Xavier Sal, Infested Captain

Haunted One

Thornbite Staff

Blasting Station

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. If you created a creature token, Blasting Station triggers when the token enters the battlefield, untapping Blasting Station.
5. Activate Blasting Station by tapping it and sacrificing the additional Human, Fungus and/or Pirate.
6. When the creature dies, its undying ability and Xavier Sal trigger.
7. Resolve the creature's undying trigger, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
8. When the creature enters the battlefield, Blasting Station triggers, untapping Blasting Station.
9. Resolve the Xavier Sal trigger, untapping it.
10. Resolve the Blasting Station ability, dealing 1 damage to any target.
11. Repeat.
