Dragapult is asleep and cannot move, so I must switch. Gholdengo has a safe, strong matchup against Sylveon's revealed status/heal moves.

Azumarill isn't a legal action. I only have legal moves available. Let me reconsider. Annihilape is at 19% HP. It's Fighting/Ghost. My Goldengo is Steel/Ghost. Fighting moves are immune to Ghost, so Annihilape's Ice Punch is super effective against Goldengo. Goldengo is at 36% HP. The issue: Ghost moves don't work on Fighting types. So Poltergeist and Shadowball do nothing. Flashcannon is Steel, 0.5x on Annihilape (Fighting resists Steel? Actually Fighting resists Steel). Flashcannon won't KO. Nasty Plot boosts SpA by 2 stages. Then Flashcannon could KO. But Annihilape could survive one Flashcannon and KO Goldengo with Ice Punch. Wait, let me think about speed. Goldengo 104 vs Annihilape 99-156. Either could move first. If Annihilape moves first with Ice Punch, it's super effective. Goldengo at 36% — could it survive? Ice Punch BP 75 physical. Annihilape Atk 121-183. Goldengo Def 115. That's a lot of damage. At 36% HP (70 HP), Ice Punch might KO or nearly. Actually, the key problem: I can't switch (no legal switch). I must use one of the 4 moves. Poltergeist and Shadowball do nothing on Fighting type. Flashcannon is not very effective. Nasty Plot boosts. Best option: Nasty Plot to boost, then Flashcannon next turn. But will Goldengo survive Ice Punch? If Annihilape is faster, it hits. If slower, Goldengo Flashcannons first. Actually, Flashcannon at 0.5x on 19% Annihilape — will it KO? Let me estimate. Annihilape HP ~200, Def ~120. Goldengo SpA 137, Flashcannon BP 80. 0.5x effectiveness. Damage ≈ (some fraction). Probably doesn't KO at 19%. Hmm. But Nasty Plot gives +2 SpA (doubles). Then Flashcannon could KO. The deciding factor: I can't switch, and Ghost moves are useless. Nasty Plot is the only way to set up Flashcannon to potentially KO. But risk of being hit by Ice Punch. Actually wait — is there any way to KO Annihilape this turn? No Ghost works. Flashcannon won't KO at 19%. So I need Nasty Plot. Let me go with Nasty Plot to boost and win next turn with Flashcannon. Actually, let me reconsider whether Flashcannon can KO. Annihilape at 19%. If Flashcannon doesn't KO, Annihilape survives and I still need another turn. Nasty Plot + Flashcannon is the plan. But if Annihilape is faster and Ice Punch KOs Goldengo, I lose. Goldengo at 36% HP vs Ice Punch. Let me estimate: Ice Punch BP 75, Annihilape Atk ~150 avg, Goldengo Def 115. Damage ≈ 0.5 * (2*50/10+2) * 75 * 150/115 / 50 * 0.5 (super effective) * 0.85 (STAB no) ... roughly. This could be significant. Goldengo 70 HP. Might survive at low or might KO. Given the constraints, Nasty Plot is the best legal move to set up the win.
