Activate Emiel the Blessed by paying 3, blinking Bill the Pony.
When Bill the Pony enters the battlefield, it triggers, creating two Food artifact tokens.
Activate Krark-Clan Ironworks twice by sacrificing the Foods, adding CCCC.
Repeat.
Once you have infinite mana, you may forego sacrificing the Foods.
This clever loop relies on Bill the Pony to seed the battlefield with two Food tokens the moment it enters, which Krark-Clan Ironworks can eagerly dismantle for four colorless mana. By funneling three of that mana into Emiel the Blessed, you exile and return Bill to the battlefield to repeat the cycle, netting a surplus of colorless mana with every iteration. Because Emiel's ability keeps churning out endless creature triggers, you can continually generate infinite artifacts, life, and blinks at your leisure.
