Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Bloodflow Connoisseur

The Immortal Sun

How it works

1. Activate Bloodflow Connoisseur 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 Bloodflow Connoisseur 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 uses Bloodflow Connoisseur as the sacrificial outlet to feed Priest of Gix back into the graveyard, while Haunted Crossroads conveniently recycles the Priest right back to the top of your library. From there, Rakdos, the Muscle catches the Priest's departure and exiles your library card by card, granting you the freedom to cast those exiled spells using the mana generated by the Priest's entry trigger. Meanwhile, The Immortal Sun quietly reduces your casting costs by {1} to ensure the math on recasting Priest of Gix works seamlessly, while also pumping your board with a static buff.
