Armor Breaker

Once per turn, you can equip this card to a Warrior-Type monster you control, OR unequip it to Special Summon this card in face-up Attack Position. While equipped to a monster by this card's effect, each time the equipped monster inflicts Battle Damage to your opponent, destroy 1 card on the field. (1 monster can only be equipped with 1 Union Monster at a time. If the equipped monster is destroyed by battle, destroy this card instead.)
