Ninja Boy (xy11-103) is a Supporter Trainer from the Steam Siege set. It lets you choose one of your Basic Pokémon in play and search your deck for a Basic Pokémon to switch into that spot, keeping attachments, damage, Special Conditions, and other effects on the new Pokémon while shuffling the original into your deck. This card is played under the normal Supporter timing and is limited by the rule that you may play only one Supporter during your turn.
