Dark Ampharosわるいデンリュウ

Pokémon PowerConductivity

Whenever your opponent attaches an Energy card from his or her hand to a Pokémon, this power does 10 damage to that Pokémon. (Don't apply Weakness and Resistance.) This power stops working if you have more than 1 Dark Ampharos in play or while Dark Ampharos is Asleep, Confused, or Paralyzed.

Discard all Lightning Energy cards attached to Dark Ampharos or this attack does nothing.
