Nethroi, Apex of Combo (EDH / Commander) [Revision 21]

Budget Abzan combo deck, will be improved with time!
PS: Nethroi is a useful reanimator spell in the command zone

Wincons:

1. Animate Dead + Leonin Relic-Warder (must be in graveyard!) + Blood Artist : Animate Dead brings back Leonin Relic-Warder from graveyard; with the ETB of Leonin Relic-Warder exile the aura; sacrifice Leonin Relic-Warder; Blood Artist trigger, and the aura comes back to the battlefield. You can go on infinite, killing opponents with Blood Artist triggers. (NB will work also with Cruel Celebrant, Corpse Knight or Zulaport Cutthroat)

2. Sun Titan + Angelic Renewal + Blood Artist + Viscera Seer : Sacrifice Sun Titan with Viscera Seer; Blood Artist trigger; sacrifice Angelic Renewal to bring back Sun Titan; Sun Titan ETB brings back Angelic Renewal. Then repeat the process. Viscera Seer can be replaced with any sac-outlet. If you use Greater Good, then it is preferable to use a different pinger, which will hit all opponents at the same time (for example Zulaport Cutthroat).

3. Sun Titan + Minion's Return + Blood Artist + Viscera Seer : same as wincon 2, but you don't have to sacrifice the enchantment to bring Sun Titan back.

4. Sun Titan + Fiend Hunter + Blood Artist + Viscera Seer : play Sun Titan; play Fiend Hunter (or if it is in the graveyard use ETB of the Sun Titan to put it back to the battlefield), and with its ETB exile Sun Titan; sacrifice Fiend Hunter to Viscera Seer, bringing back to the battlefield Sun Titan; Blood Artist trigger; with Sun Titan ETB put on the battlefield Fiend Hunter. Repeat the process.

5. You can replace "Blood Artist + Viscera Seer" in wincons 2, 3, 4 with Altar of Dementia: sacrifying the creature to the Altar you can mill your opponents.
