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.
