I think this card becomes a straight upgrade to St. Hubert's Key in 1-2 gator teams. And I think pretty highly of Hubert, so that's saying something. This takes Jim, Mateo, and Akachi to new levels, and Agnes won't complain about being able to save Shrivels with a Baseball Bat, Fire Axe, or Knife.
It is much less good at higher player counts. 4 gators means 4x as many checks, and losing the (+1) token can be a real drag on your team when they have to take a treachery on the chin.
Conversely, this is a bomb solo card and will probably go into every solo mystic I play until the end of time. Oh, and Lola likes this one too.
I love this card and its ability to make well-rounded investigators quite powerful.
