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 1.
When the Servo dies, Dragon Appeasement triggers, causing you to draw a card.
Repeat from step 2.
This clever loop turns the mere act of drawing a card into a self-sustaining engine of creation and sacrifice. With Dragon Appeasement skipping your draw step to neatly sidestep decking yourself, its sacrifice trigger instead fuels your engine by letting you draw a card whenever a creature goes to the graveyard. That draw immediately wakes up Lyla, Holographic Assistant, whose passive trigger places a +1/+1 counter on a creature to pay forward into Animation Module's token-making ability. Finally, the Servo token created along the way is fed directly into Phyrexian Altar, generating the exact mana needed to pay for the Module while feeding the very sacrifice trigger Dragon Appeasement needs to keep the cards flowing.
