Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Umbral Collar Zealot

Sifter of Skulls

How it works

1. Activate Umbral Collar Zealot by sacrificing Priest of Gix.
2. When Priest of Gix dies, Sifter of Skulls and Rakdos trigger.
3. Resolve the Sifter of Skulls trigger, creating a 1/1 Eldrazi Scion creature token.
4. Holding priority, activate Haunted Crossroads by paying , putting Priest of Gix from your graveyard onto the top of your library.
5. 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.
6. Resolve the Umbral Collar Zealot ability from step 1, putting a +1/+1 counter on it.
7. Activate the Eldrazi Scion by sacrificing it, adding C.
8. Cast Priest of Gix from exile by paying 3.
9. When Priest of Gix enters the battlefield, it triggers, adding .
10. Repeat.

This loop is a masterclass in recycling, turning the mana-generating ETB of Priest of Gix into an engine that churns through your entire deck. Sifter of Skulls acts as the vital production line, replacing your sacrificed creatures with Eldrazi Scion tokens that provide the colorless mana needed to recast the Priest from exile. Meanwhile, Umbral Collar Zealot handles the sacrifice outlet, while Haunted Crossroads neatly loops the Priest right back to the top of your library to be exiled by Rakdos, the Muscle. As Rakdos triggers off every sacrifice, you'll chew through your opponent's library and exile your own deck with the freedom to cast everything you find.
