[EDH / Commander] Sheoldred, the Zombie Queen

[crimsonking]

When playing monocolor, I always suggest to use Snow-Covered lands, so that you can use Scrying Sheets to get extra lands here and there.
snow-Covered lands also play well with Extraplanar Lens.
Also, Ghoulcaller Gisa can go infinite with Thornbite Staff and stuff like Phyrexian Altar.
Phyrexian Altar comboes with Gravecrawler (and Vengeful Dead or similar) too.
Other cards I'd put in your deck:
Urborg, Tomb of Yawgmoth (it plays well with Cabal Coffers)
Bojuka Bog
Volrath's Stronghold
Unholy Grotto
Myriad Landscape
Charcoal Diamond
Star Compass
Coldsteel Heart
Nim Deathmantle (comboes with Ashnod's Altar and a ton of stuff, Grave Titan among others)
Vampiric Tutor
Buried Alive (you simply can't make a reanimator deck without this one)
Corpse Connoisseur
Fleshbag Marauder (or the new Plaguecrafter, who unfortunately isn't a zombie)
Geralf's Messenger (another dude the wins you the game with Nim Deathmantle + Ashnod's Altar)
Coffin Queen (my favourite card, and she's a zombie!)
Lord of the Undead (by far the best zombie lord)
Nezumi Graverobber
Living Death
Twilight's Call
Triskelion (notorius combo with Mikaeus, the Unhallowed)
Damnation
Toxic Deluge

Revision 20

Added/removed cards:
+1 (SB) Liliana of the Veil

I've added Liliana of the Veil into SB strictly because it helps with the control, and I happen to own a foil, so I've chosen to put it in. I will be replacing [[Undead Warchief]] in the deck because I don't think it's worth the slot, but feel free to keep it in as it's a great option.

Revision 28

Added/removed cards:
-1 Midnight Reaper
+1 God-Eternal Bontu

It was a hard road with this one. 6 months I have been constructing this one, and I thought it was done up until I went to my pre-release for War of the Spark, and I pulled a promo Bontu. I didn't think much of her since she was spoiled, and only today when I really looked at her, I realized how beautiful she was not only in a deck full of creatures to sacrifice, but as a Commander. She permits the freedom to card draw into whatever I want, and gives ease of ramping my board state by filling my hand when I need it. I look forward to playing this deck as soon as I get the remaining cards. I am very proud of myself for this deck, and it might end up being my favorite EDH deck that I will ever make in my entire life.

Revision 34

Added/removed cards:
+1 Ensnaring Bridge
+1 Winter Orb

Changed amounts:
-2 Swamp

[crimsonking]

You play many high mana-costed cards but only 30 lands. Many cards are pretty cool by themselves, but I don't see any relevant sinergy.
You didn't follow any of the advises so far, so I understand you're having fun with your deck as is. And that's perfectly fine, just be aware that your deck is overall weak.

Hi @crimsonking,

I just had the chance to look at your comment, (for some reason i wasn't getting notifications about any comments on my deck), and I went through all those cards you suggested. Focusing on the cards that exile opponents graveyard or reanimate all graveyards to the battlefield under their owner's control, not good for how my deck is. I intend to steal cards from my opponents graveyard if if I dont already take the cards when they die. I also dont want Damnation, because saccing my own creatures for whatever purpose I intend to use them for, kills my opponents creatures also, not to mention, if anything on my opponents side gives their creatures indestructible, my sac outlets will still kill my opponents creatures. certain cards that you mentioned for combos just arent worth it. Triskelion and Mikaeus are spots in the deck I can't afford to give up. Nim Deathmantle and Ashnods altar puts my creatures in a negative in order to reanimate my stuff by 2 mana each time. Not sure at all how Ghoulcaller Gisa, who has to tap in order to be activated, can go infinite with Thornbite Staff at all. Zombie Tokens are never placed in the graveyard, so I would have to reanimate the creatures placed in graveyard to go infinite. I will however put Thornbite Staff into the deck because it permits me to use Ghoulcaller Gisa more often. There were many other cards that just didn't work well with the way I designed the deck.
