@FancyTuesday what would you suggest removing?

Corpse Connoisseur - Right now he only really does anything special with three cards in your deck; Necromancy, Whip of Erebos, and Makeshift Mannequin. With Lord of the Dead he's a really expensive zombie tutor. That's a pretty rare dependency. Without more of a reanimation focus I'd cut him. If you're looking for a tutor effect there's Beseech the Queen , otherwise I'd slot in Corpse Dance here.

Sign in Blood - With card draw spells you have to remember that it loses a card in efficiency in replacing itself, and a single, non-repeatable draw for two life isn't really worth a slot in EDH. I'd put Bloodghast here.

Witchbane Orb - This might depend on your meta, but as a one-of effect it's not great. What effects that target you are you desperate to avoid, and how often are you going to have this one answer in 99 cards on the board to save you? I'd rather see All is Dust in my hand.

Ashes to Ashes - If you have the cash to drop on Karn Liberated he fits well here. Ashes is cheap but this is EDH, where a 7 drop is practically "mid game." Not only does Karn stick around to keep wrecking house, he can intimidate your opponents into not playing their nice things.

Illusionist Bracers - This card is a strong case of "win more," meaning that if it's really doing anything then you've probably already won, otherwise it's just farting around on your board.

Odds are you won't have multiple good targets for Gisa, so her second use will probably be killing a zombie token made by the first activation. You can argue that the zombie might be a 4/4 with multiple Lord buffs but then you're adding dependencies, and even then it only nets you 3 more zombies. I value dependability/consistency over making things great when they're already going good so I'd run Reassembling Skeleton here.

Magewright's Stone - See above. Nether Shadow gives you another creature.

Extraplanar Lens - Only checks names so Urborg doesn't help you and it may help your opponents. Expedition map effectively doubles your chance of seeing Cabal Coffers in a game, which will often produce as much if not more mana than Lens without setting you back a land drop. If by chance you already have Coffers out you can fetch Urborg or Vesuva instead.

I should note that even though I'm not wild about Magewright's Stone I like Thousand Year Elixir and Thornbite Staff. Ability haste can be very important when you're building around your Commander's activated ability, and Thornbite Staff has great synergy with your Commander, practically giving you as many zombies as you have black mana to spit them out.

LOL wow i just started watching Tokyo Ghoul, and this is what I find. +1 good sir.

I even have custom tokens I'll probably in add them to the description at a later point
