How it works
Activate Arcbound Ravager by sacrificing Sword of the Meek, putting a +1/+1 counter on it.
Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
When the Servo enters, Sword of the Meek triggers, returning itself from your graveyard to the battlefield attached to the Servo.
Activate Ashnod's Altar by sacrificing the Servo, adding CC.
Repeat.
This clever loop turns the graveyard and battlefield into a seamless cycle of recycling and sacrifice. By using Ashnod's Altar to generate colorless mana, you can easily pay for Animation Module's trigger whenever Arcbound Ravager places a +1/+1 counter by sacrificing Sword of the Meek. The resulting 1/1 Servo artifact creature token entering the battlefield immediately triggers Sword of the Meek to pull itself back out of your graveyard and attach to the new token, which is then fed right back into Ashnod's Altar to sustain the loop.
