Newbie and Discard

Hello all! So, I used to play magic (was going to qualifiers, etc) but due to life and everything else I have sold my collection twice. I did keep a few decks to play causally but I am not sure what for at the would even be at this point.

Anyway, I am hoping my local shop is going to start running pauper events soon (that's the rumor) and I figured I could build a few decks that won't break the ye old wallet.

I have built a aggro red deck that looks like it is going to be a blast.

But I think it would be awesome to build a mono black discard with a touch of aggro. I have looked at some deck lists and none of them stood out to me.

Any suggestions?
