Beifong's Bounty Hunters + Shilgengar, Sire of Famine + Zendikar's Roil

Beifong's Bounty Hunters

Shilgengar, Sire of Famine

Zendikar's Roil

How it works

1. Activate Shilgengar by sacrificing another nonland creature you control.
2. When the creature dies, Beifong's Bounty Hunters triggers, earthbending a land.
3. Resolve the Shilgengar ability.
4. Activate Shilgengar by sacrificing the land.
5. When the land dies, Beifong's Bounty Hunters triggers, returning the land from your graveyard to the battlefield tapped.
6. When the land enters, Zendikar's Roil triggers, creating a creature token.
7. Resolve the Shilgengar ability.
8. Repeat.

This loop transforms Shilgengar, Sire of Famine into an engine of continuous sacrifice by turning lands into endlessly recurring fodder. When you feed a creature to Shilgengar's first ability, Beifong's Bounty Hunters responds by earthbending one of your lands into a 0/0 creature, which you can immediately sacrifice to Shilgengar in place of a regular creature. Because the earthbent land returns to the battlefield tapped whenever it dies, its reentry triggers Zendikar's Roil to produce a fresh Elemental creature token. You can then feed that new token back into Shilgengar, restarting the cycle to generate an endless cascade of Blood tokens, landfall triggers, and creature deaths.
