Animation Module + Krark-Clan Ironworks + Light of Promise + Social Climber

Animation Module

Krark-Clan Ironworks

Light of Promise

Social Climber

How it works

1. Gain life.
2. The creature with Light of Promise attached triggers, putting a +1/+1 counter on it.
3. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
4. When the Servo enters, Social Climber triggers, causing you to gain life.
5. The creature with Light of Promise attached triggers. Holding priority, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
6. Resolve the trigger from the creature with Light of Promise attached, putting a +1/+1 counter on it
7. Repeat from step 3.

This elegant engine turns a single spark of life into an unstoppable cascade of growth and mana. It all centers around the creature enchanted by Light of Promise, which responds to any lifegain by piling on +1/+1 counters to fuel Animation Module's trigger; paying the single mana required creates a Servo token that immediately trips Social Climber to gain you life all over again. To sustain this loop, Krark-Clan Ironworks steps in to sacrifice that newly minted Servo for colorless mana, effortlessly funding the Animation Module while generating a surplus of infinite resources along the way.
