Dino DNA + Power Artifact + Phyrexian Altar + Su-Chi

Dino DNA

Power Artifact

Phyrexian Altar

Su-Chi

How it works

1. Activate Dino DNA's second ability by paying 4, creating a token copy of Su-Chi that is a 6/6 Dinosaur.
2. Activate Phyrexian Altar by sacrificing the Su-Chi token, adding one mana of any color.
3. When the Su-Chi token dies, it triggers, adding CCCC.
4. Repeat.

This ingenious loop transforms a piece of prehistoric history into a self-sustaining mana engine, heavily discounted by Power Artifact so that Dino DNA’s token-creation ability costs a mere four mana instead of six. Once you use that ability to forge a 6/6 Dinosaur version of Su-Chi, you feed it straight into Phyrexian Altar to sacrifice the token for any color of mana. Because the Su-Chi token dies, its own death trigger fires and floods your pool with four colorless mana, leaving you with a net profit that lets you pay for Dino DNA all over again and repeat the process infinitely.
