Take out Interloper, Child of Night. Add Blood Artist and more kill cards. Falkenrath Aristocrat is a better option for that sort of mana base. This is what I have now: deck:this-is-it-dont-get-scared-now
i think i'm going for the more aggresive option, hence the interloper and child. I've found blood artists are much less effective than a 2/1 with a relative ability.
If you are going for a more aggressive option, take out Olivia. Falkenrath Aristocrat is much more aggressive. She can protect herself, too!
thats a very good point but i've found olivia has been good do i'll cut 1 for now. But first i have to get my hands on one.
i would consider 2x Bloodline Keeper Flip in the sideboard to side in for Nocturnous verse control decks because it gives them an advantage of knowing the card you will draw. Also since most of your creatures already have flying the solid 2/2 from flipped bloodline could be better, i personally like keeper better than nocturnous, but i do still run 2x Nocturn's in my deck. Also i would consider putting in at least 2xSign in Blood the extra draw in an aggro deck is very useful. and the two life can easily be offset by many of your creatures. as far as sideboard goes some of the suggestions are not black, but still are nice, for example card:Tormod's Crypt is amazing against frites/snapcaster decks, and also Combust is a great card vs. blue/any restoration angel deck/white. Bonfire of the Damned is in my opinion the best board wipe in the game that should go in vs aggro decks. I apologize for the lengthy comment, but thought i'd give my input. I will be using a mostly black but using red for burn spells midrange vampire deck myself, +1 for the list though looks decent, just needs a solid sideboard.
i think i may have the option to become a slower deck post sideboard like how delver does with timely and sphinx.
oh also if you have access i would def put in Cavern of Souls
oh yeah totally forgot i have two try to get my hands on 2 more
I prefer card:Grafdigger's Cage over card:Tormod's Crypt for sideboard.
You're gonna need some artifact hate in your sideboard. Since you have plenty of red sources I would suggest some Smelt s. You are not going to need those 2 land in your sideboard. If anything your nocturnus has a greater chance to get stuck as a 3/3 with more land. Also, since you don't have any red spells except for the creatures, I would get rid of the 2 mountains. You already have 6 red sources so getting out a captain or olivia shouldn't be too much of a problem, but that is for you to decide. I've been playing a deck very similar to this for a while and it has been doing quite well. Check it out, let me know if it helps a little, and feel free to ask questions/give suggestions for it. deck:black-blood-suckers
