Zirda, the Dawnwaker + Dino DNA + Phyrexian Altar + Su-Chi

Zirda, the Dawnwaker

Dino DNA

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 loop transforms your graveyard into an endless engine of prehistoric power, fueled by Zirda, the Dawnwaker's cost-reduction magic. Normally, activating Dino DNA's second ability to clone an exiled creature would cost a hefty {6}, but Zirda slashes that requirement down to just {4}, making the clone practically free to produce. Once your Su-Chi token enters the battlefield, you feed it directly to Phyrexian Altar to generate a colored mana of any choice. Because that sacrifice immediately triggers Su-Chi's own death ability, you get a massive payout of four colorless mana in return—leaving you with plenty of surplus energy to fund the next iteration and repeat the cycle infinitely.
