#142: Darkness Energy (Special)

If the Pokémon Darkness Energy is attached to damages the Defending Pokémon (after applying Weakness and Resistance), the attack does 10 more damage to the Defending Pokémon. At the end of every turn, put 1 damage counter on the Pokémon Darkness Energy is attached to, unless it's or has Dark in its name. Darkness Energy provides Energy. (Doesn't count as a basic Energy card.)
