Impidimp

Prankster : This Pokémon's non-damaging moves have their priority increased by one stage.

Frisk : When this Pokémon enters battle, it reveals an opposing Pokémon's held item to all participating trainers. In a double battle, if one opponent has an item, this Pokémon will Frisk that Pokémon; if both have an item, it will Frisk one at random.

Pickpocket : Whenever a move makes contact with this Pokémon, if it does not have a held item, it steals the attacker's held item. This Pokémon cannot steal upon being knocked out. It can steal if the attacker has a Substitute, but cannot steal when its own Substitute is hit. If a move hits multiple times, only the last hit triggers this ability. If this Pokémon is wild, it cannot steal from a trained Pokémon.
