Vampire Burn

i have built and run this deck for the past few weeks. it handles jund, red win, bushwacker, naya, and vamps on a regular basis with the real challenge being white or white green allies that have the exile instances and devout light caster, feed back please, please only leave feed back, dont just bash it if you dont like it unless you want to give ideas, red helps remove the abyssal and gives edge in mirror match in my experiance one mountain might seem weird but about 1 of ever 5.5 cards is or pulls red mana and 1 of every 3.2 pulls or gives black mana thank you will be trying to get 1 more nocturnus
