Animation Module + Krark-Clan Ironworks + The Destined White Mage + Virulent Emissary

Animation Module

Krark-Clan Ironworks

The Destined White Mage

Virulent Emissary

How it works

1. Gain life.
2. The Destined White Mage 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, Virulent Emissary triggers, causing you to gain life.
5. The Destined White Mage triggers. Holding priority, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
6. Resolve the The Destined White Mage trigger, putting a +1/+1 counter on a creature you control
7. Repeat from step 3.

This ingenious loop begins the moment you gain life, sparking The Destined White Mage to place a +1/+1 counter on your creature and waking up Animation Module to offer a Servo token for the low price of {1}. As that Servo enters the battlefield, Virulent Emissary catches the creature entry and hands you back the life you need to keep the cycle turning endlessly. To fuel this ongoing engine, Krark-Clan Ironworks steps in to sacrifice the newly minted Servo for a steady stream of colorless mana, paying for Animation Module's fee while generating a surplus of resources.
