Our local meta recently had a Hand of the King tournament. I came in second using a Night's Watch build out of Stark, my only loss being to the winner who was using a GJ winter choke deck. I wrote up a little analysis of how the format differs from regular Joust, specifically with regards to the deckbuilding process around the Hand. Check it out here, it might help if you have an upcoming tournament or you just want to try out the format.
