How it works
Gain life.
Spider-Man 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.
When the Servo enters, Lunarch Veteran triggers if it's on the battlefield.
Regardless, activate Phyrexian Altar by sacrificing the Servo, adding 1
When the Servo dies, Luminous Phantom triggers if it's on the battlefield.
Resolve either the Lunarch Veteran or Luminous Phantom trigger, causing you to gain life
Spider-Man triggers, putting a +1/+1 counter on a creature you control.
Repeat from step 3.
This elegant loop spins up by leveraging Spider-Man, Peter Parker to turn any instance of lifegain into a +1/+1 counter, which in turn wakes up Animation Module to birth a fresh Servo artifact token for a single mana. You can then feed that Servo straight into Phyrexian Altar to generate the exact mana needed to pay for the Module's trigger, while its death gracefully feeds Lunarch Veteran // Luminous Phantom to gain life and restart the whole chain. It's a wonderful closed-circuit engine where every piece—from the counter-generation to the mana filtering and the life triggers—locks together to yield infinite lifegain, death triggers, and counters.
