When this card is Normal or Special Summoned from the hand: You can destroy as many monsters on the field as possible (other than this card), and if you do, inflict damage to your opponent equal to the original ATK of the 1 destroyed monster with the highest original ATK (your choice, if tied), and if you do that, this card's ATK becomes equal to the damage they took. Once per turn, during your End Phase: Halve your LP.
