Igglybuff

Pokémon Power: Gaze — Once during your turn (before your attack), choose 1 of your opponent's Benched Pokémon that has a Pokémon Power. That power stops working until the end of this turn. This effect ends if that Pokémon leaves the Bench. | 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.
