Power Keepers · 087/108
Darkness Energy is a Energy card from the Power Keepers expansion of the Pokémon Trading Card Game (card 087/108, Rare).
If the Pokémon Darkness Energy is attached to attacks, the attack does 10 more damage to the Active Pokémon (before applying Weakness and Resistance). Ignore this effect unless the Attacking Pokémon is Darkness or has Dark in its name. Darkness Energy provides Darkness Energy. (Doesn't count as a basic Energy card.)
