Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Bartolomé del Presidio

Honest Rutstein

How it works

1. Activate Bartolomé del Presidio by sacrificing Priest of Gix.
2. When Priest of Gix dies, Rakdos triggers.
3. Holding priority, activate Haunted Crossroads by paying , putting Priest of Gix from your graveyard onto the top of your library.
4. Resolve the Rakdos trigger, causing you to exile the top three cards of your library with the ability to play them until your next end step.
5. Resolve the Bartolomé del Presidio ability from step 1.
6. Cast Priest of Gix from exile by paying 2.
7. When Priest of Gix enters the battlefield, it triggers, adding .
8. Repeat.

This clever loop uses Rakdos, the Muscle to exile your entire library while generating infinite death triggers and counters, all fueled by the mana from Priest of Gix. By sacrificing the Priest to Bartolomé del Presidio, you trigger Rakdos to exile cards off the top of your library and immediately respond with Haunted Crossroads to tuck the Priest right back onto your library so it can be cast again. Thanks to Honest Rutstein reducing creature spell costs by {1}, casting the Priest from exile costs just {2}, allowing the black mana it produces upon entering to completely sustain the loop while Bartolomé grows infinitely large with +1/+1 counters.
