  [ Monster Effect ]
  While you have 2 cards in your Pendulum Zones with the same Pendulum Scale, this card gains ATK and DEF equal to the Pendulum Scale x 100, and can attack your opponent directly. If this card inflicts battle damage to your opponent by a direct attack: Destroy all cards in the Pendulum Zones.
