How it works
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.
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.
Resolve the Xavier Sal ability, causing you to populate.
Activate Viscera Seer by sacrificing the additional Human, Fungus and/or Pirate.
When the creature dies, its undying ability triggers, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
When the creature enters the battlefield, Intruder Alarm triggers, untapping all creatures.
Resolve the Viscera Seer ability, causing you to scry 1.
