Can you trick plates onto arceus and the griserious orb onto giratina?

Question

Use the move trick becuase that could ruin these pokemon

Answer 1

"The user switches held items with the target. It fails if neither has a held item, if either Pokémon is holding Griseous Orb or Mail, if the target has a Substitute, or if either Pokémon has Sticky Hold. It also fails if either Pokémon has Multitype and either is holding a plate."

Straight from Bulbapedia, so anything with a plate or Multitype fails. Since Arceus is both, then it will obviously fail. However, in Generation V, you CAN use trick on a Griseous orb, but only as long as the target nor the user is Giratina, so it's essentially useless.

Answer 2

No, you can't unless you use an action replay.
