Dangerous Energy

This card can only be attached to a Darkness Pokemon. This card provides Darkness Energy only while this card is attached to a Darkness Pokemon. Whenever the Darkness Pokemon this card is attached to is your Active Pokemon and is damaged by an attack from your opponent's Pokemon EX (even if that Pokemon is Knocked Out), put 2 damage counters on the attacking Pokemon EX. (If this card is attached to anything other than a Darkness Pokemon, discard this card.)
