I like the idea, but .... Forget Emrakul, the Promised End. With this deck you will seldom survive long enough to summon it. I would concentrate more on lowering the mana curve and loading the graveyard with creatures that you can reanimate.

Although I did build a Relentless Dead deck at some stage, I must admit that I haven't played it too much. Most other players of similar decks tend to focus on Kalitas, Traitor of Ghet. I no longer have any copies of Kalitas in my own collection, but quickly put together mz (minus 1 Liliana), which seems to address some apparent weaknesses in your deck.

Make that Murphy Z, I did not expect that name clash...

Yeah probably you have right about Emrakul, the Promised End. In fact in these days I was thinking to remove it. I think to put or another Diregraf Colossus or Noosegraf Mob... for you which is the best?

Also if you have more suggest i'd be pleased to hear it!

You have a bit of white mana, Anguished Unmaking is a great removal spell. Haunted Dead and Prized Amalgam would also be good additions. Markov Dreadknight and Rancid Rats feel a bit out of place and not that great. Noosegraf Mob is a bit slow. Add another Diregraf Colossus. I also think you need more discard outlets for all the madness triggers.

Thank you! So I think to remove some cards:

-2 Markov Dreadknight

-2 Rancid Rats

-1 Noosegraf Mob

-2 Cemetery Recruitment

-3 Swamp

Now I put:

+2 Haunted Dead

+2 Prized Amalgam

+1 Diregraf Colossus

+2 Anguished Unmaking

+3 Plains

What do you think?

If you have them Smuggler's Copter makes a great discard out let for your maddness and a 3/3 flyer.

Yeah that's vehicle is excellent, but I don't like too much vehicles... in any ccase thanks for the suggestion! If you have some more ideas I'll be pleased to hear it!
