I'm curious to see how this deck is developing for the rest of you that have been playtesting it and making changes to it.  I posted my last couple changes, and that's what I'm still running now.  Liam... you're still trying things out, right?  Come up with anything?

The problem your deck has against Grimlong and Pitchlong is that theyre just faster. Your deck relys on bob for card advantage and mini tendrils, needing a few turns to set up. How many duress effects do you have maindeck? Duress isnt a guaranteed win, but it sure helps remove disruption or bombs out of your opponents hand. What is your sideboard looking like right now?

@ Doomsday

The direction you would need to take to play Doomsday would require you to play more Sensei's Divining Tops ala Legacy Tendrils. That, combined with a singleton draw4 lets you build a pile like this (assuming you have a Top in play):

[Top]
Cruel Bargain/Infernal Contract/Meditate
Black Lotus
Lion's Eye Diamond
Lotus Petal/Mana Crypt/Random Mox
Tendrils
[Bottom]

This will add 6 storm + Tendrils for a total of BBBBBB (or 2UBBB) and has the potential to use extra Sensei's Tops in the 0cc Artifact Mana Slot to generate extra storm for an additional 2 colorless. There are probably better individual piles to use in specific situations, but a general pile could look something like that. I don't necessarily think that the deck as a whole would benefit from including 4 Sensei's Tops to try to fuel a 1-of Doomsday like this (although, admittedly, you could use pass the turn Doomsday stacks and still combo the card with Ancestral Recall, Ponder, and Brainstorm) but you might be able to force the issue in this deck or a similar deck with at least some success.
