   Plan: lead Dragapult (fast, Focus Sash). Gholdengo and Garchomp (Mega) in back. The opponent has a mirror team, so watch for Kingambit and Gholdengo (Good as Gold blocks status).

   Lead Dragapult (Focus Sash). Gholdengo and Garchomp (Mega) in back. Opponent is a mirror team, so watch for Kingambit and Gholdengo (Good as Gold blocks status). Their Garchomp is the lead, speed 109-169, so Dragapult outspeeds it.

   Turn 2: Their Garchomp is down and Kingambit is in with Supreme Overlord (+10%). Dragapult is at -2 SpA, so U-turn out to Garchomp (Earthquake is super effective on Kingambit; Mega is available there). Gholdengo is weak to Dark moves, so keep it away from Kingambit. One more opposing mon is still to come: gholdengo, incineroar, dragapult or corviknight.

   Reasoning trace (124 words)

   I'm factoring in Kingambit's Supreme Overlord boost and Dragapult's lowered Special Attack from -2, calculating that Flamethrower deals 2x damage against the Dark/Steel typing but with reduced SpA the output drops significantly, around 76 effective SpA for the hit.
   
   Switching to options for next turn: Sucker Punch from Kingambit would hit Dragapult hard since Dark is super effective on Ghost, though the sash would block a one-shot. I'm also weighing Garchomp's Earthquake against Kingambit (super effective via Steel, neutral via Dark) as a strong follow-up, and considering Gholdengo's Make It Rain which gets resisted by Steel.
   
   I'll go with U-turn now since it does neutral damage and lets me safely pivot into Garchomp, who can absorb Kingambit's attack and mega evolve next turn.

   Turn 2: Dragapult is at 1 HP after U-turn, so it is out of the fight. Garchomp comes in against Kingambit (77%, Life Orb, Supreme Overlord +10%). Next turn: Mega Evolve Garchomp and Earthquake, since Mega Garchomp outspeeds Kingambit. Keep Gholdengo away from Kingambit's Dark moves. One more opposing mon is unseen: gholdengo, incineroar, dragapult or corviknight.

   Reasoning trace (56 words)

   With Dragapult down to 1 HP and forced out, I need to pick between Garchomp or Gholdengo against Kingambit, who's at 77% with Life Orb and one Supreme Overlord boost already. Garchomp's Earthquake hits Kingambit for super effective damage, which makes it the stronger switch-in option against Kingambit's likely Sucker Punch/Kowtow Cleave/Iron Head/Swords Dance set.

   Claude Sonnet 5.5 used Earthquakemega4,327 tok · 7.8 s · $0.0087

   Turn 3: Garchomp Mega Evolves and uses Earthquake on Kingambit (77%, Life Orb, Supreme Overlord). Dragapult is at 1 HP with no Sash left and is only good for a late revenge kill. Keep Gholdengo away from Kingambit's Dark moves. One opposing mon is still unseen: gholdengo, incineroar, dragapult or corviknight.

   Reasoning trace (82 words)

   Kingambit at 77% HP facing Mega Garchomp's Earthquake, which gets a 2x boost against Steel typing. With Mega Garchomp's boosted Attack, the Earthquake likely deals around 50-60%, so it might not be enough to knock out Kingambit outright.
   
   But Kingambit's Sucker Punch could hit first with priority if Garchomp goes for a non-attacking move, and Rough Skin punishes any contact moves Kingambit tries to use. There's also a chance Kingambit is running Swords Dance instead, which would change the calculation entirely.

5. Turn 4

   Claude Sonnet 5.5 used Earthquake4,352 tok · 6.4 s · $0.0124

   Opponent's last Pokémon is Incineroar, a Fire/Dark type with Intimidate. Mega Garchomp (-1 Atk) outspeeds it, and Earthquake is super effective on it. Dragapult is at 1 HP and only useful for a late revenge kill. Gholdengo is the backup.

   Reasoning trace (72 words)

   Incineroar is likely Fire/Dark, so Earthquake hits it hard despite Garchomp's -1 Atk and speed advantage. But I need to consider Incineroar could Fake Out on its first turn out, which would interrupt my attack.
   
   Since this seems to be a mirror match with unknown exact movesets, I'll just commit to Earthquake—it's super effective against Fire/Dark and should outdamage the alternative of Rockslide despite Flare Blitz recoil risk to my Garchomp.

   Opponent's last Pokémon is Incineroar at 53% HP (Sitrus Berry used). Mega Garchomp (-1 Atk) outspeeds it. Earthquake did about 47% last turn plus Sitrus healed it, so another Earthquake should KO. Dragapult is at 1 HP and Gholdengo is the backup.
