Interesting set, but what if they use something like SR first turn as you Dbond then just 2KO you? I guess you can try MC/Countering them, but in that situation the best it ends for you is they get SR up and lose their lead while Wyn takes significant damage (maybe enough to make it not useful for the rest of the match). It seems like it's got some very nice surprise value, and could be fun for setting up a Drummer or something, but a good player should be able to beat it or stop it doing too much harm without much difficulty.
As well as having problems with Taunt, sleep moves and people who SR first turn then attack (especially with mixed leads) it will not appreciate Trick. Still it could be a great lead sometimes against people who are not expecting it, especially if it's moved out of Ubers where Wobb lives.
