Dualcaster Mage + Extract from Darkness + Carrion Feeder

Dualcaster Mage

Extract from Darkness

Carrion Feeder

How it works

1. Cast Extract from Darkness by paying its mana cost
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Extract from Darkness.
4. Holding priority, activate Carrion Feeder by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Extract from Darkness
6. Resolve the Extract from Darkness copy, causing each player to mill two cards and returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This brilliant loop turns a single spell into an infinite graveyard engine by using Dualcaster Mage's entry trigger to perpetually copy Extract from Darkness. Because Extract from Darkness resurrects a creature from the graveyard as part of its resolution, it conveniently brings back the very same Dualcaster Mage you just lost, while also steadily milling both players along the way. To keep the chain from fizzling or clogging your board, Carrion Feeder acts as the essential sacrifice outlet, letting you neatly dispose of Dualcaster Mage at instant speed to fuel an endless cycle of death triggers, counters, and rising power.
