When this card is Normal Summoned: You can target 1 Union Monster in your Graveyard; Special Summon it. 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. While equipped by this effect, the equipped monster cannot be targeted by your opponent's card effects. (If the equipped monster would be destroyed by battle or card effect, destroy this card instead.)
