How it works
Activate Krark-Clan Ironworks by sacrificing any other creature you control, adding CC.
Sandbender Scavengers triggers, putting a +1/+1 counter on it.
Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
Repeat.
This clever loop turns a modest sacrifice outlet into a self-sustaining engine by capitalizing on cascading triggers. By leveraging Krark-Clan Ironworks to sacrifice a creature for mana, you feed Sandbender Scavengers the death it needs to grow a +1/+1 counter, which in turn wakes up Animation Module to pay for a fresh Servo artifact creature token. That newly minted Servo can immediately be sacrificed back to Krark-Clan Ironworks to fuel Animation Module's fee, yielding infinite colorless mana and an endlessly growing army of tokens and counters.
