Want to do mono black, but I can't think of many cards to put in.
{Crypt Ghast} {Griselbrand} {Liliana of the Veil} {Sever the Bloodline} {Doom Blade} {Mutilate} {Sign in Blood}. Just kinda a list of really good black control cards, friend runs a mono-black deck and uses crypt ghast to get griselbrand on turn 5. The decks alot of fun and with doom blade back it's alot better. Ill look into more m14 cards and figure out some more cards for ya.
{Lifebane Zombie} {Diabolic Tutor} {Duress} {Appetite for Brains}
{Mutilate} and {Vampire Nighthawk}
