    Plan: Bring an offensive core of scarf gholdengo, mega garchomp, and lifeorb dragapult. Gholdengo lead pressures Clefable/Kingambit and can trick a wall; Mega Garchomp sets rocks and breaks Rotom-W/Clefable with Scale Shot/SD; Dragapult cleans with speed and U-turns for momentum. Watch Greninja (Protean) and Scizor bullet punch — keep Dragapult healthy for late game.

    Reasoning trace (59 words)
    Strong core: gholdengo scarf, mega garchomp, dragapult. Consider slowkinggalar for special bulk vs greninja/rotom. But gholdengo handles kingambit and clefable well. Lead garchomp for rocks? Let's bring gholdengo, garchomp, dragapult — standard offense. Actually dragapult can U-turn scout. Lead dragapult? Gholdengo scarf leads well vs clefable/kingambit. I'll lead gholdengo, then garchomp, dragapult.

Hmm, opponent's Greninja threatens gholdengo. Still fine.

    Turn 1: Scarf Gholdengo outspeeds Greninja (223 vs max 191). Focus Blast is super effective and likely OHKOs Greninja, but only 70% accurate. If I miss, Gholdengo takes a hit (Water/Dark move). Switching to Garchomp risks a Water move. Plan: hit Focus Blast; if it survives, Gholdengo can finish later with Shadow Ball/Make It Rain.

    Reasoning trace (101 words)
    Gholdengo has scarf. Greninja Water/Dark. Focus Blast is super effective and Gholdengo likely outspeeds with scarf (149*1.5 = 223.5, definitely faster than Greninja max 191). Focus Blast 70% accuracy though. Alternatively trick to cripple. Shadow Ball is not very effective.

Actually, if Greninja is Protean and uses a Dark move, Gholdengo... Focus Blast kills Greninja if it hits. Risk: 70% accuracy. Shadow Ball does modest damage. If Greninja uses water shurken or dark pulse...

I'll go focusblast — high reward. But30% miss chance. Hmm. Alternatively switch to garchomp which resists... Greninja water move would hurt garchomp badly too.

Let's use focusblast.

    Turn 1: Scarf Gholdengo OHKO'd Mega Greninja with Focus Blast. Now facing Rotom-Wash; I'm locked into Focus Blast by Choice Scarf. Good as Gold blocks Will-O-Wisp, and Rotom's STABs are only neutral, so Gholdengo is safe to stay in. Fire Focus Blast for chip — 30% chance to miss, but switching risks a Hydro Pump on Garchomp. Opponent's last mon is likely Scizor/Kingambit/Clefable/Garchomp.

    Reasoning trace (117 words)
    Gholdengo is scarfed, locked into Focus Blast. Rotom-Wash resists... no, Fighting hits Rotom-Wash neutrally? Rotom-Wash is Electric/Water — Fighting is neutral. Focus Blast 120 BP neutral, but I'm locked in. Actually only option is focusblast or switch. Focus Blast is 70% accuracy, neutral, decent damage. Rotom-Wash is specially bulky. Could switch to Garchomp — but Rotom likely uses Hydro Pump/Volt Switch. Garchomp takes Water move badly. Dragapult could come in on a Volt Switch.

Locked into Focus Blast — probably just fire it. If it hits, decent chip. Rotom can't do much to Gholdengo except Volt Switch (neutral) or Hydro Pump (neutral). Good as Gold blocks status (Will-O-Wisp). So Gholdengo is fine vs Rotom. Fire Focus Blast.

    Scarfed Gholdengo locked into Focus Blast; Rotom at 62% with Leftovers. Gholdengo likely outspeeds but Focus Blast won't KO, and Hydro Pump KOs Gholdengo next. Switch to Dragapult — Water is resisted by Dragon, preserving Gholdengo for later. Dragapult outspeeds everything and can U-turn for momentum or Dragon Darts. Opponent's last mon is likely Kingambit/Scizor/Clefable/Garchomp.

    Reasoning trace (396 words)
    Gholdengo at 74 HP, locked into Focus Blast. Rotom at 62%. Focus Blast did 56% last time (from 100 to 56... wait, actually Rotom is at 56% then healed to 62% with leftovers). So Focus Blast does ~44-56%. Another Focus Blast could KO if it hits high roll, but Rotom likely KO's Gholdengo with Hydro Pump (74 HP, Hydro Pump does ~50%+).

Actually Gholdengo at 74/162 = 45.7%. Hydro Pump did 88 HP last turn (162-74=88... wait, it went from 162 to 74, so 88 damage = 54%). So Hydro Pump does ~54%, Gholdengo survives at ~20 HP if it goes first.

Scarfed Gholdengo at 149*1.5 = 223 speed vs Rotom 95-151. Scarf should outspeed unless Rotom is very fast. Actually 149*1.5 = 223.5, so definitely outspeeds Rotom max 151.

So Focus Blast goes first. If it hits (70%), Rotom goes from 62% to ~18-6%. Not a KO. Then Rotom Hydro Pump KOs Gholdengo probably (54% damage vs 45.7% HP).

Alternatively switch to Garchomp. Garchomp takes Hydro Pump (~neutral? Water vs Dragon/Ground = neutral, 2x effective on... no, Water is neutral on Dragon, 2x on Ground = 2x effective). Actually Water vs Dragon/Ground: Dragon resists Water, Ground weak to Water = neutral. So Hydro Pump does neutral damage.

Switching to Garchomp lets me set up or EQ. But Rotom has Levitate so EQ won't work. Scale Shot would work.

Hmm. Gholdengo locked into Focus Blast isn't great. Switching to Garchomp to take a Hydro Pump (neutral) and then Scale Shot Rotom seems good. Or switch to Dragapult which resists Water (Dragon resists Water) - takes ~27% and can U-turn or Dragon Darts.

Actually Dragapult is a great switch: Water resisted, outspeeds everything, can Dragon Darts. But then Rotom might switch to Clefable/Kingambit.

I think switching to Garchomp is solid - it's the wallbreaker. Or Dragapult for momentum with U-turn.

Let me think about what's optimal. Gholdengo at 45% locked into Focus Blast - it's still useful for late game if I can unlock it (can't, scarf). Actually it's permanently locked until switch. 

Switching to Dragapult: takes resisted Hydro Pump (~27%), then I can U-turn out or attack. This preserves Gholdengo for later (though locked into FB when it comes back).

Switching to Garchomp: takes neutral Hydro Pump (~54%?), then can Scale Shot or set up SD.

I'll switch to Dragapult for the resist and speed advantage.

    Dragapult outspeeds Rotom (194 vs ≤151). Dragon Darts with Life Orb + STAB should KO Rotom at 68% — roughly 50-60 per hit, two hits. U-turn only does ~55 total and gives up my speed advantage. Kill Rotom now; their last mon is likely Kingambit/Scizor/Clefable/Garchomp. Dragapult's Fire Blast threatens Scizor/Clefable later; keep Garchomp healthy for Kingambit.

    Dragapult vs Rotom-Wash. Dragon Darts does good damage. U-turn gives momentum and chip. Rotom at 68%. Dragon Darts: 189 Atk, Life Orb 1.3x, STAB 1.5x, BP 50x2. Rotom defense ~144. Roughly 25% per hit? Let's estimate: 189*1.5*1.3*50/ (144*2... ) Actually damage formula: ((2*50/5+2)*189*50/144)/50... let me compute: base = (2*50/5+2)*A*D... standard: damage = ((2*Level/5+2)*BP*A/D)/50 + 2, times modifiers. Level 50: 2*50/5+2 = 22. 22*50*189/144 = 22*50=1100, *189=207900, /144=1443.75, /50=28.875+2=30.9. Times STAB 1.5 = 46.3, times Life Orb 1.3 = 60.2 per hit. Two hits = 120. Rotom HP ~141. So ~85% of HP. Not quite KO but close. Rotom at 68% = ~96 HP. Two hits of 60 = 120 > 96. So Dragon Darts KOs Rotom if both hit and defense is mid-range. If Rotom max def 174: 22*50*189/174=1191, /50=23.8+2=25.8*1.5*1.3=50.3 per hit, 100 total. Still likely KO at 68% (96 HP). Hmm, 100 vs 96, close. Min def 114: definitely KO.

U-turn: 70 BP, 189 atk, Life Orb, STAB? Bug not STAB for Dragapult. 22*70*189/144 = 22*70=1540*189=291060/144=2021/50=40.4+2=42.4*1.3=55. Not a KO, and U-turn switches me out — I'd lose momentum but gain switch advantage. Dragon Darts seems better: likely KO.

Risk: Rotom could outspeed? No, Dragapult 194 vs max 151. Rotom could have Thunderbolt but doesn't matter.

Dragon Darts to KO Rotom.

    Rotom at 68% with Leftovers; Dragapult outspeeds. Dragon Darts (Life Orb + STAB) should deal ~58 per hit, two hits ≈ 116 damage vs Rotom's remaining ~85-107 HP — likely KO. Fire Blast risks a miss and is resisted. U-turn wastes damage if it KOs anyway. Kill Rotom now; last mon is Scizor/Kingambit/Clefable — Fire Blast threatens Scizor/Clefable, Garchomp handles Kingambit.

    Rotom at 68%. Dragon Darts should KO. Two hits of ~50 each with Life Orb STAB. Rotom defense 114-174. Let's estimate: Dragapult Atk 189, Life Orb 1.3, STAB 1.5 → 189*1.5*1.3 = 368.5 power factor... damage per hit = (368.5/50... let's do: BP 50 * 1.5 STAB * 1.3 LO = 97.5 effective BP. Against Def ~144: 22 + 97.5*144/50 = 22 + 280 = 302 / 256... damage formula: (2*50/5+2)*BP*Atk/Def/50+2 → (22)*97.5*189/144/50+2 = 22*97.5=2145; *189=405,405; /144=2815; /50=56.3; +2 = 58. Two hits = 116. Rotom HP 125-157, 68% → 85-107. So KO likely. Dragon Darts it.
