Metrognome (MP17-EN198) [2017 Mega-Tins Mega Pack]

<strong>Pendulum Effect :</strong> Once per turn: You can target 1 other card in a Pendulum Zone; this card's Pendulum Scale becomes equal to that card's, until the end of this turn.
<br><strong>Monster Effect :</strong> 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.
