Yarok, the Desecrated (Ramp, Combo, Ouphe) (EDH / Commander)

Plan A: Peregrine Drake combo

Plan B: Ghostly Flicker nonsense

Plan C: Fair Magic with Avenger of Zendikar or Field of the Dead, I guess?

With Yarok in play:

-infinite mana and etb rebuys for other creatures with Peregrine Drake and either Shrieking Drake or Venser, Shaper Savant. Bounce all your opponents’ permanents with the latter and lock the game, and/or use this mana and your other resources to find Finale of Devastation, build a board, and win the game. There are many, many different ways this can come together.

-Infinite mana with Drake, Ghostly Flicker, Mystic Sanctuary, and one of Tatyova, Benthic Druid, Guardian Project, or Elvish Visionary/Ice-Fang Coatl/Risen Reef/Coiling Oracle (hereafter “etbD”):

Setup: Flicker Sanctuary and Drake, top Flicker and (optional) another instant or sorcery card. Resolve two draw triggers (from Flicker with Tayova/Project in play or from casting etbD after flicker).
Loop:
Flicker Sanctuary and etbD (or, optionally, something else if drawing from Tatyova, Project— mind how many draw triggers you create, though). Stack triggers such that: 1st Sanctuary trigger, top Flicker, resolve 1st draw trigger, Flicker Drake and Sanctuary, resolve new triggers so Flicker is topped. Resolve 2nd draw trigger, then 2nd Sanctuary trigger (top anything or decline, doesn’t matter). If drawing from etbD, Flicker that and Drake. Repeat loop.

-Lotus Cobra/Tireless Provisioner, Sanctuary, Ghostly Flicker, and Tayova or something idk. Various ways to go about it.

Without Yarok in play:
-Infinite mana with Peregrine Drake, Eternal Witness, Ghostly Flicker
-Lotus Cobra/Tireless Provisioner, Ghostly Flicker, Mystic Sanctuary and another land with Tatyova in play.
-Deal an arbitrary amount of damage to yourself with Lotus Cobra/Tireless Provisioner, Ancient Tomb, Eternal Witness, and Ghostly Flicker.
-etc etc etc

Even without going infinite, Lotus Cobra or Tireless Tireless allow you to have some absurd turns very quickly.

Power-level: 7 or 8/10 (sub-cEDH; able to win in turns 4-6 pretty consistently, has protection and redundancy, but unable to win before turn 3; somewhat reliant on commander that has a significant mana cost; playing some cards that don’t directly contribute to main plain or are below power level)
