[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Dragonstrike]

Either that, or have a Pokemon that can guard a Pokemon that's buffing, but in the case of Psychic attacks that's pretty hard to do due to Iron interpretation of some Moves and thier interaction with Cover.

Unless you happen to have access to moves that are specifically designed to prevent damage, such as Light Screen/Reflect/Aurora Veil/Wide Guard.
