Darkness Energy (Special)   (#87,  Power Keepers)
Type:   Special Energy
Text:  If the Pokemon Darkness Energy is attached to attacks, the attack does 10 more damage to the Active Pokemon (before applying Weakness and Resistance). Ignore this effect unless the Attacking Pokemon is D or has Dark in its name. Darkness Energy provides D Energy. (Doesn't count as a basic Energy card.)
