MTG Salvation

My Dralnu is a combo version >:D. (Doomsday - Lab Maniac)
What do you mean with multiple casts of Exsanguinate? Unless you copy it, you can only play it twice?

Propaganda is better than Night of Souls' Betrayal.
If you're looking for other effects: No Mercy, Crawlspace should help you out as well.

Reason that Necromancy is fun is a blue creature called Kederekt Leviathan :cthulhu:.
A great way to dump some creatures in your graveyard is Buried Alive, which is an auto-include in a lot of reanimation strategies.

I was wondering why you didn't include that, since you have a Cryptic Command in here :P.

For the mana base you could add Polluted Delta and Creeping Tar Pit.
They're pricey but a good mana investment is always worth it.
If you wanna add more reanimation Necromancy is another good card.
Wayfarer's Bauble for more mana ramp, also you can't go wrong with a Solemn Simulacrum.

What's your experience with Army of the Damned and Freed from the Real?
Thousand-Year Elixir is better if you're looking for that effect.

What about Vampiric or Demonic Tutor over Diabolic Tutor? =)

Instead of Zombify why not Rise from the Grave?
