If you were interested in combos, anything with persist goes horribly infinite with Mikaeus, for example Wingrattle Scarecrow with a sac mechanic like Phyrexian Altar /Ashnod's Altar /Altar of Dementia . Cauldron of Souls might be a good piece.

Something I enjoy doing in mono black during lategame is Rain of Filth into Exsanguinate lol even better if youve got Cabal Coffers /Bubbling Muck .

I cant say that Ive had much experience with zombies but ive had a bit with tribal so Coat of Arms , Door of Destinies , Eldrazi Monument are often good additions. You could probably afford to get rid of some of your worse artifacts and put some more zombie in (is Phylactery Lich really worth it?).

It's typically best to avoid weenie creature cards in EDH because they don't really represent an efficient and effective utilization of resources.

Cards I would cut:

• Abattoir Ghoul - Seems ineffective.
• Accursed Centaur - Inefficient and ineffective.
• Black Cat - Inefficient and ineffective.
• Butcher Ghoul - Inefficient and ineffective.
• Corpse Blockade - Inefficient and ineffective.
• Creepy Doll - Inefficient and ineffective.
• Dead Reveler - Inefficient and ineffective.
• Diregraf Ghoul - Ineffective.
• Gutter Skulk - Ineffective.
• Highborn Ghoul - Ineffective.
• Hunted Ghoul - Ineffective.
• Rotlung Reanimator - Seems ineffective.
• Severed Legion - Inefficient and ineffective.
• Sewer Shambler - Ineffective.
• Sightless Ghoul - Ineffective.
• Stuffy Doll - Seems ineffective.
• Terrus Wurm - Seems ineffective.
• Walking Corpse - Ineffective.
• Wight of Precinct Six - Conditionally decent.
• Conjurer's Closet - Unnecessary.
• Warden of the Wall - Unnecessary.
• Specter's Wail - Unnecessary.
• Death Pits of Rath - Seems unnecessary.

I find it odd that Scroll Rack , which is $20-30, is here amongst all the commons and uncommons. Do you own one?

Cards I would consider adding (some may be slightly beyond your budget, but they're good to have in mind):

• Sol Ring
• Mana Vault
• Nirkana Revenant
• Crypt Ghast
• Coffin Queen
• Dread Slaver
• Geth, Lord of the Vault
• Phyrexian Arena
• Necropotence
• Sign in Blood
• Murder
• Doom Blade
• Go for the Throat
• Gravespawn Sovereign
• Helldozer
• Phage the Untouchable
• Plaguebearer
• Pontiff of Blight
• Royal Assassin
• Undead Gladiator - Monetarily inexpensive way to filter your hand.
• Vengeful Pharaoh
• Zombie Master
• Sheoldred, Whispering One
• Gauntlet of Power
• Extraplanar Lens

Don't neglect mana ramp and removal. Both are important in EDH.

@Epochalyptik Lol, yes I do own the Scroll Rack . I have a box that's 5 rows wide and probably 800 cards long of stuff from ~Ice Age on up and all of the cards don't show rarity so I have no clue what might be worth a damn or not. My uncle started the collection and I have continued it as represented in my deck Grave Terror.

Thank you for list of cards that I will be looking into. Luckily enough I have a decent amount of them.

As a 'hasty' EDH deck (one made with cards on hand), I like this a lot. It certainly captures the feel of a zombie horde bearing down on you.

Suggestions for cards that might be good:

Patriarch's Bidding

Sudden Spoiling

Urza's Incubator

Strata Scythe

Mimic Vat

Jet Medallion

Syphon Flesh

Syphon Mind

Plague Wind

Cryptic Gateway

Intimidation

Grave Pact

Cover of Darkness

Attrition

Citanul Flute

Unholy Grotto

Cabal Coffers

Urborg, Tomb of Yawgmoth

Barren Moor

Bojuka Bog

Leechridden Swamp

Polluted Mire

Shizo, Death's Storehouse

Temple of the False God

Withered Wretch

Lord of the Undead

Noxious Ghoul

Fleshbag Marauder

Grave Defiler

Death Baron

Corpse Harvester

Bone Dancer

Gravecrawler

I use Thrax for my Commander too. I found something I like that really makes things interesting. Instead of running Jace, Architect of Thought , I run Nicol Bolas, Planeswalker . If Thraximundar is getting targeted too much, I just search out Bolas and drop him. Some people scoop, others try to fight him but that final can build fast and he can remove most of an opponents defensive options. Just a thought really, but you may wanna check him out.

Lordslyver66, If I had a copy I would definitely run him. Thanks for the suggestion. I know my brother has one so I may see if he's willing to trade.

Goblin Bombardment here could make your infinite sac combos infinite kill combos.

Dekord How? Where would I have infinite creatures without the mana? Both the Diregraf Captain and Deathbringer Thoctar work with the Phyrexian Altar + Gravecrawler to produce infinite damage / kills.

Rooftop Storm + Zombie + Gravecrawler + Goblin Bombardment

Ah, Rooftop Storm . I will definitely consider it :)
