Smoochum 54/64 - Neo Revelation Unlimited

Flip a coin. If heads, choose a Special Energy card attached to 1 of your opponent's Pokémon. Your opponent shuffles that card into his or her deck.

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