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 Ashnod's Altar by sacrificing the Servo, adding CC.
When the Servo dies, Liliana, Dreadhorde General triggers, causing you to draw a card.
Repeat from step 2.
This ingenious loop relies on a self-sustaining cycle of card draw and token creation powered by your graveyard. By utilizing Lyla, Holographic Assistant to turn every drawn card into a +1/+1 counter, you trigger Animation Module to produce a Servo token for a single mana. You can then feed that Servo to Ashnod's Altar to generate the {C}{C} needed to sustain the loop while netting extra colorless mana, which in turn causes Liliana, Dreadhorde General to draw you a fresh card whenever the sacrificed creature dies.
