Animation Module + Skyknight Squire + Krark-Clan Ironworks

Animation Module

Skyknight Squire

Krark-Clan Ironworks

How it works

1. Put a +1/+1 counter on a creature you control.
2. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
3. When the Servo enters the battlefield, Skyknight Squire triggers, putting a +1/+1 counter on it.
4. Animation Module triggers, holding priority, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
5. Resolve the Animation Module trigger, causing you to pay 1 to create a 1/1 Servo artifact creature token.
6. Repeat from step 3.

This loop creates a self-sustaining engine by turning the creation of artifact tokens into a resource-generating cycle. When you put a +1/+1 counter on Skyknight Squire, Animation Module triggers to let you pay {1} for a Servo artifact creature token, which in turn triggers Skyknight Squire again to grow larger. You can then sacrifice that very Servo to Krark-Clan Ironworks for two generic mana—more than enough to pay for Animation Module's triggered ability and keep the entire assembly line running indefinitely.
