This seemed like an interesting combination to me. It's sort of a ruggedized James Bond. :'] Favored Enemy + Art of Deception seems nifty, as does Sneak Attack + Ranger's stealthiness.
Another interpretation might be bounty hunter -- no matter where they go, no matter where they hide, in the wild or in the city, such a guy can hunt them down.
The saves dovetail too, which I dig.
