The 3 combo pieces

What must be in place

You control at least one creature that has a +1/+1 counter on it.
You control at least one creature that can tap to produce at least {1}.
You control at least one additional creature.
Xavier Sal does not have summoning sickness.

How to execute it

  1. Activate a mana-producing creature by tapping it, adding at least {1}.
  2. Activate Xavier Sal's second ability by tapping it and sacrificing another creature, causing you to put a +1/+1 counter on a creature you control.
  3. Animation Module triggers, causing you to pay {1} to create a 1/1 Servo artifact creature token.
  4. When the Servo enters the battlefield, Intruder Alarm triggers, untapping all creatures.
  5. Repeat.
  6. Once you have infinite +1/+1 counters on a creature, you may instead use Xavier Sal's first ability to get infinite copies of creature tokens you control.
