you probably want to add poison heal on there, or recovery. also someone can switch into a resist/immunity of choice and pp stall- Priority: This'll be able to hit you before you load up your move, be it by just a priority move, Prankster, Or Triage.
- Negative Priority: Moves like Dragon Tail, Roar, etc, also apply, being able to hit you once you come out of your invincible state.
- Slower Pokemon: This one is unlikely, but pokemon made for a trick room strat could beat you without a trick room, since they would be slower than you, making them able to hit you once your invulnerability ends.
-Toxic from poison types: Apparently this is one? IDK if it's true.
-Earthquake on Dig
I might've forgotten a few counters, but these are the main ones.
