Not unlike Najeela, her tribal appeal isn’t worth the opportunity cost of going “real” tribal.

Deck having her at the helm usually want to make her single triggers count, providing cheap evasive creatures (eg Slither Blade ) and possibly a way to bounce her back to the hand so she can be played again for the trigger. She can get rolling with a lucky shot or two for a time warp effect (or not so lucky with Mystical Tutor and the like). And if she can get through, Doomsday or Insidious Dreams for stack of extra turn spells usually can go for the game.

Basically think of her as a somewhat weaker dimir Edric, Spymaster of Trest ; evasive combat dmg for extra turns and value.

Now, IMO she isn’t just another Edric. It would be a stretch to call Edric strictly better, but I think he is significantly better. Green also compliments blue better than black here by getting Edric the needed pieces to combat stax, recur extra turns spells and the ramp necessary to cast 5+cmc spells by t3-4. Black provides tutors and some creature removal, but I don’t imagine it living up to what green offers here. Also, Edeic is less complicated to milk for advantage. Re-playing Yuriko would require constant mana expenses to keep things rolling and hence would slow you down. Also, she digs slower than Edric. I didn’t test optimized competitive Yuriko, but without tutors to go for Doomsday or Dreams, she seems far slower and far less explosive than Edric.

However she clearly can do more than mid-power generals. With a tutor (which black has) and an open opponent, she can end the game without passing the turn (in one turn effectively). She can get rolling as early as t2 consistently, requiring only an attacker and UB mana. Finally, she has a clear wincon and a value engine sitting in the command tone, making the deck run smoothly off of her alone if need be.

High power seems to be the place for decks that can be badass outside cEDH and decks that can pull cEDH strategies similar to those of their more competitive peers, but not with the efficiency it would take for them to be widely considered “competitive”. And Yuriko compared to Edric seems to fit the latter description perfectly.

(Disclaimer; I don’t play cEDH. I keep my ear to the ground and I play as powerful decks as my budget allows. But I don’t have the budget or the people needed to play cEDH regularly. However I did try to build Yuriko and I’ve been playing and studying Edric for about a year. Written up there are my thoughts on the 2 that came up as the result. If my “references” aren’t enough for you, you’re free to ignore everything I wrote. I just wanted to share my 2 cents on something I was asking myself 6 months ago)

I found the secret to a quicker Yuriko deck is top deck manipulation. Here is my package for that: 1x Augury Owl 1x Insidious Dreams 1x Lim-Dul's Vault 1x Mystical Tutor 1x Personal Tutor 1x Sage Owl 1x Sensei's Divining Top 1x Vampiric Tutor

I would definitely swap out your Diabolic Tutor for at least Mystical tutor, and budget depending, the other 2 I listed as well. Maybe Crystal Ball but I find it too slow.

You could also focus the deck more by taking out the graveyard recur. I would also add more 1 cmc unblockables to enable all your ninjustu ninjas. Here's my decklist: It's very focused on what Yuriko wants to do.

This is cool. I dismantled a Grixis deck a while ago, and I've been trying to decide whether I want to build Grixis Rogues with Marchesa, the Black Rose and Oona's Blackguard / Metallic Mimic / Grenzo, Dungeon Warden or to go in on Yuriko with a few of the staples like Insidious Dreams that I traded for when she came out. They both seem like fun.

For this deck, if you plan on repeatedly bouncing Yurkio, Phyrexian Tower is probably as cheap as it's ever going to be, and it can minimize the cost of ninjutsu-ing in every turn. If you get a little deeper on tribal, Cover of Darkness is very good, as is Kindred Discovery . Also, 32 lands is pretty ambitious. Only cEDH decks that don't expect to see turn 6 most of the time run that few lands.

Also, nice tech on Unnatural Selection . I want to build a Saproling deck with Reaper King and subtype changers.

If you want extreme consistency maybe add more tutors. Mystical Tutor and Personal Tutor can find Doomsday . Insidious Dreams is an instant and can find any card(s) you need.

Hi there! My Yuriko, the Tiger's Shadow is part ninja tribal, part topdeck matters, and it is aggresive enough to win turn 5-6 (no infinite combos). Goal of the deck is to show fat cmc cards from the top with Yuriko or other ninjas (or creature type shenanigans) and kill the table with Yuriko's ability.

To kill the table, you need to have 3 triggers and tutor 3 cards. Insidious Dreams is the best way to tutor. Some combination of Lim-Dul's Vault Mystical Tutor Vampiric Tutor Personal Tutor Imperial Seal and Brainstorm Scroll Rack

Note that most of those can and should be played instant speed with yuriko triggers already on the stack. You tutor for: Commit / Memory Temporal Trespass Blinkmoth Infusion Draco Treasure Cruise Draco and Blinkmoth Infusion should go last, unless you go for the win, as they are unplayable. 30 damage to each opp with just 2 triggers is really fun.

Daarkest Here're some of my recommendations:

Vampiric Tutor - Replace with Insidious Dreams . Cost more to cast but still lines up the top of your library at Instant speed.

Expropriate - You can consider Savor the Moment . Skipping the untap step doesn't hurt Yennett, Cryptic Sovereign as she has Vigilance but it'll affect your lands and mana rocks.

Grim Monolith / Mana Crypt - Leaving these out will hurt the tempo a little as they're key pieces for me to power out Yennett very early (Turns 1 - 3). Feel free to throw in any mana rocks in their place. Dark Ritual does provide the 1 time mana boost as well.

Mana Drain - Feel free to replace with any other counterspell of your choice. I'd still try to keep the CMC to 2 or less so we can imprint it on Isochron Scepter when needed.

Scroll Rack - Scroll Rack has 2 functions in this deck.

A) Puts "Bombs" I drawn back on top of the library - Agonizing Memories or Hidden Retreat are possible replacements for this effect.

B) Help filter and rearrange the top of my library - Any cards with Scry effect would work here, e.g. Seer's Lantern .

Which card you select as replacement is up to you and your preferred play style.

Hope this helps. Cheers!

Vampiric Tutor is the #1 card you could put in to improve the deck. Diabolic Vision is an excellent cantrip. Temporal Trespass is the best extra turn spell you could ask for, since the CMC is an upside. Same goes for Curtains' Call and Avatar of Woe . Insidious Dreams and Ancestral Knowledge are extra Doomsdays. Unnatural Selection is an extra creature-type changer. Emrakul, the Promised End is a good eldrazi of choice, since you'll actually be able to cast it if you tutor it to the top of your library. Trench Gorger is a good late game card, since it does triple duty acting as a huge beater, high-CMC target, and deck-thinner. For little guys, Tormented Soul , Triton Shorestalker , Faerie Impostor , Prickly Boggart , Vampire Cutthroat , Looter il-Kor , Nether Traitor , Flitterstep Eidolon , Thalakos Seer , Baleful Strix , Augury Owl , Spire Owl , and Sage Owl are better than some of your choices,

Well, when going for the CMDR kill, Mesmeric Orb is the card of dreams, where other cards aren't bad, like Vicious Rumors, they don't do enough to warrant me wanting their inclusion without the commander.

What should be kept is a lot of tutors, to fetch different cards, as well as a lot of ramp. Then a reasonably large hand disruption package, and finishing the deck off with some combos, and cards that do a ton to swing the board in your favor.

Unsure of your budget, and the power level you want, here are the cards I would add to increase the competitiveness of the deck:

Lands: Ancient Tomb, Gemstone Caverns, Bloodstained Mire, Polluted Delta, Verdant Catacombs, Marsh Flats

(On a budget? Do nothing with the lands!)

Tutors: Demonic Tutor, Imperial Seal, Vampiric Tutor, Grim Tutor, Cruel Tutor, Demonic Consultation.

(On a budget? Mastermind's Acquisition, Diabolic Tutor, Dark Petition, Behold the Beyond, Demonic Collusion, Demonic Consultation, Diabolic Revelation, Increasing Ambition, and Insidious Dreams)

Ramp: Mana Crypt, Mana Vault, Mind Stone, Thought Vessel, Charcoal Diamond, Lotus Petal, Everflowing Chalice, Chrome Mox, Mox Diamond, Coldsteel Heart

(On a budget? Mind Stone, Coldsteel Heart, Charcoal Diamond, Everflowing Chalice, Coalition Relic, Fractured Powerstone, Prismatic Lens, Fractured Powerstone, Thought Vessel)

Draw: Sign in Blood, Night's Whisper, Sensei's Divining Top, Scroll Rack, and Asylum Visitor (can top cards you don't want to discard), Library of Leng (tops cards you don't want to discard again... but in a different way), Necropotence

(On a budget? Sign in Blood, Night's Whisper, Read the Bones, Library of Leng, Asylum Visitor, Necropotence, Ancient Craving)

Stax: Sphere of Resistance, Thorn of Amethyst, Lodestone Golem, Damping Matrix, Chains of Mephistopheles, Trinisphere, Tangle Wire, Smokestack, Pox, Liliana of the Veil

(On a budget? use control elements like Doom Blade, and removal in black instead of stax, some of the more budget stax is okay, but generally the more layered stax the better, so the less the worse each is. Removal is a good replacement.)


Vicious Rumors, Abyssal Nocturnus, Fell Specter, Guul Draz Specter, Herald of Anguish, Hypnotic Specter, Liliana's Reaver, Myojin of Night's Reach, Needle Specter, Scythe Specter, Sewer Nemesis, Stronghold Rats, Wei Night Raiders, Whispering Specter, Ghoulcaller's Bell, Darksteel Plate, Ordeal of Erebos, Raiders' Wake, Bontu's Last Reckoning, Anvil of Bogardan, Putrefaction, Painful Quandary, Megrim, Fraying Omnipotence, Rise of the Dark Realms, Torment of Hailfire, Liliana Vess.

Not sorry about the long comment ;)
