How it works
Activate Junk Golem by paying 1 and discarding a card, putting a +1/+1 counter on it.
Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
Activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
When the Servo dies, Fecundity triggers, causing you to draw a card.
Repeat.
This engine turns your hand into a boundless engine of recycling and card advantage by feeding on Junk Golem's repeatable counter-placement. Animation Module acts as the crucial linchpin, translating the application of those +1/+1 counters into a steady stream of artifact creatures that you can immediately sacrifice to Krark-Clan Ironworks for mana. Every time one of those tokens meets its end, Fecundity springs into action to replace the discarded card in your hand, keeping the loop fueled as long as you have cards to pitch.
