Darkness Energy (Special) - Reverse Holofoil Unseen Forces - 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.)
