Smeargle

Search your deck for up to 3 basic Energy cards, show them to your opponent, and put them into your hand. Shuffle your deck afterward.

Cost: Colorless

Flip a coin. If heads, choose an attack on 1 of your opponent's Benched Pokémon. Trace copies that attack except for its Energy cost. (You must still do anything else required for that attack.) Smeargle performs that attack.
