I wanted a deck that plays full power (Im really not counting Twister as power any more.. Library or Time Vault has taken its place), is really quick and stable. The deck also should have few bad draws. The obvious choice for me is a deck with lots of cheap cantrips and a cheap "combo" to go off quick. Blue and black combined gets all the defensive spells needed against opposing combo decks and also has the cantrips.
Night's Whisper is a card I really hadnt thought a lot about before it won a tournament a month or so ago but it does almost everything you want. At two mana it is a bit harder to counter and since you draw two cards it cant be misdirected. (I think Misdirection is one of the best cards in the whole format)
The 3 Jace are there just as a backup plan and some times you just autowin having a first turn Jace. It is also a wee bit easier to cast then Doomsday.
Doomsday.. yea you lose lots of life.. but you play it as a tutor for the next 4-5 turns. Once cast you should have your whole gameplan there. Drawing Shelldock Isle hides a creature away and the rest of the stack should be defensive spells and or card draws depending on what your opponent is playing. Yes a Wasteland + removal is death but that is something you should be able to handle with all the reactive spells and discard.
The mana base is a land or two more then the other combo decks but the gameplan of casting a BBB-spell kind of forces you to have access to black mana. I opted to not play Dark Ritual and tendrils for their "looseness". Stability is the way to go imo.
Mana Leak could be Duress or Spell Pierce but I wanted a cmc2 counter and felt Leak is best with that many colorless sources.
You can play this deck powerless too. Playing more lands and Dark Rituals replaces the lotus/moxen. YawgWill/Ancestral/Thirst/Tinker becomes Preordains. Blightsteel -> Emrakul. Library becomes whatever you feel could be good.
