Thermopod + Dualcaster Mage + Corpse Dance

Thermopod

Dualcaster Mage

Corpse Dance

How it works

1. Cast Corpse Dance by paying its mana cost, targeting any applicable target.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Corpse Dance.
4. Holding priority, activate Thermopod by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Corpse Dance, with the copy targeting Dualcaster Mage
6. Resolve the Corpse Dance copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop hinges on recurring Dualcaster Mage to endlessly copy and recast Corpse Dance, feeding the entire engine. By leveraging Thermopod to sacrifice Dualcaster Mage for red mana right in response to its own enter-the-battlefield trigger, you easily fulfill the buyback cost of Corpse Dance while generating an excess of red mana. Each iteration relies on Corpse Dance pulling Dualcaster Mage right back out of the graveyard to copy the spell anew, creating a self-sustaining storm of sacrifices and spell copies.
