-Archfiend of Depravity: A new addition to the deck, the few times i've played it it's been very impactful, stopping my opponants from doing much and giving me time to build my field. It also works quite well as (if it survives) it forces your opponents to sacrifice all their worst Creatures, allowing you to use your targeted removal spells on their better ones (maybe even using the Toshiro triggers provided by the sacrifices). It's also a pretty decent body, 5/4 Fliers can get in for serious damage, and wear Equipment very well!
-Bloodgift Demon: Phyrexian Arena on a big thicc flying stick! Great consistent card draw (if he doesn't get killed) and another good 5/4 Flying body to attack/block with.
-Chainer, Dementia Master: A new addition that I'm also using as an occasional alternative commander... when I'm feeling a bit spicy :) While he is fragile, he has some insane potential when you have enough mana and life to spare! I run plenty of Creatures with good ETB effects, so even if he gets killed (Exiling all resurrected Creatures along with him) I can usually get some value! Some great targets in the deck include Gonti, Lord of Luxury, Gray Merchant of Asphodel, Noxious Gearhulk, Overseer of the Damned and Sepulchral Primordial!
He can also be used as pseudo Graveyard Hate, as when Chainer dies, all Creatures he resurrected get Exiled!... although this can also be a downside if you wanted to bring back those Creatures again yourself.
-Crypt Ghast: One of the most powerful cards in the deck. Essentially doubling my mana potential, and giving me a way to use it with Extort. If it sticks around it can allow Toshiro to flashback an entire graveyard of Instants, or fuel a game-winning Torment of Hailfire.
-Drana, Kalastria Bloodchief: Drana is great! the floor of a 4/4 Flier for 5CMC is ok, but her ability acts as a fantastic Mana Sink that takes out key Creatures (even Indestructible/Regenerating ones) while pumping herself, and giving you a way to trigger Toshiro so you can recast Instants from your Graveyard without spending a card.
PRO TIP: Even if there are no other Creatures in play, for 5 Mana she can use her own ability on herself to turn into a 7/1 Flier, which hits pretty hard, but can leave her vulnerable...
-Dread Presence: An awesome cheap Creature. He just does everything. Card draw or removal of small Creatures whenever you play a Swamp is fantastic. I'll usually try to play him followed up by a Swamp in the same turn, so I can trigger him at least once before anyone has a chance to remove him. Most of the time I'll use his trigger to draw, unless there's a really good target for the damage, or I'm running dangerously low on life.
PRO TIP: Wayfarer's Bauble and Myriad Landscape are ways to put multiple Swamps into play on a single turn, allowing you to use Dread Presence to kill larger creatures by repeatedly hitting them with 2 damage! You can also wait to crack them until Dead Presence is in play, so you get a lot of value out of him before anyone has much of a chance to kill him off!
-Gonti, Lord of Luxury: Just a great value card. For 4 mana, it gives you a 2/3 Deathtouch Creature, which really dissuades attacks, along with the choice of a card from an opponents deck! This is a great way to get access to effects that Mono-Black usually can't, like Artifact and Enchantment Removal. He's also an excellent target for Mimic Vat, 3 mana to draw the best of top 4 cards of an opponents deck, plus a 2/3 Deathtouch chump blocker or attacker!
-Gravebreaker Lamia: Another card that just seems to do it all! A big Lifelink Creature that makes it cheaper to flash spells back with Toshiro, who also puts a spell into your graveyard! The best targets for her "tutor" ability in my deck are Dismember (which she lets you flashback for 0 mana using Toshiro), Stinkweed Imp (lets you fill your graveyard even more by Dredging it with your next draw) or really any other Instant spell!
-Gray Merchant of Asphodel: A great source of lifegain that can potentially act as a Wincon if you have enough Black devotion, or ways to repeatedly recur him. I run lots of Creatures with in their CMC, so he often drains for 6 or 8 when he hits the board. A great Mimic Vat target as the token that the Vat produces has the Mana Cost of the copied card, so the token copy of Gary will always drain for a minimum of 2 for each opponent!
-Mindwrack Demon: A cheap creature with fantastic stats that has good Black Devotion and wears Equipment really really well! He also fills my graveyard with Instants I can flash back with Toshiro, and Creatures I can recur!... So what's the downside?...well...he punches you in the face each turn if you don't have Delirium.
STATS:By himself, on average, he puts around 3 card types into my graveyard, because I have a balance of Lands/Instants/Creatures/Artifacts/Enchantments/Sorceries, and I do have a few Artifact/Enchantment Creatures, which count as 2 types when in the graveyard. Creatures, Instants and Sorceries tend to make their way to the graveyard naturally, so if he mills a land, Artifact or Enchantment, you'll probably be fine. You can also hold off on playing him until you already have a few card types in your graveyard, if you're health is under pressure.
-Harvester of Souls: I love and hate this card. He usually either draws me 0 cards, or like... 20... IF I remember his trigger, which I often don't... He's a great Creature that, if left alive, can essentially close out games by giving you insane card advantage. He also works as Board-Wipe insurance because he still "sees" every other Creature die during a Board-Wipe, and subsequently draws you a huge amount of cards, which usually lets you recover easily!
-Hooded Blightfang: A really nice cheap, tough Creature that holds back early attackers from just chipping in. He acts as "removal bait" as people don't usualllly want to have to trade him for a Creature with 4+ Power! He also plays well with quite a few of my other Creatures as they also have Deathtouch!
-Isareth the Awakener: An interesting Creature that works as a good attacker/blocker in the early game due to her good stats, but also works well in the late game as Deathtouch means she's usually going to trade up. Her second ability also works well late in the game as she usually trades for a bigger Creature, while giving me the opportunity to recast another Creature from my graveyard. That... or she eats a good removal spell before I get to attack with her, which is also a pretty good fail case for 3 mana!
-Leaden Myr: A nice little Black mana dork that can chump block and wear equipment! Also, being colorless means he can block Creatures with protection from Black!
-Nightmare Shepherd: This guy is awesome. First off, 4/4 Flying for 4CMC is perfectly fine! This deck runs plenty of Creatures that are still really strong as 1/1 tokens, or have great ETB effects. It's a shame that he exiles the Creatures he turns into tokens, because we often want to resurrect Creatures from our grave, but I usually find that he acts as "removal bait" because nobody wants to have to kill your other Creatures twice...
PRO TIP: Nightmare Shepherd works very well with Commanders, especially Toshiro. If your Commander dies while he is in play, you can choose to Exile the Commander to make a 1/1 token copy, then just send your commander back to the command zone, keeping a 1/1 token copy with the same abilities, and even CMC, so it counts towards Devotion!
-Nullpriest of Oblivion: A really nice versatile Creature from Zendikar Rising. A good turn 2 play as it's likely to get in for a lot of hits with Menace, and the Lifelink means it's going to have a decent impact on life totals. In the late game, it's a fine 6 mana play that can get you back a Creature from your graveyard, and this deck has plenty of good Creatures. It wears Equipment like Lashwrithe or Runechanter's Pike quite well, gaining you a bunch of life and forcing double blocks. Also a great late-game target for Shred Memory, if you don't have enough Mana to fire off a lethal Torment of Hailfire...
-Noxious Gearhulk: Removal and lifegain on a big evasive stick! A new addition that just seems to do everything for a pretty reasonable cost. It also wears Equipment quite well, demanding double blocks, which are likely much harder as it kills something with its ETB. Another fantastic Mimic Vat and Chainer, Dementia Master target!
-Overseer of the Damned: More removal on a big evasive stick... that brings an army of zombies with it! It is pretty expensive at 7 mana, but it can really turn a game around. It also works as Board-Wipe insurance, as it will "see" every other Creature die, leaving you with an army of zombies after everything else dies! The perfect Mimic Vat target!
-Palladium Myr: Worn Powerstone on a stick. Like Leaden Myr, a good mana-dork that can chump block, wear equipment and block Creatures with Protection from Black. Works well in this deck as I have plenty of good 5 and 6CMC spells, so getting to play one on turn 4 is excellent!
-Sepulchral Primordial: In 1v1, it's ok, in 4v4, I would think it could be muuuuuch better. It does what it says on the tin, 5/4 Intimidate + a Creature from each opponents graveyard is very strong, and depending on the Creatures you get, can win you games on the spot. Another fantastic Mimic Vat target!
-Sidisi, Undead Vizier: A new addition I'm hoping will give the deck some more consistency. She can target herself with her exploit ability, essentially turning herself into a 5CMC Diabolic Tutor, however if she (or whatever you target with Exploit) is killed at Instant speed while the exploit ability is on the stack, you won't get the tutor effect, so be careful! She can also be used to "trade" a weaker creature for a tutor effect (Solemn Simulacrum is a perfect target), and a 4/6 Deathtouch body is pretty good defensively, and great offensivly when equipped with Runechanter's Pike or Shadowspear!
PRO TIP?: She has a kind of "combo" with Chainer, Dementia Master. Target Sidisi with her own Exploit ability, then tutor for Chainer, who can be used to repeatedly reanimate Sidisi for and 3 life, giving you a repeatable tutor effect. It's not the most efficient combo, and it can be ground to a halt if someone kills Chainer with instant speed removal in response to Sidisi exploiting herself. It's only really viable in a stalled game, where you need a few cards to get a win, otherwise just using Sidisi to tutor for a finisher like Torment of Hailfire is usually the way to go!
-Solemn Simulacrum: A new addition, I'm hoping he will help bring some more consistency to the deck. Also a decent Mimic Vat target, acting as repeatable Ramp, and Card Draw if you find a way to have the token die!
-Steel Hellkite: A pet card of mine that also fits into Mono-Black really well as it's a way to destroy Artifacts and Enchantments. It also totally hoses Tokens as they usually have a CMC of 0. It also makes good use of the huge amounts of mana this deck can produce, the colorless "fire-breathing" effect it has can easily finish someone off.
-Tymaret, Chosen from Death: Excellent repeated graveyard hate, that also gives a nice bit of lifegain. He's great in my meta, but if nobody else is doing anything with their graveyard in yours (which is VERY unlikely), then he's actually actively bad in this deck.
