Isn't 6 black sources a bit low for the {B}{B} of the rats?
Statistically you'll be drawing 20 cards to get to that.

Yeah you're right. I'm still working on the mana base.

I think you'd be better off using swamps and some red/black duals.  Ramp with {dark ritual}, {culling of the weak} and {crypt ghast} or don't ramp at all.

{bubbling muck} could do the trick, or {Urborg, tomb of yawghmoth} + {Cabal Coffers}.

Just cut the {Impact Tremors} and maybe 5 rats, go mono black and add {Mogis' Marauder} / {Grey Merchant of Asphodel}. More efficient that way.
