[PKM] Elekid (9/147) [Aquapolis]

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.)

If your Active Pokémon is a Baby Pokémon and your opponent announces an attack, your opponent flips a coin (before doing anything else). If tails, your opponent's turn ends.
