Yummy, I love me a good black deck <3
For one, it does look pretty good! Just what I like to see.
Urborg, Tomb of Yawgmoth Can probably go, as everything aside from like 5 land are swamps anyway. Same goes for Infernal Darkness . Don't get fooled into thinking you get double mana for each of these!
card:Akroma's Memorial. You can't cast any spells are attach anything to your black creatures with this out.
I'd replace the cards mentioned with card:Geralf's Messenger, Gravecrawler , Ring of Xathrid , Elbrus, the Binding Blade Flip , Seizan, Perverter of Truth , Rune-Scarred Demon , Sheoldred, Whispering One .
Overall, I really enjoyed this deck! Keep it up!
I like all of your suggestions except one urborg stays in so it can turn all of my opponents lands into swamps for the swamp walk ability of zombie master.
Ohhh, my bad. Didn't see that. Yup, works just fine :D
Infernal Darkness also makes all of your opponents lands produce only black mana as well. From experience, anyone playing anything but black in a multiplayer game is screwed when that resolves for a few turns. I suggest leaving it in.
Another nasty way of locking down your opponents is Mana Web and urborg. Anytime they tap a land, they tap em all.
Looks fun to play :D
Thank you everybody for the suggestions everybody once i get done with this medical training in japan ill be back and be able to start experimenting.
