   Muse Spark Open brought Garchomp,gholdengo,dragonite2,352 tok · 19.3 s · $0.0042

   Plan: Bring offensive setup core that covers opponent's threats. Garchomp pressures Kingambit/Scizor, Gholdengo beats Clefable/Rotom-Wash, Dragonite cleans Greninja with ESpeed and sets up. Keep momentum and avoid passive Tyranitar.

   Reasoning trace (172 words)

   Need bring 3. Opponent has Garchomp, Rotom-Wash, Scizor, Clefable, Kingambit, Greninja.
   
   We have Mega Garchomp, Mega Dragonite, Mega Tyranitar options but only one mega per battle? In this format Mega Evolution instead of Terastallization - can mega evolve one.
   
   Our team: Garchomp, Gholdengo, Dragonite, Kingambit, Tyranitar, Rotom-Wash.
   
   Opponent likely brings Greninja fast, Clefable unaware wall, Kingambit etc.
   
   We need coverage. Gholdengo good vs Clefable, Rotom-Wash. Garchomp strong. Dragonite multiscale good.
   
   Consider bringing Garchomp lead, Gholdengo, Dragonite for offensive pressure. Or need Rotom-Wash to handle Scizor? Actually Gholdengo resists Scizor? Scizor bug steel.
   
   Tyranitar stealth rock useful but maybe not needed in 3v3 singles?
   
   Best core: Garchomp + Gholdengo + Dragonite gives two megas but we can choose one. Alternatively Kingambit with Sash good vs Greninja.
   
   Opponent Greninja threatens Garchomp, Tyranitar. Dragonite resists water? Not really.
   
   Let's pick balanced: Garchomp lead, Gholdengo, Rotom-Wash provides defensive pivot. But then double ground weak to Greninja ice beam?
   
   Maybe bring Dragonite to handle Greninja with ExtremeSpeed.
   
   Plan: Bring Garchomp, Gholdengo, Dragonite. All offensive setup sweepers.

   Mirror Garchomp lead - speed tie at 169. Mega evolving drops Speed, so stay base form to keep tie. Dragon Claw is SE and best damage; Earthquake neutral. Keep Gholdengo/Dragonite for later coverage.

   Reasoning trace (175 words)

    to=self<|message|>We have Garchomp vs Garchomp lead. We have Mega. Opponent unknown item. Speed tie possible. We have 169 max speed. Opponent could be 169 too. Need to consider.
   
   We have Swords Dance, EQ, Dragon Claw, Protect.
   
   In mirror, Dragon Claw is SE. Earthquake neutral? Actually Garchomp Dragon/Ground, EQ not very effective? Ground vs Dragon neutral, vs Ground? Actually Ground vs Dragon neutral, but Garchomp is Ground so? Ground vs Ground? No. So Dragon Claw best.
   
   But we could Mega Evolve. Mega Garchomp stats: Atk higher, SpA higher, Spe drops to 92? Actually Mega Garchomp speed 92 base vs 102. So at level 50, Mega speed lower. So if we mega now we will be slower. So don't mega if we want speed tie.
   
   We have Rough Skin. Opponent may have Rough Skin or Sand Veil.
   
   Best play: Dragon Claw without mega to keep speed. Or Swords Dance? Risky.
   
   We should attack. Dragon Claw.
   
   Alternatively Protect to scout? But we want damage.
   
   We have notes: plan offensive setup core.
   
   So MOVE dragonclaw without mega.

   Muse Spark Open switched to Dragonite2,948 tok · 10.4 s · $0.0053

   Garchomp at 5 HP will faint to any attack, can't stay in vs Greninja. Need to switch. Dragonite with Multiscale can tank Ice Beam/Dark Pulse best and threatens ESpeed priority, while Gholdengo is weak to Dark. Preserve Gholdengo for later.

   Reasoning trace (293 words)

    to=self<|message|>Garchomp at 5 HP will die to any attack. Greninja likely faster? Our speed 169, Greninja up to 191. Could be faster. We need to switch. Garchomp is almost dead, but we can sacrifice? Better switch to Dragonite or Gholdengo. Greninja Water/Dark, likely Ice Beam, Dark Pulse, Hydro Pump. Dragonite resists? Dragonite takes neutral? Water neutral, Dark neutral. Gholdengo resists? Ghost/Steel resists? Let's think.
   
   We have Garchomp at 5 HP, will die to any hit, but we can switch. Need to preserve? Actually Garchomp is useless at 5 HP, will die to priority. Best switch to Dragonite who can ESpeed? Or Gholdengo?
   
   Greninja threatens Garchomp with Ice Beam. Switching to Dragonite: Dragonite weak to Ice. Gholdengo resists Ice? Steel resists Ice. Gholdengo good vs Greninja? Greninja Dark STAB super effective vs Gholdengo? Ghost weak to Dark. So Gholdengo takes SE Dark Pulse.
   
   Dragonite with Multiscale can tank one hit. Gholdengo with Life Orb can hit hard.
   
   Which is better? Greninja likely has Ice Beam for Garchomp/Dragonite. So Gholdengo might be safer? But Dark Pulse hits Gholdengo SE.
   
   We need to guess Greninja set. Protean Greninja often has Ice Beam, Gunk Shot, etc. Battle Bond is special.
   
   We have Dragonite with ESpeed priority to finish Greninja if low. But Greninja full HP.
   
   We should switch to Gholdengo? Let's see opponent's remaining unknown: could be Scizor, Kingambit, etc. Gholdengo beats Clefable.
   
   At 5 HP, Garchomp will die anyway, we should switch to Dragonite to threaten ESpeed and setup? Dragonite can tank with Multiscale.
   
   Probably best switch to Dragonite, as it can Roost and DD.
   
   Alternatively switch to Gholdengo to get Nasty Plot.
   
   We need to preserve momentum. Greninja is fast, likely will KO Garchomp if we stay. So we must switch.
   
   Choose SWITCH: dragonite.

   Greninja is now Ice-type after Protean Ice Beam. Dragonite at 12% will die to any attack but has +2 priority Extremespeed to strike first regardless of Speed. Mega evolving boosts power without losing priority, best chance to KO or chunk before fainting. Gholdengo resists Ice and can come in next if needed.

   Reasoning trace (138 words)

    to=self<|message|>Dragonite at 20 HP vs Greninja Ice type now. Greninja used Ice Beam, now Ice type. Dragonite has Extremespeed priority +2. Greninja likely faster but priority beats. Need to kill? Greninja HP 100%, Extremespeed 80 BP from 186 Atk vs Greninja def 87-141. Could do maybe 50%? But Dragonite low HP will die to any hit if not priority. Extremespeed is best. Mega evolve? Dragonite mega? Dragoninite mega gives? Probably boosts? But need priority kill. Mega evolving doesn't change priority. Could mega to increase power? Might be better. Let's mega extremespeed.
   
   Also consider switch to Gholdengo? Gholdengo resists Ice? Steel resists Ice. Could switch. But Dragonite can revenge with ESpeed. Greninja is Ice now, weak to? But ESpeed neutral.
   
   We should mega extremespeed to try to damage. If not kill, maybe next turn.
   
   Notes need plan.
   
   

   Muse Spark Open switched to Gholdengo2,470 tok · 6.4 s · $0.0030

   Greninja at 59% is Ice-type after Protean, Gholdengo resists Ice Beam and threatens KO with Make It Rain/Shadow Ball. Garchomp at 5 HP is dead weight, can't take any hit. Bring Gholdengo to tank and pressure.

   Reasoning trace (91 words)

    to=self<|message|>We have Garchomp at 5 HP, Gholdengo full. Opponent Greninja at 59% Ice type. We must switch. Garchomp 5 HP will die to any hit, but Gholdengo is better. Gholdengo resists Ice Beam (Steel resists Ice). Also Good as Gold blocks status. So switch to Gholdengo.
   
   We need notes: plan.
   
   We have to choose SWITCH: gholdengo.
   
   We should note opponent's Greninja protean Ice, Gholdengo resists, can threaten with Make It Rain / Shadow Ball. Garchomp useless at 5 HP. Preserve? Actually Garchomp will be sac.

   Muse Spark Open used Makeitrain2,976 tok · 22.4 s · $0.0054

   Plan: Greninja at 59% Ice-type is weak to Make It Rain (SE + STAB + LO should KO). Gholdengo resists Ice Beam, so can tank one hit. Don't setup, just attack. Preserve 5 HP Garchomp as sack. Watch for Dark Pulse becoming SE vs Ghost.

   Reasoning trace (318 words)

   We have Gholdengo vs Greninja Ice type 59%. Make It Rain is super effective on Ice. With Life Orb and 203 SpA, should KO? Let's see: Greninja HP ~147-179, 59% means ~86-105 HP left. Make It Rain 120 BP *1.5 SE =180, plus STAB? Gholdengo Steel type yes STAB 1.5 =>270 effective. Life Orb 1.3 =>351. Should KO even with modest SpD. Shadow Ball also neutral? Ghost vs Ice neutral. Make It Rain best.
   
   But need consider Protean: Greninja will change type based on move it uses. If it uses Dark Pulse next, becomes Dark, then Make It Rain not SE (Steel vs Dark neutral). But still strong. However if it stays Ice, we KO.
   
   Should we Nasty Plot? No, we can just attack. Greninja faster, will attack first. What does Greninja do to Gholdengo? Ice Beam vs Gholdengo: Steel resists Ice (0.5x). So Ice Beam not very effective. Gholdengo has 111 SpD, should tank. Could Greninja have Dark Pulse? Likely. Dark vs Steel/Ghost? Dark vs Steel neutral? Actually Dark vs Steel? Not very effective? Wait Dark vs Steel = not very effective? No, Dark vs Steel is not very effective? Let's recall: Dark is not very effective vs Fighting, Dark, Fairy. Steel resists? No. So neutral. Ghost resists? Ghost vs Dark? Ghost is weak to Dark? Actually Ghost is weak to Ghost and Dark. So Gholdengo Ghost takes super effective from Dark. So Dark Pulse would be super effective (Ghost weak). Could be dangerous.
   
   But Greninja just used Ice Beam twice, now Ice type. If it uses Ice Beam again, resisted. If it switches to Dark Pulse, becomes Dark type, then Make It Rain neutral but still high power.
   
   We should just attack. Make It Rain is best to secure KO before it can do more.
   
   Also consider opponent's third mon unknown. Need preserve.
   
   So decision: Make It Rain.
   
   Notes need to keep within 60 words.

   Muse Spark Open used Makeitrain3,152 tok · 3.2 s · $0.0052

   Greninja at 59% is Ice-type, Make It Rain is 4x effective (Steel SE vs Ice + STAB) and should KO with Life Orb + 203 SpA. Gholdengo resists Ice Beam but weak to Dark Pulse; last turn Dark Pulse did ~94 dmg and flinched. Must attack now to remove Greninja before it flinches again, even with LO recoil.

   Reasoning trace (376 words)

   We have Gholdengo 100/194 vs Greninja 59% Ice type. Make It Rain is super effective on Ice. Should KO. But Greninja faster, will attack. Gholdengo at 51% might survive? Greninja Ice Beam vs Gholdengo: Gholdengo resists Ice (Steel). So Ice Beam not very effective. Dark Pulse super effective vs Ghost. Last turn Greninja used Dark Pulse and flinched. So it is now Dark type? Protean once per switch-in. Wait description: Once per switch-in. So after first Ice Beam it became Ice. Then Dark Pulse second time? But protean once per switch-in means second move doesn't change type? Actually in gen9 protean once per switch-in. So after Ice Beam it is Ice, Dark Pulse stays Ice type? But log says Dark Pulse was super effective vs Gholdengo. If it were Ice-type Dark Pulse, it would be neutral (Dark vs Steel/Ghost = super effective vs Ghost, neutral vs Steel => super effective). So still super effective. So type remains Ice.
   
   So Greninja is Ice type, Dark Pulse is Ice-type move? No, move type stays Dark, but user's type is Ice. So Dark Pulse still Dark type attack.
   
   Gholdengo resists Ice Beam, weak to Dark Pulse. Greninja used Dark Pulse last turn. Will it use Dark Pulse again? Likely. Gholdengo at 100 HP, Dark Pulse damage? Greninja SpA 137-203, Gholdengo SpD 111. Dark Pulse BP80. Super effective. Could do ~? Let's estimate. Might be ~60-80 damage. Gholdengo could survive one.
   
   We have option Recover to heal, or Make It Rain to KO. Greninja at 59% HP. Make It Rain 120 BP *1.5 STAB *2 SE = 360 effective, plus Life Orb 1.3, SpA 203. Should KO Greninja even with low roll. So attack.
   
   But if we attack we take Life Orb recoil 19 HP, plus Greninja attack. If Greninja Dark Pulses, we might die? 100 HP - Dark Pulse damage (~70) - LO recoil 19 = 11 HP left maybe survive. If we Recover, we heal to ~197 but take Dark Pulse.
   
   Which is better? Need to KO Greninja now. If we Recover, Greninja stays alive and can attack again. Better to Make It Rain and try to KO. Even if we faint next turn to third mon, we have Garchomp 5 HP useless.
   
   So Make It Rain.

   Greninja locked Ice-type (Protean once per switch-in) at 59%. Garchomp 5 HP must KO now or lose; no other mons left. Earthquake 100 BP > Dragon Claw 80 BP, both neutral vs Ice, best chance to KO before Greninja attacks. Speed tie uncertain but must attack.

   Reasoning trace (396 words)

   We have Garchomp at 5 HP vs Greninja 59% Ice type. Garchomp has 169 speed, Greninja 145-213. Could be faster. We have 5 HP, any hit kills us. We have protect, earthquake, dragonclaw, swords dance.
   
   Greninja is Ice type currently. Earthquake? Ground vs Ice neutral. Dragon Claw vs Ice? Dragon neutral vs Ice. Which does more? Earthquake 100 BP vs Dragon Claw 80 BP. But Greninja is Ice type, but originally Water/Dark. Protean changes type to move used. Last move Dark Pulse, so now it's Dark type? Wait log: Turn 4 Greninja used Dark Pulse, Turn 5 used Dark Pulse. So after Turn 5, its type is Dark. The display says (Ice) but that might be outdated? Actually it says (Ice) active. But it used Dark Pulse last two turns, so should be Dark. Maybe display bug? Let's see: Turn 2 Ice Beam -> Ice type. Turn 3 Ice Beam -> still Ice. Turn 4 Dark Pulse -> should become Dark. Turn 5 Dark Pulse -> Dark. But UI says Ice. Could be that Protean once per switch-in, so after first Ice Beam, it stays Ice, cannot change again. Indeed Protean: Once per switch-in. So it stays Ice! Good.
   
   So Greninja is Ice type. Earthquake neutral, Dragon Claw neutral. Earthquake 100 BP better. But Greninja is Water/Dark originally but now Ice, so Ground hits neutral.
   
   We are at 5 HP, we will die to any attack. Protect could scout? But we have no other Pokemon. Gholdengo fainted, Dragonite fainted. Only Garchomp left at 5 HP. So we must attack and hope we outspeed and KO. Greninja at 59% HP. Can Earthquake KO? Let's estimate. Garchomp Atk 182, Greninja Def 87-141. Earthquake 100 BP. 59% HP ~ maybe 88-105 HP remaining. Damage calc: Atk 182 vs Def ~ 100, 100 BP, level 50. Approx damage ~ (22*182*100/100/50)+2 ~ ~80-95. Might KO if low defense. Dragon Claw 80 BP less.
   
   We have Garchompite item, but Mega available No (maybe already used? Actually we didn't mega Garchomp, we mega Dragonite. So mega should be available? But says No. Maybe because Garchompite requires mega evolution but we already mega evolved Dragonite, only one mega per battle. So no.
   
   We need to choose best move to KO. Earthquake is strongest.
   
   Protect does nothing, we lose anyway.
   
   So MOVE earthquake.
   
   Also consider Swords Dance would boost but we die.
   
   So attack.
