The 4 combo pieces

What must be in place

You control at least one creature with one or more +1/+1 counters on it.
You control at least one other creature.
Morselhoarder has exactly one or two -1/-1 counters on it.
Thornbite Staff attached to Xavier Sal.
Xavier Sal does not have summoning sickness.

How to execute it

  1. Activate Xavier Sal's second ability by tapping it and sacrificing a creature.
  2. When the creature dies, Xavier Sal triggers, untapping Xavier Sal.
  3. Resolve the Xavier Sal ability from step 1, putting a +1/+1 counter on a creature you control and a -1/-1 counter on Morselhoarder
  4. Animation Module triggers, holding priority, activate Morselhoarder by removing a -1/-1 counter from it, adding {1}.
  5. Resolve the Animation Module trigger, causing you to pay {1} to create a 1/1 Servo artifact creature token.
  6. Repeat.
  7. Once you have infinite +1/+1 counters among creatures you control, you may instead use Xavier Sal's first ability to get infinite copies of creature tokens you control.
