3 Level 4 monsters Once per turn: You can detach 1 material from this card to target 1 face-up Attack Position Effect Monster your opponent controls; equip that target to this card. At the start of the Damage Step, if this card battles a monster: Destroy that monster. This monster must be equipped with a monster with the same attribute as the monster it is battling to activate and to resolve this effect. * The above text is unofficial and describes the card's functionality in the OCG.
