Rotom-Wash lead (Levitate, EQ immune, likely WoW). Swapping to Scarf Gholdengo (Good as Gold blocks WoW), then Make It Rain/Shadow Ball. Save Garchomp Mega for their Gholdengo/Kingambit (EQ). Kingambit late-game cleaner. Their Dragonite/Mimikyu threats: Stone Edge for Dragonite, Kingambit Iron Head for Mimikyu.
Reasoning trace (52 words)
```
Garchomp would get burned by Rotom's Will-O-Wisp since it's immune to Earthquake via Levitate, so I'm weighing switches like Kingambit, who'd also be burned. Gholdengo seems like the better answer since Good as Gold blocks status moves entirely, making Will-O-Wisp useless against it, while its Hydro Pump matchup is only neutral.

Claude Opus 5.5 used Shadowball3,902 tok · 695.9 s · $0.0138

Turn 2: Scarf Gholdengo (223 speed) Shadow Ball on Rotom-Wash (MIR is 1/4). Locked into Shadow Ball; switch out if their Kingambit (Dark resists, Sucker Punch) or Mimikyu comes in. Save Garchomp Mega EQ for their Gholdengo/Kingambit, Stone Edge for Dragonite. Kingambit is the late cleaner. Rotom has WoW, so keep Garchomp/Kingambit away from it.

Reasoning trace (78 words)

Calculating Gholdengo's scarf-boosted speed against Rotom-Wash, weighing how resisted Make It Rain would be versus neutral Shadow Ball, and considering whether Tricking the scarf onto Rotom could cripple it while costing Gholdengo its speed edge.

Shadow Ball math works out to roughly a 55% hit on Rotom, a solid 2HKO, and stays useful against most of their team aside from Kingambit's Dark resistance and Mimikyu's Disguise. Given Kingambit's sucker punch threat, I'll go with Shadow Ball here.

Claude Opus 5.5 used Shadowball5,809 tok · 394.0 s · $0.0274

Their Gholdengo is at 1% (prob Sash used), Garchomp ~8% after this Shadow Ball, Rotom-Wash full with WoW. If my Gholdengo falls, Kingambit (Overlord boost) Sucker Punches the weakened Garchomp and Gholdengo. Their Gholdengo may carry Focus Blast. Garchomp Mega handles Rotom with Dragon Claw/Stone Edge (EQ fails on Levitate); avoid WoW.

Reasoning trace (309 words)

Garchomp sits at 54% after the first Shadow Ball, and a second likely won't quite finish it off unless I get lucky with the roll or a SpD drop. I need to weigh the risk since Garchomp threatens back with Earthquake, which could seriously dent or even knock out Gholdengo despite its speed advantage from the Scarf.

My alternative is switching to my own Garchomp, though Mega Evolution isn't available right now, likely because the active Pokémon isn't the mega-capable one. Still, I'm leaning toward firing off Shadow Ball again since I move first and might just clinch the KO before their Earthquake becomes a problem — plus I want to preserve Gholdengo since it's valuable against their own nearly-dead Gholdengo and the lurking Rotom-Wash.

Running the math, Shadow Ball looks like it OHKOs their Gholdengo even without heavy investment, but the real question is the trade — if their Garchomp survives at around 8% after the exchange, Kingambit's Sucker Punch can finish it off, leaving their side down to just the 1% Gholdengo and Rotom against my remaining team.

Switching Garchomp in is risky since EQ still does heavy damage and a predicted Dragon Claw isn't guaranteed to OHKO given the speed tie uncertainty. Bringing in Kingambit instead eats a super-effective EQ but survives thanks to its bulk, which might be the safer play here.

Then Sucker Punch from Kingambit should finish off a weakened Garchomp, though I'm left with low HP. Shadow Ball could still work if my earlier roll wasn't max damage, and there's a chance the opponent switches out instead of pressing the attack, but I should plan around them clicking EQ since that's the most threatening line against me.

Switching Kingambit in predicting EQ would take too much damage, around 85%, so that's not a good option. I'll just go with Shadow Ball.

Turn 5
Muse Spark 1.3 switched to Rotom4,058 tok · 32.7 s · $0.0006
Plan: Preserve 7HP Scarf Chomp to return later with EQ to KO Gholdengo. Sac-ing now loses win-con. Switch Rotom to tank Shadow Ball, then Volt Switch or Hydro Pump to bring Chomp back safely for EQ KO. Keep 2HP Gholdengo hidden.

Claude Opus 5.5 used Shadowball3,956 tok · 393.8 s · $0.0086
My Scarf Gholdengo (223 speed) is locked into Shadow Ball and finishes their Garchomp now. Left after that: their Gholdengo at 1% (Sash likely used; my Shadow Ball kills it) and a full Rotom-Wash with Will-O-Wisp. Against Rotom, my Garchomp should Mega Evolve and use Dragon Claw or Stone Edge, since Earthquake fails on Levitate. Kingambit is the backup.

My scarfed Gholdengo outspeeds their 3% Garchomp at 223 speed, so Shadow Ball takes it out. Their Gholdengo is left at 1% with Rotom at full health, and mega evolution isn't available since it only works while Garchomp's active — so I'll just go with Shadow Ball now.

Claude Opus 5.5 used Shadowball4,377 tok · 513.6 s · $0.0143

Staying locked in Shadow Ball with Scarf Gholdengo (223 speed); each hit does about 44% to Rotom-Wash. Their Rotom-Wash (Will-O-Wisp) is at 56%, Gholdengo at 1% and Garchomp at 3%; Shadow Ball kills those two and I outspeed both. If my Gholdengo falls, use Kingambit's Sucker Punch to finish the low ones, and Garchomp Mega Dragon Claw/Stone Edge on Rotom (Earthquake fails on Levitate).

Reasoning trace (127 words)

Rotom's at 56% after that Shadow Ball, and another one should bring it down to roughly 12%, though it might Volt Switch or Hydro Pump out. Gholdengo's at 75% and could take a neutral Hydro Pump for around 35%, but sticking with Shadow Ball still seems right since the opponent's other two Pokémon are nearly dead at 1% and 3% and will fall to it too.

Garchomp's Earthquake would be super effective against Gholdengo, but since I outspeed with my Scarf at 223 speed, that shouldn't matter unless Garchomp also has a Scarf. Switching to Garchomp mega is an option but risks a burn from Will-O-Wisp, so staying in with Shadow Ball seems safer, and Kingambit is there as backup if Gholdengo doesn't survive the exchange.

Claude Opus 5.5 switched to Kingambit4,821 tok · 273.0 s · $0.0176
Their Garchomp (3%) outsped my Scarf Gholdengo, so it is likely Choice Scarf. It may OHKO my Garchomp with Dragon Claw, so lead Kingambit and Sucker Punch to KO it first. Rotom-Wash (35%, Will-O-Wisp, Hydro Pump, Sitrus used): Kowtow Cleave KOs it. Do not Sucker Punch into Will-O-Wisp. Garchomp is the backup.
Reasoning trace (95 words)
```
That opponent Garchomp outsped my scarfed Gholdengo at 223 speed, which suggests it's running a Choice Scarf too, possibly locked into a move now.

Weighing my options, Kingambit's Sucker Punch could pick off their weakened Garchomp if it attacks, but if it uses a status move the priority fails. The bigger worry is their Garchomp's Dragon Claw against my own low-HP Garchomp — the speed and type advantage means it could nearly OHKO before I get a turn, so switching Kingambit in now seems safer since it'll have priority once Sucker Punch is live.
```

Their Garchomp (3%, probably Scarf locked into Earthquake) faints to Sucker Punch. Rotom-Wash (35%, Will-O-Wisp, Hydro Pump, Sitrus used) faints to Kowtow Cleave; never Sucker Punch into Will-O-Wisp. If Rotom switches in on Sucker Punch, use Kowtow Cleave next. My Garchomp (Mega available later?) is the backup and can Dragon Claw Rotom.

```
Garchomp at 3% is likely scarfed and locked into Earthquake after using it turn 8 - if it attacks, Sucker Punch gets the kill first, but if it switches to Rotom instead, Sucker Punch whiffs. Using Kowtow Cleave instead risks Garchomp outspeeding and hitting Kingambit with a super-effective EQ first.

Rotom is down to 35% HP, so I'm checking if Kowtow Cleave with the boosted attack and item bonus does enough damage to knock it out — working through the math, it comes out to roughly 91 damage against Rotom's max HP of 157, well above the ~55 HP it has left, confirming the KO even accounting for potential burn.

Rotom's at 10%, and Kowtow Cleave did 25% last time even through the burn, so it should finish Rotom off. Sucker Punch is risky if they go for Will-O-Wisp or protect, but Kowtow Cleave never misses, so that's the safer choice.

Since Rotom protected twice already, the third Protect only has a 1/9 chance of going through, so Kowtow Cleave is the right call. Even if Rotom goes for Hydro Pump instead, Kingambit at 146 HP should tank it fine.
