A Class - Watchtower

Once per turn, during your opponent's Main Phase or Battle Phase, you can: Immediately after this effect resolves, Xyz Summon 1 Xyz Monster, using only this card you control and "A Class" cards that are equipped to this card (this is a Quick Effect). Once per turn, you can either: Target 1 "A Class" monster you control; equip this card to that target, OR: Unequip this card and Special Summon it in face-up Attack Position. If the equipped monster attacks a Defense Position monster your opponent controls, before damage calculation: You can destroy that monster. If the equipped monster destroys an opponent's monster by battle and sends it to the Graveyard: You can add 1 "A Class" monster from your Deck to your hand, except "A Class - Watchtower". If the equipped monster would be destroyed, destroy this card instead. You can only gain this effect once per turn.
