I would describe this as a "75%" deck. It has a lot of explosive potential, but intentionally eschews most tutor effects to make room for more fun/pet cards and to make games play out differently. It has a lot of redundant effects, making it resilient to most hate, even exile and most graveyard hate. It is soft to Rest in Peace, Leyline of the Void, and Anafenza, the Foremost. None of these effects are super popular at more casual tables, but if you sit down and you're staring at Anafenza in the Commander slot of a deck across the table, I'd recommend just switching your deck. She shuts off so much of what the deck does, and only Teysa, Orzhov Scion can meaningfully interact with her.
If you want to take this deck in a more competitive direction, the number on suggestion would be cutting some of the more expensive cards for more tutors and more cheap interaction. Cards like Requiem Angel, Divine Visitation, Extractor Demon, Kokusho, the Evening Star, Dictate of Erebos, Sadistic Hypnotist, and Immortal Servitude are the most expensive versions of largely-redundant effects, and could easily be replaced by cheap tutors like Demonic Tutor, Vampiric Tutor, Imperial Seal, Enlightened Tutor, Steelshaper's Gift, Recruiter of the Guard, and Entomb, or cheap interaction like Swords to Plowshares, Vindicate, Fragmentize, Disenchant, Path to Exile, Anguished Unmaking, Wispmare, or similar.
If you want to take the deck in a more casual direction, I'd recommend removing the few tutors it does run (Stoneforge Mystic and Relic Seeker) along with some of the infinite combo pieces like Nim Deathmantle, Nether Traitor, and Requiem Angel or Divine Visitation. In their place, add more expensive, splashier effects like Butcher of Malakir, Ashen Rider, Yosei, the Morning Star, Overseer of the Damned, Demon of Dark Schemes, Massacre Wurm, Harvester of Souls, Martyr's Bond, or similar.
Having free, repeatable sacrifice outlets is key for turning on your dies effects at-will
These are your primary sacrificial targets. They largely produce tokens on death, some of them give other benefits
These let you turn sac fodder into additional cards.
Getting additional tokens on death can rapidly expand your sacrificial prowess. Teysa and Requiem Angel are two of the most attractive because they can trigger off of some tokens. Teysa triggers off of any Afterlife tokens as well as those from Doomed Dissenter, Xathrid Necromancer, Flesh Caver, and others. Requiem Angel triggers off of any non-spirit token, like Zombies or Vampires generated from most non-Afterlife fodder.
Hallowed Spiritkeeper and Elenda are special cases. They don't give additional tokens from other things dying, but a sac chain will generate a lot of Elenda counters and bodies in the graveyard for Spiritkeeper, making them a great final sacrifice to create a huge number of tokens. Elenda is truly absurd because her counter-gaining will be doubled (and she triggers from any deaths, even tokens your opponents' from your Gravepact effects) as will her token generation on death. It's not unusual to see 30+ tokens from an Elenda sacrifice.
These are the cards that are most likely to swing a game almost immediately.
The mass recursion spells will regularly dump a bunch of creatures onto the board, including a sac outlet and a Blood Artist effect. They're chosen over traditional mass recursion spells like Living Death, Twilight's Call, and Patriarch's Bidding because the low curve allows us to make these into one-sided mass reanimates. Rally is by far the strongest, as it can be used in response to a Bojuka Bog or Tormod's Crypt activation, and casting it with X=3 or 4 will give you back basically your entire graveyard - it does require that you have a sac outlet handy, however, as without one it ends up exiling your dudes.
Pitiless Plunderer is just straight insane. It triggers off of even tokens, and Teysa doubles it. This means that with Teysa out, sacrificing a single Afterlife 1 guy and the tokens that come from it nets you 6 treasure. Throw in a draw engine and you easily churn your entire deck.
Deathrender does something similar, letting you drop creatures in from your hand for free. Combine it with a draw engine and sac outlet and you can experience some serious churn and rapidly kill the board. Remember that with Teysa, it triggers twice per death, meaning you can drop in two creatures and have the second one end up with the Deathrender, which is good for dropping in creatures you want to stick around, like Blood Artist.
For the most part, the deck will win via non-infinite sacrifice chains, with dozens of creatures hitting the graveyard triggering Blood Artist and friends. However, sometimes, combos will come together that will win the game on their own.
Nim Deathmantle is probably the most likely culprit for infinite combos. Any creature that makes a token on death, even without Teysa in play, plus an Ashnod's Altar, makes infinite sacrifices. Phyrexian Altar can be substituted in for things that make multiple tokens. Pitiless Plunderer plus any sac outlet also works, possibly with Teysa support.
Nether Traitor is another card that combos with a lot of things. Phyrexian Altar or Pitiless Plunderer plus any sacrifice outlet, combined with any of the cards that make tokens when any creature dies, lets you infinitely cycle Traitor in and out of the graveyard.
The final combo is more of a cute pet combo than anything reliable. Divine Visitation functions as a decent win-condition on its own, turning a handful of tokens into an Angel death squad. But combine it with Requiem Angel, and every Angel that dies creates a new Angel, granting infinite sacrifices.
Blood Artists and Gravepacts
With all of these creatures dying constantly, the deck does need a way to turn that into a win condition.
Gravepact and Dictate of Erebos let you keep opposing boards clear.
Blood Artist, Zulaport Cutthroat, Vindictive Vampire, and Falkenrath Noble all turn dying dudes into damage, quickly draining out the board.
Extractor Demon can self-mill to set up big recursion spells, or can turn into a kill when critical mass is reached.
