Ygra, Eater of All + Cauldron Familiar + Extruder + Teval, the Balanced Scale

Ygra, Eater of All

Cauldron Familiar

Extruder

Teval, the Balanced Scale

How it works

1. Activate Cauldron Familiar by sacrificing a Food.
2. Ygra triggers, putting two +1/+1 counters on it.
3. Resolve the Cauldron Familiar ability, returning it from your graveyard to the battlefield.
4. Cauldron Familiar and Teval trigger.
5. Resolve the Teval trigger, creating a creature token.
6. Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
7. Activate Extruder by sacrificing Cauldron Familiar.
8. When Cauldron Familiar dies, Ygra triggers, putting two +1/+1 counters on it.
9. Resolve the Extruder ability.
10. Repeat.

This loop transforms your battlefield into an engine of relentless recycling by turning every creature into a renewable resource. With Ygra, Eater of All actively converting every creature into a Food artifact in addition to its other types, Cauldron Familiar can sacrifice itself to its own recursion ability, feeding right back into the loop. Extruder steps in to handle that newly returned cat as an artifact sacrifice to fuel its +1/+1 counter distribution, all while Teval, the Balanced Scale rewards every single instance of cards leaving your graveyard by churning out a steady stream of 2/2 Zombie Druid tokens. Every iteration drains your opponents of their life total while growing your board to terrifying proportions.
