Fox might be replaced by any of the following words, for the lack of an accurate translation to the Hebrew word "×§×•×ž×‘×™× ×˜×•×¨":
Trickster, Snake, Weasel, Conniving, Smooth-talker, Sweet-talker... It should be a POSITIVE word signifying someone slick who gets around, gets what he wants by knowing the right people, and pushing the right buttons.
