This loop turns a simple material sacrifice into an engine of exponential growth by feeding the output right back into the machinery. Krark-Clan Ironworks provides the initial engine room by breaking down artifacts for raw colorless mana, which in turn fuels the Automation Module's passive ability to spawn Servo tokens whenever counters arrive. That's where Crime Novelist steps in, transforming every single artifact sacrifice into both red mana and a +1/+1 counter on itself; because that counter placement triggers Animation Module, you can easily pay the required {1} to continuously generate fresh sacrifices and keep the cycle spinning.
