Captain America, Team Leader + Animation Module + Phyrexian Altar + Conspiracy

Captain America, Team Leader

Animation Module

Phyrexian Altar

Conspiracy

How it works

1. Put a +1/+1 counter on a creature you control.
2. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
3. When the Servo enters as a Hero due to Conspiracy, Captain America triggers, putting a +1/+1 counter on it and the Servo.
4. Animation Module triggers twice.
5. Holding priority, activate Phyrexian Altar by sacrificing the Servo, adding 1.
6. Resolve the first Animation Module trigger, choosing not to pay.
7. Resolve the second Animation Module trigger, causing you to pay 1 to create a 1/1 Servo artifact creature token.
8. Repeat from step 3.

This ingenious loop transforms simple counter placement into an endless mechanical assembly line, beautifully orchestrated by Conspiracy redefining every creature you own as a Hero. Because of this type-shifting, every time Animation Module helps birth a Servo token, Captain America, Team Leader immediately steps in to hand out a +1/+1 counter to both the newborn Servo and himself. That influx of counters triggers Animation Module all over again, fueling a surplus of triggers that lets you sacrifice the Servo to Phyrexian Altar for the exact mana needed to keep paying for the next iteration.
