Clefairy

Sing

Flip a coin. If heads, the Defending Pokémon is now Asleep.

Metronome

Choose 1 of the Defending Pokémon's attacks. Metronome copies that attack except for its Energy costs and anything else required in order to use that attach, such as discarding Energy cards. (No matter what type the Defending Pokémon is, Clefairy's type is still Colorless.)
