Unseen Forces · 096/115
Darkness Energy is a Energy card from the Unseen Forces expansion of the Pokémon Trading Card Game (card 096/115, Rare).
If the Pokémon Darkness Energy is attached to attack, 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.)
