Thermopod + Naru Meha, Master Wizard + Victimize

Thermopod

Naru Meha, Master Wizard

Victimize

How it works

1. Cast Victimize by paying its mana cost
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, targeting Victimize.
4. Holding priority, activate Thermopod by sacrificing Naru Meha.
5. Resolve the Naru Meha trigger, copying Victimize
6. Resolve the Victimize copy, sacrificing a creature and returning Naru Meha and another creature from your graveyard to the battlefield.
7. Repeat from step 3.

This loop thrives on an infinite recursive engine fueled by Victimize and Naru Meha, Master Wizard. You cast Victimize targeting two creatures in your graveyard, then interrupt it by flashing in Naru Meha, whose entry trigger copies the original sorcery on the stack. The copy resolves to return both Naru Meha and your sacrifice fodder back to the battlefield, while Thermopod provides the crucial sacrifice outlet that turns each iteration into a fresh supply of red mana. By continuously sacrificing Naru Meha to Thermopod before she can be permanently lost, you can endlessly repeat the process to generate infinite death triggers, enter-the-battlefield effects, and red mana.
