As expected: joust could work in ctrl warrior or handlock, but I'm not sure that you would want any of them in those decks anyway. The main contender is probably heal bot jouster in handlock, but you are probably better off taking the guaranteed +8 on the smaller body than gambling on the +2/+2 in most matchups. However, there is an argument that it would be more likely to work vs aggro which is where you need it anyway.
However, I can also see a midrange paladin jouster deck working. Between the "chow" jouster and the joust weapon you probably have enough board control in the early game to allow you to run more powerful jousters further up the curve.
