Once per turn: You can target 1 face-up Level 3 or lower monster you control; equip that target to this card. (You can only equip 1 monster at a time to this card with this effect.) While equipped with a monster by this effect, this card gains 800 ATK. If this card would be destroyed, you can destroy the monster equipped to it with this effect, instead.
