Dual lands might be nice to have in this deck.

If you can't get ahold of any dual lands such as Drowned Catacomb , Darkslick Shores , there is always Jwar Isle Refuge which is cheaper.

If you can't get either of those, I suggest you run more swamps than islands since you need more swamps. Also, 4x Rooftop Storm is too much, and all of your zombies are relatively cheep. I would drop those. Grave Titan is a great card because it can get damage in as well as put more zombies out there. Also, consider Stitched Drake it's a a cheap card and it gives evasion. Chances are, you'll have a creature in the graveyard at some point. Also, without Undead Alchemist you really won't be able to mill their entire deck. Consider more mill options, or dropping it completely.

Lich Lord of Unx !

Also, Mind Funeral .

Bitter Ordeal + Tome Scour

i would have to say Mindcrank because of the potential damage being turned into cards and not only that but if your doing multi game than u can watch your friends do half the work for you trust me i have 3 in my mill deck and its wonderful to stack up on. if you decide to try Mindcrank you should put Grave Titan in there to help make the numbers biggerDROP Agony Warp Mind Rot Stitched Drake and Festering Goblin for my add of 3x Mindcrank and your 4x Grave Titan

good luck with it dude like the idea of undead milling

I dont like the Mind Rot so much, i would go with something like more mill or Syphon Mind or Syphon Flesh to give you something since thins is about mill not discard. Also slip in a Jace if you can and maybe a counter or two for good measure. Also, I really hope you named the deck after the movie, and I plan to do the same with a zombie deck i just made going in the same direction.

Needs more soulless Ones! Also add Behind the Scenes + Grotesque Mutation for fun.

Gravecrawlers are extremely good because of their recurrsion and threat value they are 2/1 for b the only downside is they can not block
