   Plan: lead Dragapult (fastest, Focus Sash). Back: Gholdengo and Garchomp (Mega). Opponent has the same six as mine, so watch for Kingambit, Garchomp and Dragapult.

   Plan: Dragapult leads (Focus Sash). It outspeeds the opposing Garchomp, so use Draco Meteor now. Back: Gholdengo and Garchomp (Mega). Opponent has the same six as mine, so watch for Kingambit, Garchomp and Dragapult.

   Dragapult is at -2 SpA with Focus Sash intact. Kingambit has Supreme Overlord at 1 faint. Plan: U-turn to bring Garchomp in, then Mega Garchomp uses Earthquake, which is super effective on Kingambit. Gholdengo handles Corviknight, Incineroar and Dragapult, so keep it back. Watch for Sucker Punch and Kowtow Cleave.

   Reasoning trace (123 words)

   I'm noting Kingambit gets a 10% boost from Supreme Overlord with one ally fainted, likely running Kowtow Cleave, Sucker Punch, Iron Head, or Swords Dance. With Dragapult at -2 SpA, its Flamethrower damage against Kingambit would be super effective but significantly weakened, so I'm weighing whether that's still enough given Kingambit's bulk.
   
   Running the numbers, Flamethrower only chips around 28% of Kingambit's health, which is too weak to be reliable. I'm thinking Garchomp is a much better answer since its Earthquake is super effective on Kingambit's Steel typing and Garchomp outspeeds it, while Gholdengo's moves don't hit Kingambit hard. If Dragapult uses U-turn instead, Bug-type damage is resisted by Steel, but it lets Garchomp switch in safely without taking a hit first.

   Turn 2: Dragapult is at 1 HP and was forced out by its own U-turn. Switching to Garchomp, which should Mega and use Earthquake on Kingambit (78%, Life Orb, 1 faint on Supreme Overlord). Keep Gholdengo back, since Dark moves hit it super effectively. The opponent still has one more Pokémon to come from Gholdengo, Incineroar, Dragapult or Corviknight.

   Dragapult used U-turn, so I need to switch out. Kingambit is at 78% with Supreme Overlord down one faint already — I'm weighing Garchomp for the Earthquake coverage despite the Sucker Punch risk, and checking if Mega Evolution opens up after switching.
   
   Gholdengo is risky since Ghost takes double damage from Dark-type Sucker Punch while Steel is only neutral. Garchomp seems like the better call here, bringing Rough Skin chip damage against Kingambit's Life Orb recoil as I send it in.

   Claude Sonnet 5.5 used Earthquakemega4,431 tok · 4.9 s · $0.0101

   Turn 3: Garchomp Mega Evolves and uses Earthquake. It outspeeds Kingambit (78%, Life Orb, 1 faint on Supreme Overlord) and should KO it. Gholdengo is the safe back-up, but Dark moves hit it super effectively. Dragapult is at 1 HP with no Focus Sash left. The opponent's last Pokémon is one of Gholdengo, Incineroar, Dragapult or Corviknight.

   Checking Earthquake's damage against Kingambit at 78% HP, factoring Mega Garchomp's boosted attack stat and Kingambit's Supreme Overlord ability and Life Orb item to see if it secures the KO.

   Last opposing Pokémon is Incineroar (100%, Intimidate). Garchomp (Mega, Atk -1) outspeeds it, so use Earthquake, which is super effective. Incineroar may have Fake Out, Knock Off or Flare Blitz. Gholdengo is the backup. Dragapult is at 1 HP.

6. Turn 5

   Claude Sonnet 5.5 used Earthquake4,159 tok · 3.0 s · $0.0055

   Last opposing Pokémon is Incineroar (58%, Sitrus Berry used, Intimidate, Darkest Lariat). Garchomp (Mega, Atk -1, 133/185) outspeeds it. Earthquake did about 67% last turn, so a second one should KO. Gholdengo is the backup. Dragapult is at 1 HP.
