Tidus, Blitzball Star + Animation Module + Phyrexian Altar

Tidus, Blitzball Star

Animation Module

Phyrexian Altar

How it works

1. Cause an artifact to enter the battlefield under your control.
2. Tidus triggers, either putting a +1/+1 counter on it.
3. Animation Module triggers. Holding priority, activate Phyrexian Altar by sacrificing another creature, adding 1.
4. Resolve the Animation Module trigger, causing you to pay 1 to create a 1/1 Servo artifact creature token.
5. Repeat from step 2.
