HS—Undaunted · 079/090
Darkness Energy is a Energy card from the HS—Undaunted expansion of the Pokémon Trading Card Game (card 079/090, 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.)
