Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn, you can equip this card to a "Soitsu" you control, OR unequip it to Special Summon this card in face-up Attack Position. When equipped to a monster by this card's effect, that monster gains 2500 ATK. (A monster can only be equipped with 1 Union Monster at a time. If the equipped monster would be destroyed by battle, destroy this card instead.)
