Tarrian's Soulcleaver + Scurry Oak + Carrion Feeder

Tarrian's Soulcleaver

Scurry Oak

Carrion Feeder

How it works

1. Put a +1/+1 counter on Scurry Oak.
2. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
3. Activate Carrion Feeder by sacrificing the Squirrel.
4. When the Squirrel dies, Tarrian's Soulcleaver triggers, putting a +1/+1 counter on Scurry Oak.
5. Scurry Oak triggers, creating a 1/1 Squirrel creature token.
6. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
7. Repeat from step 3.

This clever loop turns the natural synergy of +1/+1 counters and sacrifice into a self-sustaining engine. By using Carrion Feeder as a free outlet to sacrifice tokens, you clear the way for Tarrian's Soulcleaver to trigger each time a creature hits the graveyard. That death trigger places a +1/+1 counter directly back onto Scurry Oak, which immediately responds by spawning a fresh 1/1 Squirrel creature token to restart the cycle.
