Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Woe Strider

The Immortal Sun

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 relies on a clever mana-positive engine to endlessly recur Priest of Gix, fueled in part by The Immortal Sun reducing its cost so it can be cast for just two mana from exile. Woe Strider acts as the sacrifice outlet that sends the Priest to the graveyard and enables the scry 1 utility, while Haunted Crossroads places the Priest back on top of your library just in time. Meanwhile, Rakdos, the Muscle watches every sacrifice and exiles your library card by card, letting you play everything you exile and generating a massive advantage.
