Lyla triggers, putting a +1/+1 counter on a creature you control.
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, Tresserhorn's Lord triggers, causing you to draw a card.
Repeat from step 2.
This clever loop gets its engine running whenever you draw a card, which causes Lyla, Holographic Assistant to place a +1/+1 counter on a creature. That counter immediately triggers Animation Module, allowing you to pay a single mana to create a 1/1 Servo artifact creature token. You then feed that Servo to Krark-Clan Ironworks, which sacrifices the artifact to generate two colorless mana—more than enough to pay for the Module's trigger while netting extra resources. Finally, the sacrifice triggers Tresserhorn's Lord, Returned, which lets you draw a card to restart the entire sequence from the top.
