Rakdos, the Muscle

Priest of Gix

Haunted Crossroads

Bloodflow Connoisseur

Ezzaroot Channeler

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 at most 2.
7. When Priest of Gix enters the battlefield, it triggers, adding .
8. Repeat.

This clever loop uses Bloodflow Connoisseur as the sacrificial outlet to feed Priest of Gix back into the graveyard, while Haunted Crossroads puts that same priest right back on top of your library for cheap. Because Ezzaroot Channeler's tap ability nets you 2 life, its passive cost-reduction engine kicks in to discount creature spells by {2}, allowing you to recast the Priest for a single black mana using the {B}{B}{B} generated by its own entrance trigger. Meanwhile, Rakdos, the Muscle watches every single sacrifice happen, systematically exiling your entire library card by card so you can cast every spell you own with any type of mana.
