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.
Vision
Once during your turn (before you attack), you may look at the top two cards of your deck, choose 1 and put it in your hand. Put the other card at the bottom of your deck.
