Here's my version. Passive Aggressive. You need a sac outlet for free. Demonmail Hauberk is usually a game ender when 2 zombies including Gravecrawler and Blood Artist are out. Falkenrath Noble would also fit in nicely.

I'll give Demonmail Hauberk a try. Thanks!

Killing Wave isnt really good because it gives the opponent the choice...if hes wiinning hede easily pay life, if not some lands or creatures...technically you waste an entire turn/mana on an opponent and they still have the upper hand..

for board sweep probs use Black Sun's Zenith its very efficient. not bad though

When I look at Killing Wave to me it is usefull if you play it for about 3->6 mana make the choice hard for them. you also need more direct damage spells to make it worth it in your deck. Black Sun's Zenith is pure creature control which would work better in this deck seeing as that seems to be the theme with the other spells.

I use Killing Wave on myself for a cost of one swamp to wipe my creatures out while Blood Artist is out,then they all come back.

Try adding sone Mountain and a few Diabolic Tutor and 2 or 3 Defiler of Souls that would help the sac aspect of it

or if you don't want to add mountain add 2 Eldrazi Monument that would make your creatures indestructable and you have to sac one each turn to keep it on the field

Added a few Black Sun's Zenith. Does it remove the +1 +1 on my undying creatures?

Hammer, neither Defiler of Souls nor Eldrazi Monument are standard.

This deck seems like it's becoming divided with it's self. On one hand you have things that can work fantastically well like the Blood Artist, Gravecrawler and Demonmail Hauberk sac combo. Then you have Undying effects that mix -1/-1 counters on creatures to maintain an upper hand, but then there's Black Sun's Zenith to take out your Blood Artist? I know you can slap an Undying Evil on him but you won't always have that. I feel like it will end up with either blood artist gone and more counter manipulation for undying effects, or blood artist stays and undying creatures are a tool used to gain the upper hand. Personally I was a fan of the Zombie Apocalypse, and Killing Wave version. Also, Where's the 4x Altar's Reap? it's perfect for this deck.

I wasn't so sure about Black Sun's Zenith. I'll throw Killing Wave back in. Altar's Reap is awesome! It's very similar to Scarscale Ritual. Thanks for the advise!

Demonic Taskmaster would love it here

Just noticed that Black Cat in your maybe board. Try that out instead of the Fume Spitter and see how it goes. I think it would help get Gravecrawler back onto the field if need be.

That's what i was thinking. The "discard a card at random" effect on the Black Cat can be really powerful.

great deck

I agree on Black Cat for Fume Spitter

This is a pretty sweet deck +1. Check out my Massacre's Harvest

phyrexian obliterator

ever thought about Bloodthrone Vampire ?

Bloodthrone Vampire would be nice but i need zombie synergy for Gravecrawler and fuel for Mortarpod .

Thank you sir. I just ran this at FNM and it finally broke my 2-3 streak. I went 3-2. Thank you.

That's great! I went 3-0 tonight too! I was staring at a Shrine of Burning Rage with 12 counters on it lol it was scary,manage to Mortarpod my Highborn Ghoul for the final blow.

Does Mortarpod make this deck that much better? My two losses were to Mirran Crusader. That card rolled right over me, especially when a sword or angelic destiny made it's way onto him. I forgot to sideboard in some proc or hexproof killers. Barter in blood would have worked too. I absolutely love this deck though. It's fun, and it's almost like your opponent can do nothing against the damage he takes, because it's sac damage. What do you do against swords or enchantments?

I use Distress for enchantments and artifacts but that's it. It's this decks biggest weakness.

@CptMalReynolds

You can throw some Despise in to discard their Mirran Crusader
