YuGiOh! - Voidweaver Arcthelon

If this card is Normal or Special Summoned: You can place 1 “Void Counter” on all face-up monsters your opponent controls. Monsters with a “Void Counter” lose 300 ATK/DEF and cannot activate their effects during your opponent's next turn. Once per turn (Quick Effect): You can remove 2 “Void Counters” from the field; banish 1 card on the field or in either GY. If this card would be destroyed by battle or card effect, you can remove 1 “Void Counter” from anywhere on the field instead.
