Captain Storm, Cosmium Raider + Animation Module + Krark-Clan Ironworks

Captain Storm, Cosmium Raider

Animation Module

Krark-Clan Ironworks

How it works

1. Cause an artifact to enter the battlefield under your control.
2. Captain Storm triggers, putting a +1/+1 counter on a Pirate 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 the battlefield, Captain Storm triggers.
5. Holding priority, activate Krark-Clan Ironworks by sacrificing the Servo, adding CC.
6. Resolve the Captain Storm trigger, putting a +1/+1 counter on a Pirate you control.
7. Repeat from step 3.
8. Once you have infinite mana, you may forego sacrificing the Servos.

This clever loop turns the steady progression of counters into an unstoppable mechanical engine, legal in Commander, Legacy, Oathbreaker, and Vintage. It all starts when Captain Storm, Cosmium Raider buffs your chosen Pirate with a +1/+1 counter whenever an artifact enters the battlefield. That single counter placement immediately wakes up Animation Module, letting you pay a single mana to spawn a fresh 1/1 Servo artifact creature token. Because that Servo is an artifact entering the battlefield, it retriggers Captain Storm to keep the counter flowing, while Krark-Clan Ironworks stands ready to sacrifice that very same Servo for two colorless mana—easily funding Animation Module's fee and leaving you with an ever-growing surplus of mana, tokens, and counters.
