Thermopod + Dualcaster Mage + Sevinne's Reclamation

Thermopod

Dualcaster Mage

Sevinne's Reclamation

How it works

1. Cast Sevinne's Reclamation 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 Sevinne's Reclamation.
4. Holding priority, activate Thermopod by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Sevinne's Reclamation, with the copy targeting Dualcaster Mage
6. Resolve the Sevinne's Reclamation copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop lets you endlessly recur and sacrifice Dualcaster Mage by harnessing its own copied triggers. When Dualcaster Mage enters the battlefield to copy Sevinne's Reclamation, you sacrifice it to Thermopod for red mana, letting the resolving copy bring Dualcaster Mage right back from the graveyard. Because Sevinne's Reclamation fuels the entire process and provides the recursive engine, you can repeat this sequence indefinitely to generate an infinite supply of red mana alongside boundless creature entry, death, and sacrifice triggers.
