Beifong's Bounty Hunters + Gravecrawler + Bloodflow Connoisseur + Archelos, Lagoon Mystic

Beifong's Bounty Hunters

Gravecrawler

Bloodflow Connoisseur

Archelos, Lagoon Mystic

How it works

1. Activate Bloodflow Connoisseur by sacrificing Gravecrawler.
2. When Gravecrawler dies, Beifong's Bounty Hunters triggers, earthbending a land that can tap to produce at least .
3. Resolve the Bloodflow Connoisseur ability.
4. Activate Bloodflow Connoisseur by sacrificing the land.
5. When the land dies, Beifong's Bounty Hunters triggers, returning the land from your graveyard to the battlefield untapped due to Archelos.
6. Resolve the Bloodflow Connoisseur ability.
7. Activate the land by tapping it, adding at least .
8. Cast Gravecrawler from your graveyard by paying .
9. Repeat.

This clever loop turns graveyard recursion into a self-sustaining engine by letting a land double as a sacrificial engine and a mana source. With Bloodflow Connoisseur ready to devour your permanents for power, Gravecrawler provides the initial fuel while benefiting from the Zombie type that lets it repeatedly crawl out of your graveyard. Meanwhile, Beifong's Bounty Hunters transforms your lands into resilient threats whenever a creature dies, turning those land-creatures into expendable fodder that returns to the battlefield when they perish. The brilliance of the setup is completed by Archelos, Lagoon Mystic, whose passive ability ensures that lands brought back by the Bounty Hunters enter the battlefield untapped rather than tapped, allowing you to immediately tap them for the black mana needed to recast Gravecrawler and repeat the cycle indefinitely.
