User exchanges held item with that of the target. Fails if the user or target is holding Mail, is Giratina-O, if either Pokemon has Sticky Hold, if the target has a Substitute, or if neither user nor target has a held item. Fails if the user or target is a Pokemon with Multitype holding a Plate item, or Genesect holding a Drive item.

So Mail, Girantina with a Griseous Orb, all the plates when Arceus is holding it, and Genesect with a Drive.
