Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Goblin Bombardment

Cemetery Prowler

How it works

1. Activate Goblin Bombardment 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 Goblin Bombardment 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 vicious loop transforms the humble Priest of Gix into an infinite engine of destruction by leveraging Goblin Bombardment to sacrifice it while Rakdos, the Muscle triggers to exile your library, letting you play everything you uncover. The key to making this mana-positive is Cemetery Prowler, whose static ability reduces the cost of creature spells by {1} for each shared card type with its exiled cards—dropping the priest's casting cost from {3} down to just {2}. With that discount, the black mana generated upon re-entry more than covers the cost, leaving you free to use Haunted Crossroads to loop the priest right back to the top of your library for a single black mana.
