Darkness Energy (Reverse Holofoil) is a Special Energy card variant that provides Darkness Energy. When attached to an attacking Pokémon that is Darkness or has "Dark" in its name, it increases that attack's damage by 10 before applying Weakness and Resistance. It does not count as a basic Energy card, which matters for effects that reference basic Energy.
