Dino DNA + Krark-Clan Ironworks + Myr Battlesphere

Dino DNA

Krark-Clan Ironworks

Myr Battlesphere

How it works

1. Activate Dino DNA by paying 6, creating a token copy of Myr Battlesphere that is a 6/6 Dinosaur.
2. When the Myr Battlesphere token enters the battlefield, it triggers, creating four 1/1 Myr artifact creature tokens.
3. Activate Krark-Clan Ironworks three times by sacrificing three Myrs, adding six C.
4. Repeat.

This clever loop relies on Dino DNA to repeatedly birth a mechanical monstrosity, using its {6} activation to craft a token copy of Myr Battlesphere as a 6/6 Dinosaur. Each time that Battlesphere clone hits the battlefield, it floods your board with four 1/1 Myr artifact creature tokens to fuel the engine. You then feed three of those fresh Myrs to Krark-Clan Ironworks, converting them into six colorless mana to completely cover the cost of the next Dino DNA activation and leave you with a net profit of mana. Because Dino DNA can also hold other creatures under its imprint, this setup serves as an infinite mana and token factory that easily translates into victory in Commander, Legacy, Oathbreaker, and Vintage.
