This clever loop turns Naru Meha, Master Wizard into a self-sustaining engine by utilizing her own entry trigger to continually copy Not Dead After All. Each time Naru Meha is sacrificed to Phyrexian Altar for mana, her persistent return effect brings her right back to the battlefield to restart the process. This endless cycle not only generates infinite colored mana and sacrifice triggers, but the accumulated Wicked Role tokens from Not Dead After All will simultaneously drain your opponents out of the game entirely.
