Feed the Swarm

One of black's extraordinarily rare cards that can remove an enchantment of your choice, Feed the Swarm is cheap, with a downside that ꩲmatters less when you have 40 life to start the game.

Deadly Rollick

The value of exiling a creature instead of destroying it, combined with Deadly Rollick's likelihood to be cast for free, all at instant speed, make it an easy inclusion.

Infernal Grasp

Unconditional creature removal at instant speed for only two mana is a great deal, and the value brought far out🔯weighs the minor loss of life✃.

Ravenous Chupacabra

The drawbacks of Ravenous Chupacabra, a mana value of four and sorcery speed, are somewhat negated when you consider how it interacts with cards that return it to the battlefield, such as Kaya's Ghostform or Reanimate.

Go for the Throat

Despite certain artifact creatures undeniably being large threats, they still make up the minority of most decks you'll be facing, and Go for the Throat is otherwise as valuable as Infernal Grasp.

Murderous Rider

Murderous Rider's capacity to destroy planeswalkers in addition to creatures is🎐 useful, and being able to cast it as a creature with decent power and toughness afterwards can come in handy.

Damnation

Damnation is black's color-shifted counterpart to the first board wipe ever printed, Wrath of God, and both still hold up to this day as efficient creature sweepers.

Toxic Deluge

Toxic Deluge has everything you could want from a board wipe: It gets around indestructibility, it only costs three mana, and you have a limited ability to choose what creatures to kill in꧂ this manner by paying less for its additional cost.

The Meathook Massacre

Despite The Meathook Massacre potentially costing a lot of mana to do its job as a proper board wipe, its secondary benefits give the card enough flexibility to make it a s𓂃taple.

Massacre Girl

Five mana might seem steep for a conditional board wipe, but Massacre Girl's ability can be triggered again later using the same means as Ravenous Chupacabra. In addition, she provides a 4/4 creature body with menace, and will almost always end up as the last one standing.

Black Sun's Zenith

The key difference between Black Sun's Zenith and the other board wipes here is that it places counters on the creatures instead of temporarily giving them -1/-1, meaning you can situationally cancel out +1/+1 counters with it, or just power down the entire battlefield if you don't have the mana to make it a real wrath.

Mutilate

Easil♋y at its strongest in mono-black decks, Mutilate will often rid꧟ the board of all but the toughest creatures.

Phyrexian Arena

An e🎃xtra card on each of your turns is well worth the single point of life that you lose, and Phyrexian Arena quickly 🥂becomes an advantage that has to be answered by the other players.

Necropotence

A contender for one of the strongest black cards ever printed, Necropotence leaps from great to unparalleled when you🧸 have so much more life to work with wꦯhen compared to a one-on-one format.

Dark Confidant

The loಌwest mana value card draw staple also punishes you the hardest as a result. Playing a Dark Confidant is like playing with fire: You can do a lot of damage with it, but you might get burned.

Greed

Ironically, the mos♛t budget-friendly option for repeatable card draw is Greed. Unlike the other staples of its kind, Greed requires you to pay mana and life, making it harder to exploit.

Ad Nauseam

Found frequently at the center of cEDH decks, Ad Nauseam is treated as a win condition more than it is a card draw engine since the hyper-competitive top decks will 🌸almost always achieve victory after it resolves.

Demonic Tutor

Magic: The Gathering's first ever tutor has found its permanent home as a staple in Commander, being banned, restricted, or never printed in any other official format due to its strength.

Diabolic Intent

The less-powerful brother of Demonic Tutor, Diabolic Intent still brings incredible valu𓆉e, especially if you have token creatures to sacrifice fo🍒r its additional cost.

Diabolic Tutor

The slowest of the tutor staples, Diabolic Tutor is still a good addition to decks on a budget or in slower games, and sets ꧙the bar for the minimum capabilities of a black tutor staple.

Grim Tutor

Better than Diabolic Tutor, but nowhere near the power level achieved by other tutor staples, Grim Tutor is often ove🌼🍸rlooked when upgrading decks.

Vampiric Tutor

Although Vampiric Tutor only puts the card on top of your library, due to the ability to cast it as an instant, you can play the spell on the end step dire🐷ctly before your turn to draw the car𝔍d right away.

Imperial Seal

Unlike Vampiric Tutor, Imperial Seal has to be cast as a sorcery, which means that you're at a much higher risk of someone disrupting you drawing the card that you search for. However, only one mana and two life is worth the risk, especially since black has few issues drawing cards at instant speed.

Entomb

Despite not actually placing the card you searched for into your hand or on top of your library, Entomb enables very powerful graveyard strategies that are present in🐬 almost every black deck.

Buried Alive

Three Entombs in a trench coat make a card that can reach a higher ceiling at the cost of being a bit clumsy. The additional mana cost makes it harder to use the entombed cards the same turn they've been tutored for.

Reanimate

Comboing nicely with cards such as the aforementioned Entomb, Reanimate offers a cheap way cheat a creature's mana cost by first placing it into your graveyard and then spending life instead of mana to cast it. Barring that, it still manages to be a low-cost option of bringing a creature back to life, even from your opponent's graveyard.

Victimize

Sacrificing a low-cost creature 🌱to revive two much more valuable creatures is a nice option at only three mana.

Animate Dead

Despite its confusing updated rules text, Animate Dead's effect is rather simple and beneficial. Casting it means placing a creature from a graveyard onto the battlefield and attaching Animate Dead to it. If Animate Dead leaves the battlefield, you sacrifice the creature that had been brought back.

Malakir Rebirth

Granting pseudo-protection at instant speed, Malakir Rebirth can also be played as a land,🀅 allowing you to slot it into any deck as a replacement for a basic Swamp.

Mortuary Mire

Similar to Malakir Rebirth, Mortuary Mire being a land makes th♏e relatively weaker benefit it grant𒉰s still worth running.

Dark Ritual

Printed in the original 1993 Alpha set of Magic: The Gathering, Dark Ritual is both widely-available and widely-applicable to mono-black decks. Since you're already restricted to casting only black and colorless spells, the three black mana that Dark Ritual makes will be handy in casting any of them.

Cabal Ritual

Filling your graveyard in mono-black isn't the easiest task, but it's not exactly difficult either, and Cabal Ritual will often make you five black mana later in the game, while still maintaining some use early on if you're short a land drop.

Culling the Weak

Combining two of black's main ramp pillars, Culling the Weak does require that you sacrifice a creature, and thus has a narrower use case since you don't want to sacrifice a creature that would have cost four or more mana to cast in the first place.

Cabal Coffers

Between the iconic art and its place as a unique ജmethod of ramping, Cabal Coffers makes the most sense in mono-black decks.

Cabal Stronghold

The weaker version of Cabal Coffers, Cabal Stronghold might cost an additional mana to activate and only count basic Swamps, but it still has its place in most mono-black decks that will win the game with high-mana spells.

Crypt Ghast

In the same vein as Cabཧal Stronghold, Crypt Ghast is most ♋useful in mono-black decks that want to finish by casting high-mana value cards.

Phyrexian Tower

Sacrificin🐷g a creature in black is less of a risk than some other colors due to its recursion cards, and the extra mana made is worth the tradeoff.

Revel in Riches

Both a source of ramp and a potential win-condition, Revel In Riches does rely more strongly on your opponents' creatures being destroyed than would normally be acceptable. However, since it creates treasure tokens as opposed to directly adding mana, you are more free to utilize that ramp at your own pace.
