Rakdos, the Muscle + Priest of Gix + Haunted Crossroads + Goblin Bombardment + Pawn of Ulamog

Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Goblin Bombardment

Pawn of Ulamog

How it works

1. Activate Goblin Bombardment by sacrificing Priest of Gix.
2. When Priest of Gix dies, Pawn of Ulamog and Rakdos trigger.
3. Resolve the Pawn of Ulamog trigger, creating a 0/1 Eldrazi Spawn creature token.
4. Holding priority, activate Haunted Crossroads by paying , putting Priest of Gix from your graveyard onto the top of your library.
5. 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.
6. Resolve the Goblin Bombardment ability from step 1, dealing 1 damage to any target.
7. Activate the Eldrazi Spawn by sacrificing it, adding C.
8. Cast Priest of Gix from exile by paying 3.
9. When Priest of Gix enters the battlefield, it triggers, adding .
10. Repeat.

This elegant loop centers on casting Priest of Gix repeatedly, turning its initial mana burst into an engine of absolute destruction. With Pawn of Ulamog and Goblin Bombardment providing the sacrifice outlet and a steady stream of Eldrazi Spawn tokens, Haunted Crossroads conveniently tucks the Priest right back onto your library. Meanwhile, Rakdos, the Muscle capitalizes on every single sacrifice by chewing through your library and exiling cards so you can play them using the mana generated by the Priest and your tokens.
