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.
Choose 1 of your opponent's Pokémon and do 50 damage to it. Don't apply weakness and resistance for Benched Pokémon
Flip 4 coins. This attack does 50 damage times the number of heads
