Restoration Angel would be the only thing I'd heavily consider and maybe Obzedat, Ghost Council in side vs control/midrange.

Oh and +3-4 Cavern of Souls

Check out my Blood Artist extortion deck for some possible inspiration. Con Artist

What would you take out of the sideboard for Obzedat, Ghost Council or Restoration Angel ? Every card has a very specific purpose, and I think the angels are just win-more most of the time.

I played B/W Zombies for about a month or so and all but once went 4-1 or clean sweep. Restoration Angel is a great flyer to choke back on for more Geralf's Messenger or saving a Blood Artist in addition to a 3/4 flash flyer. Saved me tons vs a Hellrider as well. And with your version you can hit Disciple of Bolas again and refill your hand. Skirsdag High Priest is a fun card but IF Restoration Angel took it's place then that'd cover your flyers, as well as it's just a fluff card or more win (personal opinion, I play Aristocrats using them as well). And for Obzedat, Ghost Council I'd probably take out Lingering Souls , another great card but angel is better (and double Obzedat proc with Resto angel as well).

If you don't like Restoration Angel at all you could just run Orzhov Charm to throw back a Messenger or Disciple back to hand to recast again.

My only concern is that adding more white cards to the main board is tough with only 8 white sources. If I add basic plains, those are lands which don't allow me to cast Geralf's Messenger . Thoughts? I suppose Restoration Angel 's 4 mana cost makes it more likely to get my white source in time.

Cavern of Souls and Orzhov Guildgate fix that actually.

Cavern and Angels makes my deck $150 more expensive :(

And what I really like about the demon tokens is they survive a Mutilate while an angel doesn't.

Well only when you're at 4 swamps. Caverns could potentially throw that off. Desecration Demon would be around the same rout for a Mutilate surviving demon, as well as artist procs. Usually board wipes in zombies I enjoy running Killing Wave to save things I still want/need.

The purpose of mutilate in SB is for aggro decks, and they usually have enough life to be able to keep their big guys, but I'll test it out.

Why not Obzedat, Ghost Council ?

Well, the card goes counter to the deck archetype. Obzedat, Ghost Council is a slow, relentless whittling away, whereas my deck wants to win within 5-6 turns. Casting Obzedat, Ghost Council on turn 5 doesn't help me out at all in that way.

Your "combo" seems like a "magic dream" to me, but hey if you get to pull it off more power to ya (I'm talking about Geralf's Messenger combo with 3 other creatures on the field).

You COULD also run a SB card of Immortal Servitude to be good against Esper or other control decks that use Supreme Verdict or milling tactics

I cannot touch this deck and it pains me to admit it. Every single time I play against it I want to scream. That said, it has my upvote.

Food (wink) for thought, War Priest of Thune vs Erase , yes Erase is instant speed and exiles but Priest is creature fodder for Artist/Vamp/Bolas.

A single copy of Griselbrand may be the nail in the coffin for some matchups. Also with such a creature heavy deck you'll want Cavern of Souls vs control decks. But its got my upvote. Could ya check my deck out? liliana for the win

dude if i ever face you i will surrender asap and cry. with that said +1 from me.

Cool! I like the originality of your deck XD

Have you considered Thalia, Guardian of Thraben ?

What would you cut for Thalia, Guardian of Thraben ? My 2 cmc slot is already pretty fairly represented with valuable creatures I'd almost always have over Thalia.

I like this deck and I think Sin Collector might be something to consider for the sideboard.
