Ygra, Eater of All + Camellia, the Seedmiser + Extruder

Ygra, Eater of All

Camellia, the Seedmiser

Extruder

How it works

1. Activate Extruder by sacrificing any other creature.
2. Because the creature is a Food due to Ygra, when it dies, Camellia and Ygra trigger.
3. Resolve the Ygra trigger, putting two +1/+1 counters on it.
4. Resolve the Camellia trigger, creating a 1/1 Squirrel creature token.
5. Resolve the Extruder ability, putting a +1/+1 counter on a creature you control.
6. Repeat.

This loop turns your entire board into a self-sustaining engine by letting Extruder sacrifice any creature to fuel itself. Thanks to Ygra, Eater of All, every single creature you control is simultaneously a Food artifact, meaning tossing one to Extruder's ability triggers a cascade of permanent growth. Camellia, the Seedmiser capitalizes on this carnage by spinning up a brand new 1/1 green Squirrel creature token every time a Food bites the dust, providing endless fodder to keep the cycle going. As those sacrifices pile up, Ygra, Eater of All rewards the graveyard trip by permanently ballooning in size with two +1/+1 counters per iteration, while Extruder can distribute its own counters to keep your token army threatening.
