How it works
Activate Eldrazi Displacer by paying 2C, blinking Precursor Golem.
When Precursor Golem enters the battlefield, it triggers, creating two 3/3 Golem artifact creature tokens.
Activate Krark-Clan Ironworks twice by sacrificing the Golems, adding CCCC.
Repeat.
Once you have infinite mana, you may forego sacrificing the Golems.
This loop turns the mechanical synergy between Eldrazi Displacer, Precursor Golem, and Krark-Clan Ironworks into a self-sustaining engine. By using Krark-Clan Ironworks to sacrifice the Golem tokens generated when Precursor Golem enters the battlefield, you easily recoup the colorless mana required to fuel Eldrazi Displacer's blink ability. Each iteration resets the process by returning Precursor Golem to the battlefield to flood the board with fresh tokens, allowing you to generate infinite colorless mana, death triggers, and creature enters-the-battlefield effects along the way.
