This looping sequence sets up an infinite engine of sacrifices and reanimations by perpetually targeting Naru Meha, Master Wizard with its own copied spell.

Goblin Bombardment provides the necessary outlet to instantly sacrifice her before she resolves the protection spell normally, turning each recursion cycle into repeatable damage and life loss.
