Dualcaster Mage + Corpse Dance + Bartolomé del Presidio

Dualcaster Mage

Corpse Dance

Bartolomé del Presidio

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 Bartolomé del Presidio 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 brilliant loop centers on Dualcaster Mage copying Corpse Dance on the stack, creating a fresh copy of the Mage that enters the battlefield to repeat the process indefinitely. Bartolomé del Presidio is the essential sacrifice outlet that makes this engine repeatable, safely sending Dualcaster Mage back to the graveyard so Corpse Dance can target it once more. Because Corpse Dance relies on the top of your graveyard, sacrificing the Mage immediately ensures it is positioned to be brought right back, letting you continuously stack sacrifice and enter-the-battlefield triggers.
