Bartolomé del Presidio + Animation Module + Mana Echoes

Bartolomé del Presidio

Animation Module

Mana Echoes

How it works

1. Activate Bartolomé del Presidio by sacrificing another creature, 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 the battlefield, Mana Echoes triggers, adding C for each Servo on the battlefield.
4. Repeat.
5. If there is at least one other Servo on the battlefield to start the combo and/or you have an additional 1 available with an additional creature, this combo nets infinite colorless mana.

This clever loop transforms a humble sacrifice into a self-sustaining engine by chaining together triggers from artifacts and creatures alike. You begin by feeding a creature to Bartolomé del Presidio, whose sacrificial act places a +1/+1 counter on himself and immediately wakes up Animation Module's triggered ability. Paying the required mana creates a fresh Servo artifact creature token, which in turn causes Mana Echoes to flood your pool with colorless mana based on the growing number of Servos on the battlefield. That newly generated mana pays to keep Animation Module's trigger going, letting you sacrifice the token back to Bartolomé del Presidio to repeat the cycle while generating an arbitrary amount of mana, counters, and triggers.
