How does this deck do?  6 mountains seems like a tad bit too much IMO.

Does pretty well in my short bit of play testing.  However, when I test I use despise instead of dread bore cuz I'm too lazy to make a card on MWS.  And the land seems pretty good, I always seem to have some way of casting a Stromkirk Noble turn 1

Wow

I have been HEAVILY debating whether to run {Sign in Blood} or the new {Phyrexian Arena} Enchantment, I've been slowly making my B/R Vamps post rotation viable.

EDIT: That's because I'm supposes to run both...
