Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Umbral Collar Zealot

Rakdos, Lord of Riots

How it works

1. Activate Umbral Collar Zealot 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 Umbral Collar Zealot ability from step 1.
6. Cast Priest of Gix from exile by paying at most 2.
7. When Priest of Gix enters the battlefield, it triggers, adding .
8. Repeat.

This sinister loop relies on an engine of constant sacrifice and recursion, fueled entirely by the mana-producing capabilities of Priest of Gix. By feeding the priest to Umbral Collar Zealot, you trigger Rakdos, the Muscle, which not only grants the demon indestructible but also exiles cards from the top of your library to play for free. Before that exile resolves, Haunted Crossroads lets you spend black mana to neatly place the priest back on top of your library, ensuring it is waiting for you when you cast it from exile. Meanwhile, Rakdos, Lord of Riots sits quietly on the board, lowering the casting costs of your creatures so that the {B}{B}{B} generated by the entering priest easily covers the {2} cost to replay it, leaving you with infinite mana, triggers, and your entire library exiled to cast at your leisure.
