The Pokémon steals the held item of a Pokémon it hits with a move.
Effect
Whenever this Pokémon hits another Pokémon with a move (other than Future Sight or Doom Desire), if it does not have a held item when the attack is selected, it steals the target's held item. This ability cannot steal a Griseous Orb from Giratina, a Gilded Crown or Wilted Crown from Athlauria, a Plate from a Pokémon with Multitype, a Drive from Genesect, or a Mega Stone from its corresponding Pokémon. If this Pokémon is wild, it cannot steal from a trained Pokémon.
