Sword of the Meek + Animation Module + Thermopod + Phantom Train

Sword of the Meek

Animation Module

Thermopod

Phantom Train

How it works

1. Activate Phantom Train by sacrificing Sword of the Meek, putting a +1/+1 counter on it.
2. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
3. When the Servo enters, Sword of the Meek triggers, returning itself from your graveyard to the battlefield attached to the Servo.
4. Activate Thermopod by sacrificing the Servo, adding .
5. Repeat.

This intricate loop relies on Phantom Train to fuel the cycle by sacrificing Sword of the Meek, which adds a crucial +1/+1 counter to the Vehicle and sparks the whole engine. That counter immediately triggers Animation Module, letting you pay a single mana to create a 1/1 Servo artifact creature token. The moment that Servo enters, Sword of the Meek triggers from your graveyard to resurrect itself and attach directly to the new token. Finally, Thermopod steps in as the sacrifice outlet, converting your newly minted Servo into red mana to pay for Animation Module's trigger and keep the loop spinning indefinitely.
