Exhume + Dualcaster Mage + Bartolomé del Presidio

Exhume

Dualcaster Mage

Bartolomé del Presidio

How it works

1. Cast Exhume by paying its mana cost
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Exhume.
4. Holding priority, activate Bartolomé del Presidio by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Exhume
6. Resolve the Exhume copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This looping engine centers on casting Exhume to pull Dualcaster Mage back from the graveyard, utilizing the mage's enter-the-battlefield ability to continually copy the original sorcery. To keep the loop going, Bartolomé del Presidio acts as the sacrificial outlet that bins Dualcaster Mage right back into the graveyard in response to its own copy trigger, while simultaneously growing larger with each iteration thanks to its +1/+1 counter ability. Because Exhume forces every player to participate, this setup not only fuels endless sacrifice and death triggers for your own board, but also lets your opponents recur their entire creature graveyards along the way.
