As long as Misdreavus is your Active Pokémon, each player flips 2 coins for his or her Pokémon that is Asleep between turns. If either coin is tails, that Pokémon is still Asleep.

Return an Energy card attached to Misdreavus to your hand. The Defending Pokémon is now Asleep.

If the Defending Pokémon is not Asleep, this attack does nothing.
