Oltec Matterweaver + Ancestral Statue + Krark-Clan Ironworks + Academy Manufactor

Oltec Matterweaver

Ancestral Statue

Krark-Clan Ironworks

Academy Manufactor

How it works

1. Cast Ancestral Statue by paying 4
2. Oltec Matterweaver triggers, creating a Food, a Clue and a Treasure artifact 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 two artifact tokens, adding CCCC.
5. Repeat.
6. Once you have infinite mana, you may target any other token you control using Oltec Matterweaver's trigger, or create Gnomes instead.

This intricate loop relies on an endless cycle of casting and returning Ancestral Statue to generate a massive surplus of resources, fueled entirely by the mana from Krark-Clan Ironworks. Each time you recast the Statue, Oltec Matterweaver triggers to duplicate your artifact tokens, while Academy Manufactor magnifies every single Clue, Food, or Treasure into a full trio of tokens. By feeding those generated tokens back into Krark-Clan Ironworks, you easily recoup more than enough colorless mana to recast the Statue, letting you repeat the process indefinitely for an unstoppable cascade of artifact and creature triggers.
