Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Carrion Feeder

Cemetery Prowler

How it works

1. Activate Carrion Feeder 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 Carrion Feeder 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 loop transforms a simple recursion engine into an overwhelming display of demonic value. Carrion Feeder acts as the sacrifice outlet, letting you feed Priest of Gix to the grave, where Haunted Crossroads immediately tucks it back onto the top of your library for a single black mana. Meanwhile, Cemetery Prowler quietly acts as the cost-reducer, shaving the generic mana off Priest of Gix so that its enter-the-battlefield mana generation completely covers the casting cost from exile and leaves you with surplus black mana. As you cycle the Priest through this loop, Rakdos, the Muscle triggers on every single sacrifice to exile your entire library card by card, granting you access to play your whole deck while growing Carrion Feeder into an endlessly massive threat.
