I run a zombie tribal deck (Lord of Tresserhorn, and you can find the primer in my signature. Although my deck has red in it, you will find a lot of the same cards you could expect to find in a blue/black version.

I'd use cards like Living Death, Patriarch's Bidding, Volrath's Stronghold, Unholy Grotto, and Havengul Lich.
