Looking for NM black staple cards and black alpha cards

Along the lines of:

Necropotence
Yawgmoth's Will
Yawgmoth's Bargain
Phyrexian Arena
Juzám Djinn
Vampiric Tutor
etc.

Anything that really represents the colour black, including historic cards. Only looking for the earliest print of a card (non-white border). Also collecting NM black alpha cards.

I have a bunch of stuff on my tradelist, so don't be afraid to make an offer.
