Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Woe Strider

Honest Rutstein

How it works

1. Activate Woe Strider 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 Woe Strider 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 uses Woe Strider to feed Priest of Gix to Rakdos, the Muscle, triggering Rakdos's exile ability while simultaneously setting up the mana and recursion needed to keep going. Honest Rutstein's cost reduction helps make recasting the priest affordable, while Haunted Crossroads steps in to fish the priest right back onto the top of your library in response to Rakdos's trigger so you can exile and replay it. Because you are repeatedly casting and sacrificing the priest, you generate endless mana and death triggers while chewing through your library to exile every single card with permission to play them all until your next end step.
