Thermopod + Naru Meha, Master Wizard + Graceful Reprieve

Thermopod

Naru Meha, Master Wizard

Graceful Reprieve

How it works

1. Cast Graceful Reprieve by paying its mana cost.
2. Holding priority, cast Naru Meha by paying its mana cost.
3. When Naru Meha enters, it triggers, copying Graceful Reprieve, with the copy targeting Naru Meha.
4. Resolve the copy of Graceful Reprieve.
5. Holding priority, activate Thermopod by sacrificing Naru Meha.
6. When Naru Meha dies, Graceful Reprieve triggers, returning Naru Meha from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop spins up an endless engine by using Naru Meha, Master Wizard to continuously copy and redirect Graceful Reprieve back onto herself. When Naru Meha enters the battlefield, her triggered ability targets the Graceful Reprieve already resting safely on the stack, ensuring a fresh copy is always ready to resolve. From there, Thermopod steps in as the ultimate altar, allowing you to sacrifice Naru Meha for red mana whenever you please. Because Graceful Reprieve's delayed trigger catches her in the graveyard and brings her right back to the battlefield, you can repeat the whole cycle indefinitely to flood your pool with red mana and trigger every entrance and exit your heart desires.
