moves are Dire Claw and Poison Jab, both contact/Fighting/Poison. Gholdengo is immune to both. Gholdengo at 100% HP with Focus Sash.
    
    Wait, but Gholdengo can't knock out Sneasler easily. Gholdengo moves: Poltergeist (Ghost, 110 BP vs Fighting/Poison - Ghost is neutral vs Fighting, neutral vs Poison). Flash Cannon (Steel). 
    
    Hmm, but the point of switching to Gholdengo is to completely neutralize Sneasler. Gholdengo is immune to Fighting and Poison. Sneasler can only use contact moves (Poison Jab, Dire Claw) which are both Fighting/Poison type - Gholdengo is immune.
    
    But then I'd be stuck with Gholdengo vs whatever comes next. The opponent's bench has Goldengo (fainted), Quaquaval (fainted). All revealed fainted. So the opponent's team... they brought 3, all fainted? Wait, "The opponent brought 3 of the 6 it showed at team preview: all have been seen." And both Goldengo and Quaquaval are fainted. Sneasler is the active. So the opponent's remaining team is unknown - they could have any of the other 3.
    
    Actually, the opponent's revealed bench shows Goldengo [FAINTED] and Quaquaval [FAINTED]. So those two are gone. Sneasler is active. The opponent's 3rd member is unknown (could be anything from the original 6).
    
    So switching to Gholdengo to check Sneasler is good, but then Gholdengo faces an unknown. 
    
    Let me reconsider. Garchomp vs Sneasler: Garchomp is faster potentially but Sneasler could outspeed. If Garchomp attacks with Earthquake and doesn't KO, Sneasler hits. Poison Jab triggers Rough Skin (Sneasler takes damage). Dire Claw could status Garchomp.
    
    Actually, the deciding factor: Sneasler is fast and dangerous. Garchomp at 83% is risky. Switching to Gholdengo gives a free switch and immunity to Sneasler's moves. Gholdengo can then set up Nasty Plot or attack.
    
    But wait - is there a KO threat? Can Garchomp KO Sneasler? Sneasler at 42% with low defense (72-123). Garchomp Earthquake 100 BP... Let me estimate. Garchomp ATK 182, Earthquake 100 BP. Sneasler DEF ~100ish, HP ~170. Damage ≈ (2*50/5+2)*100*182/100/50 * modifiers. That's roughly (20+2)*100*182/5000 = 22*182/50 = 4004/50 = 80. Neutral, so ~80 damage. Sneasler at 42% of ~170 = ~71 HP. So Earthquake might KO! But it's described as super effective, which would make it more.
    
    Hmm, but the description says super effective which contradicts my type knowledge. Let me trust the type knowledge: Earthquake is neutral.
    
    Actually, I realize I should reconsider. Is Earthquake super effective? No. Ground doesn't get STAB bonus here (Garchomp is Dragon/Ground, so Earthquake gets STAB = 1.5x). So Earthquake damage with STAB: ~80 * 1.5 = 120. That would KO Sneasler at 42%!
    
    Wait, I forgot STAB. Garchomp's Earthquake gets STAB. So ~120 damage. Sneasler at 42% (~71 HP remaining). Yes, Earthquake STAB would KO.
    
    But Sneasler might outspeed and use Dire Claw first. If Dire Claw paralyzes Garchomp, Garchomp might not move. But Garchomp is faster usually (169 vs Sneasler's range). Sneasler's max speed 189 could outspeed.
    
    Hmm, this is a gamble. If Sneasler outspeeds and paralyzes, Garchomp might not KO.
    
    Alternatively, switch to Gholdengo which is immune. But then Garchomp's Earthquake KO is wasted.
    
    Let me think about the risk. Sneasler's Dire Claw: 30% poison, 30% paralyze, 30% confuse. If it paralyzes, Garchomp has 30% chance to not move. 
    
    Actually, the safer and strong play: Garchomp Earthquake likely KOs Sneasler with STAB. Even if Sneasler outspeeds, Poison Jab (contact) triggers Rough Skin damage but doesn't OHKO Garchomp (Garchomp at 83%). And Dire Claw paralyze is only 30%.
    
    But if I switch to Gholdengo, I completely avoid the risk and Gholdengo is immune. However, Gholdengo faces an unknown 3rd member.
    
    Given the KO potential, I think Earthquake is the aggressive correct play. But the risk of paralysis...
    
    Actually, let me reconsider the speed. Garchomp 169 speed. Sneasler 126-189. If Sneasler is at max speed (189), it outspeeds. But most Sneasler sets... Sneasler with Unburden and a Speed boost could be very fast. But without item loss, base speed 126-189 range.
    
    The deciding factor: Garchomp's Earthquake with STAB almost certainly KOs Sneasler at 42%. The only risk is paralysis from Dire Claw. Given Garchomp is usually faster and Rough Skin punishes contact moves, I'll go with Earthquake.
    
    Wait, but actually, let me reconsider whether Earthquake is even the best move. Stone Edge is described as "not very effective" which is wrong. Earthquake is super effective per the description (also wrong per my knowledge, but STAB makes it strong).
    
    Actually, I need to be careful. Let me re-examine: the tool says Earthquake is "super effective on sneasThinking budget reached. Stop thinking and give your final answer now.
