Yuriko, the Fist of Shadows (EDH / Commander)

Full Ninja Tribal, no changelings allowed this is not a competitive deck it's just meant to be annoying. Basically just hit them draw mana rocks to do mediocre damage and set up to take 8 extra turns in a row, also the reveal from the extra turns hurt a lot >.>

Muddle the Mixture, Shred Memory, Dimir Infiltrator are for tutoring for Tetsuko Umezawa, Fugitive, Bitterblossom, Hidden Strings, or Scroll Rack or for their default uses Shred Memory is good for exiling the titan Eldrazi from reusing themselves. Vampiric Tutor and Mystical Tutor are obviously for Temporal Mastery at an opponent's endstep or if they try to mill the top card of library after I used something like Dream Cache, Ponder, or Portent you can throw a Nexus of Fate up there so it just shuffles back. Something like Perplex can be used as well for tutoring and countering but I don't find it to be reliable as a counter as it gives your opponent a choice to sacrifice their hand to save their spell while it may sound good in theory to knock out their hands, it's never a good thing to give them a choice. Same reason why Temporal Extortion is in the sideboard, not once have I managed to get the extra turn for it someone always pays anywhere between 1 and 20, both of which are meaningless if you're going crazy since you can deal anywhere between 3~50 damage off reveals uwu

Willbreaker+Cauldron of Souls/Unnatural Selection was there cause at one point I wanted to take everyone's creatures and turn them into ninjas too. The combo worked as not only did it open anyone to attack, it also made everyone hate me so... I took them out.

Xenograft, Conspiracy, and Arcane Adaptation are just there literally for the Moonblade Shinobi, Bitterblossom, and Call of the Nightwing tokens. They can easily be replaced for something more... exotic?

Spark Double, Sakashima the Impostor, and Helm of the Host are... Yuriko Clone-jutsu that bypass legendary rule without needing Mirror Gallery. Hitting with one ninja and revealing 3 cards off is a really cool trick, sometimes you can reveal like 20 cards because well... you took 5 extra turns and each turn you got another Yuriko but hey whatever.
