Creatures
Blood Artist- This deck wants to murder creatures and spends lots of life to do so. This guy gets back some of that life lost and then some.
Burnished Hart- Ramp guy. Black cares about swamps and this guy gets them. We can reanimate him to thin our deck and provide us with tons of mana.
Butcher of Malakir- Grave Pact that we can reanimate. Excellent card
Crypt Ghast- Doubles our mana, gains us life.
Dimir House Guard- This guy is insane in our deck. He tutors for CMC 4 cards and is a free sac outlet that we can reanimate. This covers a lot of ground in 4 drop: Crypt Ghast Disciple of Bolas Faceless Butcher Grafted Exoskeleton Grave Pact Graveborn Muse Liliana of the Dark Realms Mindslicer Mutilate Nevinyrral's Disk Slum Reaper Whip of Erebos.
Disciple of Griselbrand- Not quite a free sacrifice, but it does get us a resource we need.
Fleshbag Marauder- First of the edict creatures. This guy gets around pretty much everything but Sigarda and Tajuru Preserver. Those cards can suck it.
Gray Merchant of Asphodel- Stabilizes us really well and can just win us the game by recurring it or comboing off. Our devotion is usually substantial as well.
Massacre Wurm- Get wrecked token player. The life loss is a bigger deal than you might think to the non-token decks as well.
Mindslicer- This is such an asymmetrical result to a symmetrical effect for us. We operate heavily out of the yard so pitching our hand usually isn't a problem while other decks are just in top-deck mode.
Myr Retriever- Gets us back our utility artifacts.
Sheoldred, Whispering One- Does a reasonable Chainer impression while pressuring opponents. A good card to find if we don't have access to Chainer for some reason.
Sidisi, Undead Vizier- I hear Demonic Tutor is a good card. This in your yard with Chainer is BBB, pay 3 life: Search for any card and put in your hand at instant speed. This will find whatever you need.
Steel Hellkite- One of black's only weaknesses is not being able to deal with enchantments and artifacts. This is one of the few ways we can get rid of problematic permanents.
Wurmcoil Engine- A decent beater that refills the life bar. The tokens it makes when it dies are easily abused with any sacrifice effects and can be amassed by looping it.
Artifacts
Altar of Dementia- Free sac outlet. We want to target ourselves if we need gas because the creatures in our graveyard are easier to get into play than creatures in our hand.
Expedition Map- Usually just Cabal Coffers #2
Grafted Exoskeleton- Some folks don't like infect, but its an efficient way to deal with someone gaining infinite life. This card is a holdover from when I didn't run infinite combos and is a candidate for replacement.
Nevinyrral's Disk- Larry's Disk is another way for us to clear the board of problem enchantments and artifacts. We have to use what is available to our color.
Skullclamp- Draws us silly cards.
Sorcery
Living Death- Probably my favorite black card. Has lots of applications, but you do need to be cognizant of what is in your opponents' yards.
Mutilate- Who needs Damnation? Gets around indestructible and even Sigarda, tutorable with Dimir House Guard. Love this card, the original Torment art is mandatory.
Toxic Deluge- Best boardwipe available in black.
Instant
Planeswalker
Liliana of the Dark Realms- This deck wants to hit all it's land drops for the entire game. She gets us there plus can remove something in a pinch. Given how often we want to be using her +1, it's pretty common to ult her.
Enchantment
Dictate of Erebos- Grave Pact #2
Grave Pact- This card is almost our second commander. Doubling up Fleshbag triggers is an easy way to clear the board in short order. Excellent card in most black decks but it shines here.
Necropotence- The fairest thing you can do with this card is draw to seven at the end of each of our turns. Be careful how hard you dig because the discarded cards will be exiled. This card is amazing.
Lands
Bojuka Bog- Sometimes its more dangerous for someone else to have access to their own graveyard than for us to have access to it.
Cabal Coffers- Best land in the deck, a top tutor target. The most expensive card that I would consider integral to the deck.
Crypt of Agadeem- Not as busted as the other lands with activated abilities for 2, but we can get some good mana from this later in the game. I might try out Deserted Temple in this slot.
Maze of Ith- Protects us from big beaters.
Nykthos, Shrine to Nyx- As a color, black cares more about your lands being swamps and your spells costing black than any other. It rewards you with incredibly powerful cards if you can pay it's very heavy black mana requirements. Necropotence is the prime example of this. Nykthos takes that and turns it into an amazing resource. Our second best source of B from a land.
Thespian's Stage- Usually copies Coffers.
Urborg, Tomb of Yawgmoth- Makes our utility lands tap for B, makes Coffers insane.
Vesuva- Usually copies Coffers, can be a swamp in a pinch.
Volrath's Stronghold- Another way to recur creatures that doesn't take a spell slot.
30x Swamp- The real heroes.
