Are there any items trick can't switch?

Question

Maybe Mega Stones, or Z-Crystals etc. I honestly don't know XD

Comments

It can't switch items held by a sticky hold Pokemon.

Answer 1

Trick can now exchange a Griseous Orb as long as neither the user nor the target is Giratina. Trick fails if the user or the target is Arceus when either Pokémon holds a Plate (Multitype has no effect on Trick), if the user or the target is Genesect when either Pokémon holds a Drive, if the user or the target is holding a Mega Stone or a colored orb that could allow either Pokémon to undergo Mega Evolution or Primal Reversion, if either Pokémon is holding Mail or a Z-Crystal, or if the user or the target is Silvally and either Pokémon is holding a memory.
