Secret Wonders · 129/132
Darkness Energy is a Energy card from the Secret Wonders expansion of the Pokémon Trading Card Game (card 129/132, Uncommon).
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 if the Pokémon that Darkness Energy is attached to isn't Darkness. Darkness Energy provides Darkness Energy. (Doesn't count as a basic Energy card.)
