Teysa Karlov Aristocrats Combo (EDH / Commander)

This deck contains a large number of free-form, 2-3 card combos (some w/ and some w/out Teysa out) that enable instant kills on all opponents.

Deck revolves around infinite sac combos. In a controlled environment without any disruption, this deck will consistently win on turn 6-8, putting the overall power level of this deck at about 8.

Kill Pieces - all the combos in this deck will result in one of 3 states (maybe) more, and as long as certain conditions are met for each state, all opponents will instantly die.

1. Infinite Death Triggers: Blood Artist, Cruel Celebrant, or Zulaport Cutthroat will result in instant death. Grave Pact and Dictate of Erebos offer the ability to wipe opponents' boards if you need to buy time in case you can't go infinite that turn.
2. Infinite/A lot of Mana: Torment of Hailfire to instantly kill opponents. While doing combos, it's fairly easy to have a draw piece out (Smothering Abomination, Midnight Reaper, Mentor of the Meek, etc), and with multiple tutors it should be easy to hit this card.
3. Infinite Tokens: Blasting Station + token generation will storm off to kill all opponents. Otherwise, hit them for infinite damage next turn.

Main Combo Pieces:

Nim Deathmantle + Ashnod's Altar/Phyrexian Altar/Pitiless Plunderer: Any creature that creates tokens upon death or brings back creatures upon death will combo with these 2 pieces out, as long as saccing the creature + the tokens made generate enough mana to activate Nim Deathmantle. This will result in infinite death triggers, and potentially infinite mana and/or infinite tokens.

Darkest Hour + Teysa, Orzhov Scion: sac any creature to create an infinite chain of sacs. With Teysa Karlov or Anointed Procession out, this will also generate infinite tokens (2 for each spirit Teysa, Orzhov Scion creates).

Phyrexian Altar + Teysa, Orzhov Scion + Nether Traitor: sac Nether Traitor for B, sac the spirit for B, then pay B to bring Nether Traitor back from the graveyard. This loops infinitely, eventually allowing you to generate infinite mana in both colors.

Requiem Angel + Divine Visitation: all spirits from Requiem Angel enter as angel tokens, which will still trigger Requiem Angel.

Phyrexian Altar + Reassembling Skeleton/Nether Traitor + Requiem Angel: after saccing both creature and spirit token generated, bring creature back from graveyard. Nether Traitor will also generate infinite mana in the process.

Since many of the combo pieces can be rotated around, this deck retains a fairly high level of consistency even when some pieces are destroyed. Included are also some minor artifact recursion pieces in Myr Retriever, Buried Ruin and Workshop Assistant for recurring Ashnod's Altar/Phyrexian Altar/Nim Deathmantle after they're inevitably destroyed.
