OK at some point you have to actually give some constructive criticism... I just lost respect for some of you, I could tolerate it up to this point but COME ON you don't HAVE to comment on it. Just please, at least for my sake... actually help?
Comments now.
This deck type (Mono dark) has been suggested before, and I don't think it fits, plus you have very little focus, the fact its all dark is really the only thing tying it together. I would remove the nightmares and most, if not all, of the cloaks. Now chances for creatures are much greater.
