Tarrian's Soulcleaver + Animation Module + Ashnod's Altar

Tarrian's Soulcleaver

Animation Module

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing any creature except the one with Tarrian's Soulcleaver attached, adding CC.
2. When the creature dies, Tarrian's Soulcleaver triggers, putting a +1/+1 counter on the creature it is attached to.
3. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
4. Repeat.

This looping engine turns a simple sacrifice outlet into an infinite-value machine by exploiting a clever exchange between counters and tokens. You sacrifice an expendable creature to Ashnod's Altar for two colorless mana, which then fuels the entire cycle. That death immediately triggers Tarrian's Soulcleaver to drop a +1/+1 counter onto your equipped creature, which in turn wakes up Animation Module's triggered ability. By paying just one of the mana you generated, the Module pumps out a fresh Servo artifact creature token to take the place of the fallen, leaving you with extra mana and an ever-growing threat.
