How it works
Cast Machine God's Effigy by paying 4. Choose to have it enter the battlefield as a copy of Technomancer.
When Machine God's Effigy enters, it triggers. Holding priority, activate Machine God's Effigy by tapping it, adding .
Activate Krark-Clan Ironworks by sacrificing Machine God's Effigy.
Resolve the Machine God's Effigy trigger, causing you to mill three cards and return Machine God's Effigy from your graveyard to the battlefield as a copy of Technomancer.
Repeat from step 2.
This looping engine relies on Machine God's Effigy entering as a copy of Technomancer, whose entry triggers a resurrection of cheap artifact creatures from the graveyard while milling your library. Because the copied Technomancer is itself an artifact, you can tap it for blue mana before sacrificing it to Krark-Clan Ironworks to generate a surplus of colorless mana. Each iteration recycles the cloned Technomancer back to the battlefield via its own triggered ability, allowing you to repeat the process indefinitely for an unbounded storm of mana, sacrifices, and graveyard recursion.
