Oltec Matterweaver + Ancestral Statue + Krark-Clan Ironworks + Worldwalker Helm

Oltec Matterweaver

Ancestral Statue

Krark-Clan Ironworks

Worldwalker Helm

How it works

1. Cast Ancestral Statue by paying 4
2. Oltec Matterweaver triggers, creating a 1/1 Gnome artifact creature token and a Map token.
3. When Ancestral Statue enters the battlefield, it triggers, returning itself from the battlefield to your hand.
4. Activate Krark-Clan Ironworks by sacrificing the Gnome and Map, adding CCCC.
5. Repeat.

This looping mechanism relies on Oltec Matterweaver's triggered ability to exploit the self-bouncing nature of Ancestral Statue, generating a steady stream of artifact tokens whenever you cast the Statue. As those tokens flood the board, Krark-Clan Ironworks steps in as the engine's powerhouse, converting your accumulated artifacts into the colorless mana needed to recast the Statue over and over. Meanwhile, Worldwalker Helm acts as a crucial amplifier for your token production by constantly sliding extra Map tokens into the mix, ensuring you always net a surplus of mana from every iteration through the Ironworks.
