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 Bloodthrone Vampire ability from step 1.
6. Cast Priest of Gix from exile by paying at most 2.

8. Repeat.

This loop spins up into infinity by recycling Priest of Gix through the graveyard and back onto the battlefield, fueled by the mana it generates upon entry.

While Bloodthrone Vampire provides the necessary sacrifice outlet to keep the cycle turning, Heliod, the Radiant Dawn // Heliod, the Warped Eclipse shapes the economics of the whole operation by reducing spell costs and granting flash.
