So yeah im semi new to edh and magic only been playing for about 4 months.

Would like help.

My commander is sheoldred, whispering one.

I didn't see anything on your tradelist that was a "mono black staple" what exactly are you looking for?

I'm guessing you mean stuff such as:

-Cabal Coffers
-Magus of the coffers
-Damnation
-Grave Pact
-Necropotence
-Urborg, Tomb of Yawgmoth
-Demonic Tutor
-Vampiric Tutor

Are these the cards you'd be looking for if so maybe we can work something out?
