We've had several boards in a row where we dealt out beggar and scoffed because who would want to buy beggar unless there's Counting House or Gardens or something? Anyway, I've decided it's pretty good for a 3-provinces 6-duchy strategy, much like the ancient "bureaucrat beats chapel" strategy. I bought it in the middle of a game where my opponent was maraudering me a bunch (I also twice used a band of misfits as a beggar) and I didn't expect to shuffle too many more times, and was happy. I only think I used the reaction once or twice; the immediate +3 was the big help.
