Bill the Pony + Eldrazi Displacer + Krark-Clan Ironworks

Bill the Pony

Eldrazi Displacer

Krark-Clan Ironworks

How it works

1. Activate Eldrazi Displacer by paying 2C, blinking Bill the Pony.
2. When Bill the Pony enters the battlefield, it triggers, creating two Food artifact tokens.
3. Activate Krark-Clan Ironworks twice by sacrificing the Foods, adding CCCC.
4. Repeat.
5. Once you have infinite mana, you may forego sacrificing the Foods.

This clever loop is fueled by Eldrazi Displacer, which pays for its own activation by repeatedly blinking Bill the Pony to harvest a fresh crop of artifact tokens. Each time Bill the Pony re-enters, its triggered ability generates two Food tokens that feed right into Krark-Clan Ironworks, converting them into the colorless mana needed to keep the Displacer's ability running indefinitely. Because Krark-Clan Ironworks yields four mana per blink cycle while Eldrazi Displacer only demands three, you generate a surplus of infinite colorless mana along with boundless creature entry triggers and Food tokens.
