Gengar LV.X

Compound Pain This attack does 30 damage to each of your opponent's Pokémon that already has any damage counters on it. (Don't apply Weakness and Resistance for Benched Pokémon.) Level-Down Once during your turn (before your attack), you may choose 1 of your opponent's Pokémon LV.X. Remove the Level-Up card from that Pokémon and have your opponent shuffle that card into his or her deck. The power can't be used if Gengar is affected by a Special Condition.
