If this Baby Pokémon is your Active Pokémon and your opponent tries to attack, your opponent flips a coin (before doing anything else required in order to use that attack). If tails, your opponent's turn ends without an attack.
Flip a coin. If heads, choose an Energy card attached to the Defending Pokémon. Your opponent moves that card to 1 of his or her other Pokémon. (If your opponent has no Benched Pokémon, this attack does nothing.)
