Card Text

Once per turn, you can either: Target 1 Machine-Type monster you control; equip this card to that target, OR: Unequip this card and Special Summon it in Attack Position. While equipped by this effect, if the equipped monster destroys an opponent's monster by battle: Draw 1 card. (A monster can only be equipped with 1 Union monster at a time. If the equipped monster would be destroyed, destroy this card instead.)
