K'rrik, Son of Yawgmoth + Pontiff of Blight + Gravecrawler + Carrion Feeder

K'rrik, Son of Yawgmoth

Pontiff of Blight

Gravecrawler

Carrion Feeder

How it works

1. Activate Carrion Feeder by sacrificing Gravecrawler, putting a +1/+1 counter on Carrion Feeder.
2. Cast Gravecrawler from your graveyard by paying or 2 life due to K'rrik.
3. K'rrik triggers, as well as each creature you control's extort ability.
4. Resolve the first K'rrik trigger, putting a +1/+1 counter on it.
5. Resolve the first extort trigger, causing you to pay W/B or 2 life due to K'rrik, causing each opponent to lose 1 life and you to gain that much life.
6. Repeat step 5 for each remaining trigger.
7. Repeat from step 1.

This loop turns Carrion Feeder and Gravecrawler into an endless recycling engine, where the relentless skeleton is repeatedly sacrificed and recast from the graveyard. While Gravecrawler provides the cheap recurring creature, K'rrik, Son of Yawgmoth steps in to completely bypass the black mana requirement by letting you pay life instead, keeping the loop running even when your mana is tapped out. Meanwhile, Pontiff of Blight grants extort to your board, multiplying every single casting into a flurry of life drains that effortlessly offset the life you spent on K'rrik's ability.
