Zirda, the Dawnwaker + Dino DNA + Power Artifact + Ashnod's Altar

Zirda, the Dawnwaker

Dino DNA

Power Artifact

Ashnod's Altar

How it works

1. Activate Dino DNA by paying 2, creating a token copy of a creature exiled with it that is a 6/6 Dinosaur.
2. Activate Ashnod's Altar by sacrificing the creature token, adding CC.
3. Repeat.

This clever loop leverages redundant cost-reduction effects from both Zirda, the Dawnwaker and Power Artifact to make the heavy {6} activation cost of Dino DNA remarkably cheap, dropping it down to just {2}. Once you pay that reduced price to churn out a 6/6 green Dinosaur token copy, you simply feed it directly to Ashnod's Altar to generate {C}{C}—which more than covers the activation cost and leaves you with surplus mana while generating infinite sacrifices, enters-the-battlefield triggers, and death triggers.
