Max Move-specific mechanics
If the most recently used move was a Max Move, Copycat uses the base of that Max Move.
If the most recently used move was a Max Move and the user is not Dynamaxed, Encore locks the user into the base of that Max Move.

Exclusive fails in Max Raid Battles:
Knock Off (presumably the Berry-stealing moves too)
Perish Song (I think)
