Clefable ex

Choose 1 of the Defending Pokémon's attacks. Metronome copies that attack except for its Energy cost. (You must still do anything else in order to use that attack.) (No matter what type that Pokémon is, Clefable ex's type is still Colorless.) Clefable ex performs that attack.

When Pokémon-ex has been Knocked Out, your opponent takes 2 Prize cards.
