How it works

  1. Activate Xavier Sal's first ability by tapping it and removing a +1/+1 counter from the additional nontoken Human, Fungus and/or Pirate if it has one, or any counter from another permanent you control otherwise.
  2. Xavier Sal triggers, causing it and all other creatures you control that share a creature type with it to get +2/+0 and gain undying until end of turn.
  3. Resolve the Xavier Sal ability, causing you to populate.
  4. Activate Spawning Pit by sacrificing the additional Human, Fungus and/or Pirate.
  5. When the creature dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
  6. When the creature enters the battlefield, Intruder Alarm triggers, untapping all creatures.
  7. Resolve the Spawning Pit ability
  8. Repeat.

This intricate loop hinges on leveraging **Intruder Alarm** to turn every creature death and entry into a cascading untap fest. By sacrificing a creature to **Spawning Pit**, you trigger **Haunted One** (granting your commander undying) so it immediately returns with a +1/+1 counter. That new entry wakes up the entire board via **Intruder Alarm**, including **Xavier Sal, Infested Captain**, who can then strip that very counter away to populate your token army while keeping the loop going.
