This clever loop revolves around Naru Meha, Master Wizard and Electroduplicate, leveraging Naru Meha's entry trigger to perpetually copy the spell that brought her to the field. When Electroduplicate targets a creature, holding priority to flash in Naru Meha allows her to copy that very Electroduplicate, aiming the new copy right back at Naru Meha herself. The resulting token copy of Naru Meha enters the battlefield and immediately triggers her ability again to repeat the entire process, letting you bypass the legend rule by letting the original or the token head to the graveyard while keeping the endless chain of copies alive.
