How it works
Activate Ashnod's Altar by sacrificing a creature, adding CC.
When the creature dies, Sephiroth, Fabled SOLDIER // Sephiroth, One-Winged Angel triggers, causing you to gain 1 life and an opponent to lose 1 life.
Lisette triggers, causing you to pay 1 to put a +1/+1 counter on each creature you control.
Animation Module triggers for each counter placed this way.
Resolve the first trigger, choosing to pay 1 to create a 1/1 Servo artifact creature token.
