Sword of the Meek + Animation Module + Krark-Clan Ironworks + Carrion Feeder

Sword of the Meek

Animation Module

Krark-Clan Ironworks

Carrion Feeder

How it works

1. Activate Krark-Clan Ironworks by sacrificing Sword of the Meek, adding CC.
2. Activate Carrion Feeder by sacrificing another creature, 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, Sword of the Meek triggers, returning itself from your graveyard to the battlefield attached to the Servo.
5. Repeat.

This clever loop is powered by Krark-Clan Ironworks, which sacrifices Sword of the Meek to generate a surplus of colorless mana while sending the Equipment straight to the graveyard. That sacrifice feeds Carrion Feeder, whose ability not only consumes a creature to grow larger but also places a +1/+1 counter on it. The moment that counter lands, Animation Module springs to life, letting you pay a single mana to spawn a 1/1 Servo artifact creature token. As that Servo enters the battlefield, Sword of the Meek triggers from your graveyard to reattach itself to the new token, perfectly resetting the loop and leaving you with infinite mana, counters, and artifact sacrifices.
