I have a casual Mask build, so my initial suggestion was going to be Fabricate. Not as necessary for you though. Also, think about running something in addition to Dreadnoughts; I also run Hunted Horror and Eater of Days. Even like 1 each, just so you still have a potential wincon if the Noughts get hated out somehow. Let me know if you'd like to see my list.
If you decide to go black, I would suggest Parallax Nexus and Suppress with Nexus being the faster card, so a better choice. (Still, if you want coolness points you can play Suppress and when it works do what Urza is doing in the picture while going MUHAHAHAHAHAHA)
The Parallax cards work with Stifle/Trickbind by countering their leaves the battlefield triggered ability thus permanently removing lands/cards.
If you want to abuse these enchantments you can also consider a UWB build with Opalescence. With Opalescence in play you can use Parallax Wave to remove itself from the game or any of the other parallax cards. Toss an Enchanted Evening in that mix and you can exile any and all of the opponent's permanents. If you try that, I would also suggest Seal of Cleansing and Oblivion Ring.
Still, I think the mono-blue control build is the best. Remember, you can always play aggressively by stifling fetchlands and wastelands and then slamming down a Parallax Tide or using Jace as pre-emptive mana denial by reducing the opponent's chance of drawing land/mana until you activate his ultimate or successfully land a nought.
