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 Phyrexian Altar by sacrificing the Servo, adding one mana of any color.
When the Servo dies, Weatherlight Compleated triggers, putting a phyresis counter on it and causing you to draw a card.
Repeat from step 2.
This clever loop uses Lyla, Holographic Assistant to bridge card draw and permanent growth, turning every card drawn into the seed of an automated factory. When Lyla places a +1/+1 counter in response to drawing, Animation Module happily steps in to convert that counter into a 1/1 Servo artifact creature token for the low cost of {1}. That Servo is immediately fed to Phyrexian Altar, generating the exact mana needed to pay Animation Module's trigger while simultaneously triggering Weatherlight Compleated. As Weatherlight Compleated accumulates phyresis counters from the dying creature, its final ability draws you a fresh card once it hits seven counters—or keeps your draws flowing with scrys earlier on—restarting the entire cycle and fueling your engine indefinitely.
