Dark Hypno

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.

コインを1回投げオモテなら、自分以外の自分の「わるいポケモン」の持っているワザを1つ選び、そのワザのダメージや効果を、このワザのものとして使う。(選んだワザの効果などにしたがうことができないなら、このワザは失敗する。)

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

相手のベンチポケモンの数×20ダメージ。
