The mana curve is too steep, the deck looks like an unfocused, inconsistent mess. If you take a look at the vampire deck on my page, it should give you an idea of a vampire deck that works. But there are other ways to build them, such as a sacrifice/burn engine or using alternative color splashes like Black/Red or even Black/Green. Vampires are meant to be aggressive, enjoying low mana curves and a lot of lords and killspells. They want speed and swarming.

Actually ive won almost every game with this deck! It works pretty fast and ny endgame card is only four mana. Its pretty consistent once i get Nocturnus, Sorin and Bloodhost out! I just need to figure out those four cards i mentioned in the description. I dont want to splash red or green, i actually have enjoyed splashing white just for Sorin. I also have acess to exactly zero cards right now beyond the ones me mentioned and this deck was made with all cards i already had! Thanks for your input tho
