Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Thunderscape Familiar

Phantom Train

How it works

1. Activate Phantom Train 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 Phantom Train 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 Phantom Train as a reliable outlet to repeatedly sacrifice Priest of Gix, fueling its sacrifice cost while letting Rakdos, the Muscle exile your library as you go. Thunderscape Familiar is the critical cost-reducer that makes casting the repeated Priest of Gix profitable, turning its initial three black mana into a surplus after accounting for the exile play cost. Meanwhile, Haunted Crossroads ensures you never run out of fodder by continuously recycling Priest of Gix from the graveyard back to the top of your library, right where Rakdos's exile ability can grab it again.
