This elegant loop transforms Not Dead After All into an endless cycle of resurrection by leveraging Naru Meha, Master Wizard's ability to copy spells upon entering the battlefield.

As you repeat this sacrificial dance, the cumulative triggers on the Wicked Role token attached to Naru Meha will relentlessly drain away your opponents' life totals while Viscera Seer lets you scry through your entire deck.
