Darkrai ◇ダークライ

AbilityNightmare Star

When you play this Pokémon from your hand onto your Bench during your turn, you may attach 2 Darkness Energy cards from your hand to it.

Your opponent's Active Pokémon is now Asleep. Your opponent flips 2 coins instead of 1 between turns. If either of them is tails, that Pokémon is still Asleep.
