How it works
Activate Dino DNA by paying 6, creating a token copy of Su-Chi Cave Guard that is a 6/6 Dinosaur.
Activate Carrion Feeder by sacrificing the Su-Chi Cave Guard token.
When the Su-Chi Cave Guard token dies, it triggers, adding eight C.
Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
Repeat.
Once you have infinite mana, you may forego sacrificing the Su-Chi Cave Guard tokens.
This loop relies on transforming graveyard recursion into a self-sustaining engine by turning Su-Chi Cave Guard into a massive 6/6 Dinosaur using Dino DNA's imprint and creation ability. Once that token is on the battlefield, you feed it to Carrion Feeder; the death trigger yields eight colorless mana—more than enough to pay the {6} activation cost to make a fresh copy with Dino DNA and still profit two mana each iteration. Carrion Feeder gladly accepts the sacrifices to grow larger with infinite +1/+1 counters, leaving you with an unstoppable swarm of tokens and boundless resources.
