Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Planar Gate

Bloodflow Connoisseur

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, putting a +1/+1 counter on it.
6. Cast Priest of Gix from exile by paying 2.
7. When Priest of Gix enters the battlefield, it triggers, adding .
8. Repeat.

This clever loop turns the graveyard into your personal hand while generating an endless stream of black mana and sacrifice triggers. By using Bloodflow Connoisseur to feed Priest of Gix to Rakdos, the Muscle, you trigger Rakdos's exile ability to peel cards off your library—including the very Priest you just sent away. Haunted Crossroads neatly sets up that topdeck recursion for a single black mana, while Planar Gate steps in to discount the casting cost so that the {B}{B}{B} generated by Priest of Gix more than covers the expenses, leaving you with infinite mana and counters to seal the game.
