>>34295254There's so many ways to cheese fights in Pokemon nowadays that I can't imagine legitimately getting stuck on one. As long as you have a modest amount of creativity it's trivially easy to beat everything in the game with how much you're given, as long as you don't mind changing your strategy around a little.
In addition to what others have suggested:
>Revive spamming on a Pyukumuku>spamming X SpDef until a Pokemon can tank its attacks>spamming Sand Attack with Lycanroc and hoping to get lucky with misses>literally anything with Focus Sash + Destiny Bond>parahax/confusion with Lanturn>probably a ton of other strategies I missed
