NPC trainers ideas thread

[DizzyEgg]

Hello.
One of the things that's really annoying for me as a player is how easy, repeating and not-interesting npc trainers are. I'd like this thread to grow into a source of interesting strategies or gimmicks for npc trainers in all stages of the game. Obviously I don't mean anything leader-level, but something that could surprise the player had they been incautious. Here are some of my ideas.

Spoiler:

General:
3 Gravelers. Two of which don't have Sturdy, the last having that ability along with selfdestruct.
One Pokemon that uses endeavour, faints and the switched in one knows Pursuit.
Double Battle, using Swagger against a pokemon with Own Tempo.
Mimic + Imprision combo (would be hard to pull up).
Early game:
Generic pokemon with leer/howl/growl/sand attack to lower that stats, second one attacks(Zigzagoon with Headbutt at lvl 9 comes to mind).
Bide on a Pokemon holding Oran Berry.
Mid game:
Curse on a Pokemon holding white herb.
Double battle, one pokemon uses follow me, the other sets up.
Double battle, earthquake if the partner is a flying type.
Encore + Taunt/Torment

ngl I got really excited when I saw this thread because I thought it was going to be ideas for non-Trainer NPCs because I definitely struggle with them a lot more.

As for Trainers, I think themed teams that pertain to their pre-battle dialogue is always fun. Trainers that only use monkey Pokémon or something, for example.
