Mono Blue control's really not that great of an option right now. Type 1 Mono-U has always existed to abuse a single card: Back to Basics. Sadly, right now even combo's running a ton of fetches and basics. And lots of fetches and basics makes Back to Basics cry.
Your best bet is just to retool the deck into Control Slaver or Gifts. You keep much of the same control elements, and a solid mana base, but gain a much better win condition. Will's a pretty good card as well.
If you really insist on Mono-U though, you're going to need some form of board clearer. I guess that's basically Powder Keg. You might also want to add Tinker+Colossus as aggro can pretty much just run you over. Granted, you'll still have trouble with Friggorid, but there's really not much else you can do without going into additional colors.
If B2B is ineffective because everyone has fetchlands, would splashing red for Blood Moon be better? Not mono-blue, but still serves the same purpose. The metagame seems right for it, I mean everywhere you look its either bazaars or as you said, fetchlands. I could be completely wrong though, I'm just throwing out some thoughts. Although, if you are already going red, why not slaver?
As for the win, I like Meloku and tinker + colossus.
