Once during your turn (before your attack), if this Pokémon is in your hand, you may reveal it. If you do, heal 10 damage and remove a Special Condition from your Active Pokémon. Then, discard this Pokémon.
If the Defending Pokémon tries to attack during your opponent’s next turn, your opponent flips a coin. If tails, that attack does nothing.
