[1] Sing
Flip a coin. If heads, the Defending Pokemon is now Asleep.
[3] Metronome
Choose 1 of the Defending Pokemon's attacks. Metronome copies that attack except for its Energy costs and anything else required in order to use that attack, such as discarding Energy cards. (No matter what type the Defending Pokemon is, Clefairy's type is still Colorless.)
