Feral Ghoul + Animation Module + Thermopod

Feral Ghoul

Animation Module

Thermopod

How it works

1. Activate Thermopod by sacrificing an additional creature, adding at least one mana.
2. When the creature dies, Feral Ghoul's first ability triggers, 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. Repeat.
5. Once you have infinite +1/+1 counters on Feral Ghoul, you may sacrifice it to give opponents infinite rad counters, which will cause them to mill their library and lose a large amount of life during their next precombat main phase.

This brilliant setup turns a simple sacrifice loop into an unstoppable engine, fueled by Thermopod's ability to turn any departed creature into precious red mana. Whenever a creature meets its end, Feral Ghoul grows stronger from the loss, triggering Animation Module to immediately forge a brand new 1/1 Servo artifact creature token for a single mana. That freshly minted Servo can then be sacrificed right back into Thermopod to sustain the cycle, continuously pumping up Feral Ghoul with an endless stream of +1/+1 counters. Once your ghoul has achieved astronomical power, sending it to the graveyard allows its final trigger to flood your opponents with a staggering amount of rad counters, dooming them to mill their libraries and wither away into defeat.
