Bristlebud Farmer + Krark-Clan Ironworks + Eldrazi Displacer

Bristlebud Farmer

Krark-Clan Ironworks

Eldrazi Displacer

How it works

1. Activate Eldrazi Displacer by paying 2C, blinking Bristlebud Farmer.
2. When Bristlebud Farmer enters the battlefield, its first ability triggers, creating two Food artifact tokens.
3. Activate Krark-Clan Ironworks twice by sacrificing the Foods, adding CCCC.
4. Repeat.

This elegant loop relies on Krark-Clan Ironworks to convert the raw materials generated by Bristlebud Farmer into the fuel needed to keep the cycle going. When Eldrazi Displacer blinks Bristlebud Farmer, the plant beast's entrance triggers the creation of two fresh Food tokens, which Krark-Clan Ironworks gladly breaks down for four colorless mana. Since Eldrazi Displacer only asks for three mana to reset the process, you are left with a net gain of colorless mana with every iteration, letting you repeat the trick indefinitely to flood the board with endless creature enters-the-battlefield triggers.
