Dualcaster Mage + Carrion Feeder + Lively Dirge

Dualcaster Mage

Carrion Feeder

Lively Dirge

How it works

1. Cast Lively Dirge by paying 1 plus an additional 2 to select its second mode, targeting a card in your graveyard.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Lively Dirge.
4. Holding priority, activate Carrion Feeder by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Lively Dirge
6. Resolve the Lively Dirge copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This clever loop leverages Lively Dirge's spree ability to return creatures to the battlefield, setting up a recursive engine where Dualcaster Mage endlessly copies the spell while entering and leaving the graveyard. By sacrificing the Mage to Carrion Feeder in response to its own copy trigger, you feed the Feeder's appetite while ensuring the next iteration of Lively Dirge can pull the Dualcaster Mage right back out of the graveyard to repeat the cycle.
