Μετάφραση - Αγγλικά-Χίντι - Let's toast to that, you fox

Fox might be replaced by any of the following words, for the lack of an accurate translation to the Hebrew word "קומבינטור":

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.
