Animation Module + Intruder Alarm + Master Biomancer

Animation Module

Intruder Alarm

Master Biomancer

How it works

1. Cause a creature to enter the battlefield, which enters with at least two +1/+1 counters on it due to Master Biomancer.
2. Intruder Alarm and Animation Module trigger.
3. Resolve the Intruder Alarm trigger, untapping all creatures.
4. Holding priority, activate a mana-producing creature by tapping it, adding at least 1.
5. Resolve the Animation Module trigger, causing you to create a 1/1 Servo artifact creature token that enters the battlefield with at least two +1/+1 counters on it due to Master Biomancer.
6. Repeat from step 2.
