The First Peoples like sidekicks, and they like spirits.
in the ideal world for the Vengeful pack, you only have one casualty to absorb (tie or one rank loss) - cast this during resolutions, use the Sidekick to Take the Lumps, and now you have a Gunslinger to help swing round two in your favor (or the Gunslinger soaks another two hits).
That extra 2 stud might chase the other player away. As well they should run away from a Vengeful Pack.
