[ Pendulum Effect ] 
Once per turn: You can target 1 face-up Xyz Monster you control, and 1 Level 5 or higher monster you control; that Xyz Monster's Rank becomes equal to the Level of that Level 5 or higher monster, until the end of this turn (even if this card leaves the field). While you control more cards than your opponent does, this card's Pendulum Scale becomes 4.

[ Monster Effect ] 
Your opponent takes no battle damage from attacks involving this card. Once per turn: You can target 1 other face-up monster you control; this card's ATK becomes equal to that monster's current ATK, until the end of this turn.
