Animation Module + Ashnod's Altar + Ajani's Welcome + Spider-Man, Peter Parker

Animation Module

Ashnod's Altar

Ajani's Welcome

Spider-Man, Peter Parker

How it works

1. Gain life.
2. Spider-Man triggers, putting a +1/+1 counter on a creature you control.
3. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
4. When the Servo enters, Ajani's Welcome triggers, causing you to gain life.
5. Spider-Man triggers. Holding priority, activate Ashnod's Altar by sacrificing the Servo, adding CC.
6. Resolve the Spider-Man trigger, putting a +1/+1 counter on a creature you control.
7. Repeat from step 3.

This elegant loop turns a single instance of lifegain into an infinitely self-sustaining engine. It all begins when you gain life, triggering Spider-Man, Peter Parker to place a +1/+1 counter on a creature you control. That counter placement wakes up Animation Module, letting you pay a single mana to spawn a 1/1 Servo artifact creature token. The moment that Servo enters the battlefield, Ajani's Welcome grants you life, which seamlessly restarts Spider-Man, Peter Parker's trigger. Finally, Ashnod's Altar provides the colorless mana needed to pay Animation Module's fee by sacrificing the newly minted Servo, leaving you with infinite life, mana, and counters.
