Animation Module + War Elemental + Ashnod's Altar + Pandemonium

Animation Module

War Elemental

Ashnod's Altar

Pandemonium

How it works

1. Cause a creature to enter the battlefield under your control.
2. Pandemonium triggers, dealing damage to an opponent equal to the creature's power.
3. War Elemental's second ability triggers, putting a +1/+1 counter on itself.
4. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
5. When the Servo enters the battlefield, Pandemonium triggers.
6. Holding priority, activate Ashnod's Altar by sacrificing the Servo, adding CC.
7. Resolve the Pandemonium trigger, dealing 1 damage to an opponent.
8. Repeat from step 3.

This clever loop turns the explosive entry of any creature into an unstoppable engine of growth and sacrifice. With Pandemonium fueling War Elemental's rage by turning every entry and subsequent Servo strike into player damage, Animation Module easily converts those incoming +1/+1 counters into a steady stream of artifact tokens. Ashnod's Altar then provides the necessary mana to sustain Animation Module's trigger, ensuring you can repeat the entire cycle infinitely to crush your opponents.
