Chained:
Each time an interrupt is played, if no card is stacked on this asset, you may pay 3 energy. If you do, stack that interrupt on this asset after its effects have been performed. As an additional cost for a player to play a card that has the same title as a card stacked on this asset, he or she pays 3 energy. "Those who cannot remember the past are condemned to repeat it." . George Santayana
