Dark HypnoわるいスリーパーUnlimited Holofoil

Flip a coin. If heads, choose an attack on 1 of your Pokémon in play that has Dark in its name (excluding this one). Dark Link copies that attack except for its Energy cost. (You must still do anything else required for that attack.) (No matter what type that Pokémon is, Dark Hypno's type is still Psychic Darkness.) Dark Hypno performs that attack.

Does 20 damage times the number of your opponent's Benched Pokémon.
