Flip a coin. If heads, the Defending Pokémon is now Asleep.
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 attack, such as discarding Energy cards. (No matter what type the Defending Pokémon is, Clefairy's type is still Colorless.)
In the Scarlet & Violet Series, this card was reprinted in Holofoil with its original Base Set artwork in the Pokémon Trading Card Game Classic. This reprint lacks a regulation mark and is thus not legal for tournament play.
