Holding priority, cast Naru Meha by paying its mana cost.
When Naru Meha enters, it triggers, copying Undying Malice, with the copy targeting Naru Meha.
Resolve the copy of Undying Malice.
Holding priority, activate Phyrexian Altar by sacrificing Naru Meha.
When Naru Meha dies, it triggers, returning it from your graveyard to the battlefield.
Repeat from step 3.
This clever loop turns Naru Meha, Master Wizard into a self-sustaining engine by utilizing Undying Malice to rescue her from the graveyard the moment she hits the chopping block. By sacrificing her to Phyrexian Altar right after copying the revival spell, you generate a steady stream of colored mana while continuously cycling her in and out of play. Because Undying Malice brings her back with a +1/+1 counter and Phyrexian Altar provides the sacrifice outlet, this perpetual motion machine yields infinite death triggers, sacrifice triggers, and mana to fuel the rest of your victory.
