Sams upgrade is pretty bad, so I'd agree to that needing a fix.
Giving Sam some form of defense would be nice, he is really fragile.
The Exorcist, as have been said, needs a little something, though I dont really know what.
Wastrels....does anyone even use them? Maybe give them Manipulative 11 or something?
When I take Santiago, my opponents usually ignore him, so he doesn't become really dangerous, but I think his card is fine.
