I'd swap one Doom Blade with a Go for the Throat . after sideboarding, you can make the switch depending on wether your opponent is playing robots or not.

i'm surprised at what little you have in terms of ramp... might want to run Birds of Paradise alongside Deathrite Shaman running both would allow you to cast your lilianas and cliques by the second turn.

I'm not sure if the spoiler was a fake, but i think the dimir uncounterable spell costs UB and says counter target spell unless it's controller pays 10 life. though with a heavy colour requirement i'm not sure it's something worth considering...

+1 btw. I'm not a big fan of Jund either
