Hey Chainedbygod567 thanks for stopping by, appreciate the upvote and question.

The reason I didn't include Mox Opal is because it's a legendary artifact, which means we wouldn't be able to make multiple copies of it with Osgir's ability.

To be more specific: Lunar Necklace, Ashlands, and Mox Moonstone are all "too good" to exist in EDH, imo. We already have Ancient Tomb, City of Traitors, Crystal Vein, Mox Diamond, Mox Opal, Grim Monolith, Sol Ring, Basalt Monolith, and the plethora of good-but-not-great rocks; the problem with trying to push colorless is that you inadvertantly push all the other colors at the same time.

For it to be more balanced, you'd need some sort of clause that prevented use on colored spells, in colored decks, etc.

Profet93 .. A lot to unpack here and its late but I want to respond before I forget.

Maralen of the Mornsong, It would just be another option to lock the game when I am ahead. I do not currently have the card though and I am loathe to spend $20 on a card that might just sit in my binder. This will only be tested if I can trade for one.

Mox Opal I agree. I do have a bit of artifacts in my deck and I do consistently have the extra 2 needed to trigger metalcraft. The chance it is a dead card though in the early game could cost me the game itself. Like the Maralen, unless I can trade for it to test it out I am not willing to drop more $ on a possible binder card.

Karn, the Great Creator I do like him as a stax piece just in my current game environment the only consistent thing it is turning off are mana rocks, which to me is less impactful then what else I could be using the 4 drop on. If it does change I can see him being a good add. I have Karn though so it might be worth testing out.

Cabal Coffers + Deserted Temple + Rings of Brighthearth = GG. This might be worth adding as another win condition. I didnt add one of these win conditions before because I didn't want to add cards that had no use on their own. I am worried that Rings is slow.

Opposition Agent + Wishclaw Talisman. Ya I knew about this. I like wishclaw as a 1 mana tutor to finish up the game. It replaced Grim Tutor, it was a little to slow.

Bitterblossom + Contamination The times I have had it out on the board it has done very well. It has shut off my own Coffers before but the lock was enough. I have also used it just to slow them down a couple turns and let it sac itself. It is not perfect but it helps me break parody and get ahead.

Crucible of Worlds in this deck I am not fond of it. It takes a valuable 3 drop spot and has no impact when coming in. It does look better if I had the 5 sac lands to go with it, but its still a hard sell for me.

Bloodstained Mire Marsh Flats Polluted Delta Prismatic Vista Verdant Catacombs, I would like to get these in the deck I just do not currently own any so its a $$ thing.

Urza's Saga has done well so far. It gives me early gave protection with constructs if needed and a direct line to artifact mana or in some cases more importantly Sensei's Divining Top

This is a 3am response so I hope I didn't butcher it to much. TYVM for the insights though, its all worth trying and seeing what happens.

Spirits on Yuriko, Shadow of Fate EDH

2 months ago

Wow thanks Virlym!!!

Agreed Thrasios, Triton Hero or a Kess, Dissident Mage way more value for Fish-Consul, was hoping for some flavor, along with the easiest win in commander today. Goal is to build a fun, rogue style deck, but that I can play in High power format games, 8+. I'll think on the fish overnight, certainly is powerful (and lots of interaction in the format to deal with it, a couple you identified). Doomsday without fish wouldn't be good either, too much work and weird cards would have to be put in without it. I defintely want a focused strategy not just play stuff for needing to play it.

Agreed Mana Vault is wrong, not on curve, going to replace that one with something. Dark Ritual I think I might need, a T1 Opposition Agent or Nashi, Moon Sage's Scion, maybe an Arcane Signet into an Unblockable with a Sensei's Divining Top lots of scenarios I can see using that {b}{b}{b} Dauthi Voidwalker that grabs me a fetchland I can use to not miss my T3 land drop, etc.

For Mox Opal I haven't done an analysis "yet", i have calculated the hypergeometric probabilities and charted them, see Kaalia Deck, but it's generally low, even lower with no Mana Vault.

The land selection supports the Thassa's Oracle + Tainted Pact, if you have any duplicate cads (including basic lands) then Tainted Pact doesn't work as a Tutor or a win enabler. I included the basic & it's snow-covered counterpart for maximum coverage there. I'm prioritizing lands that 1) Never enter tapped, 2) are T1 useable lands. Spire of Industry might not be right, similar argument to Mox Opal what is it's activation probability. Could go back to Tarnished Citadel or Ancient Tomb maybe? I dont like the colorless, or maybe just an Island like Cephalid Coliseum. I've tried finding another dual colored land that meets the criteria but can't which is why I landed on Spire of Industry. If I abandon fish-pact, can add more basics.

Satoru Umezawa I had a hard time. His CMC4 activated ability is useless, I was more evaluating on the following 1) Whenever Yuriko, the Tiger's Shadow commander ninjitsu, I get to a) Look at the top 3 cards of library, b) Choose one for my hand (a counterspell or land or something), c) was a ninja lol. Looking again, his ability isn't a "may" so he's actually going to break the sorcery speed top deck manipulators like Imperial Seal or Personal Tutor, so he's bad, needs to come out, the draw isn't worth disrupting the synergy of the deck.

Viscera Seer has goldfished ok with me so far, why i've liked him a) He is CMC 1, so could be an early swing unblocked to commander ninjitsu and doesn't cost much to recast, b) He can put Yuriko, the Tiger's Shadow back into the command zone, so that she can commander ninjitsu in "unblockable" again, dont want her stuck on the board with no way to attack, c) The top deck manipulation helps drawing what you need when you need it or getting rid of a card so that you can connect with a bigger spell. He also protects my stuff from exile effects, or effects that might turn her into an indestructible insect or a land or whatever all those things want to do! d) Can block and sac against lifelink (if that matters, probably not), not giving their footing back when I'm trying to kill with my Yuriko ability. He's not critical value, but having a way to consistently cast that unblockable, commander ninjitsu, replay the unblockable and get Yuriko back in command zone, is good isn't it? Cunning Evasion dpes this for all ninjas where Viscera Seer only works with Yuriko.

Praetor's Grasp probably wrong. Reevaluating there thanks.

I don't like that Grazilaxx, Illithid Scholar only triggers once, thought he was for each creature. Hmm. If unblocked draw a card. If blocked return to hand vs. if blocked return to hand. Grazilaxx, Illithid Scholar gives them additional incentive to block, but not much more, it's an extra card per turn, with the unblockables it should be anyway, so like a Phyrexian Arena with a second ability? Easier to remove. Cunning Evasion really just de-incentifies the block, especially if Yuriko on the field, but most stuff is unblockable or will draw a card. So point taken, is the extra card here or there worth the extra mana, and making it easier to remove, hmm. Maybe both are good?

Opposition Agent agent certainly is good stuff, but it has so many benefits a) It's a CMC3 instant speed tutor (for a land, any card, multiple lands, etc). It's going to get you something you want b) It's an essential stax piece, the higher power you get, the more value he is, essentially it stax locks down oppoents lands (too many fetches not enough basics the higher you get), finding an answer to you board (no looking for a board wipe for your ninjas (high power usually have 1 or 2 and rely on tutors to find it when needed), or even looking for an answer to Yuriko. Opponents durtle under Opposition Agent unless they have a removal "in hand" forces them to draw into a solutions, under a restricted mana base, decks playing 10-20 tutors shuts down 20% of their deck, slows them down etc. Until they ban this card that should never have been printed, or at least printed in White instead, have to play him. In Mid>High games or lower, he's far less useful as you see more basic lands, or more enters tapped, more draw effects and fewer tutors understandably.

This is really fantastic discussions, appreciate it, hopefully not consuming too much of your time :)

Thousand-Faced Shadow, I got hyper focused on his CMC4 ninjitsu for a "lack luster" ability and didn't even consider he's a CMC1 with flying evasion built in, that's also a ninja! Who cares about his dumb ability! He's going in 100%.

Mist-Syndicate Naga he's really just a 3/1 for 3 (bad), no evasion (bad), ninjitsu is CMC3 (bad, why not CMC1?). He replicates and then exponentially populates, but you can't bounce the copies to hand to protect them, and as with exponential growth, it's the T1-3 growth that kills you, the game isn't going to go long enough for him to deliver the value he could, let's say on T14 of a game, his T4 swinging. It's extra draw, but how is this guy getting through all these times to draw the cards, and why would I even Ninjitsu him lol. Can't get there on this guy.

Moon-Circuit Hacker and Ninja of the Deep Hours I keep thinking about though, their Ninjitsu costs are reasonable, but can't decide what they take the place of, a control card? a tutor card? That tutor finds me a win-con piece, a big spell for Yuriko to hit with, or a Ninja that delivers more advantage. However, if Yuriko is offline for whatever reason, they can draw into a solution themselves. In reconsidering mode on those. Thought I was close to having the list, your points have made me reconsider so many things.

The other low-cost ninjitsu are a little too situational and for like Mid>High games where board state matters more. The higher you get, the less important a board state is, and other than disrupting 1 player at sorcery speed (since Ninjitsu is on your turn, during attack, and only unblocked) it's utility is low. If the games are 5-7 power level, things tend to come out, wait around a turn before they do their thing in 7+ "usually" the thing comes out and it's already done it's thing Dockside Extortionist or a creature with haste that activates, etc. There are some exceptions like an Esper Sentinel or something, but in general Destroy/bounce are usually bad, want Exile at instant speed to have more "interaction".

Doomsday isn't really necessary, it's just an easy T1 win-con that tutors all the cards in combo. I haven't figured the stack but probably 1BBBB (5CMC T1 win), 1BB with a dark ritual. I'll build the stacks but that seems right. T2 win with lots like Lotus Petal, Chrome Mox. I'm just not 100% sold if it's needed and also means can cut Plunge into Darkness as well, although I think Night's Whisper would still stay even without Doomsday. Fish-consul is UUB T1 or Fish-pact 1UUB, so there are more efficent lines than Doomsday. There is a BBB Doomsday win-line but too many cards that don't synergize well with the commander in the deck.

Thanks so much, a bunch more modifications to the decklist coming tonight! Was extremely helpful.

Virlym on Yuriko, Shadow of Fate EDH

2 months ago

Honestly, I wouldn't bother with the Thassa's Oracle line. There's much better generals out there for it over Yuriko, the Tiger's Shadow (like any Thrasios, Triton Hero deck partnered with something that has black in it). Doomsday could still work with Yuriko, the Tiger's Shadow as a game ender tho if you really wanted to keep that in. It's really your call, but I never liked setting myself up to lose if something gets countered (Trickbind makes you lose to the Thassa's Oracle line, and something like Angel's Grace will make you lose to the Doomsday line). Having said that, the following will assume you are focusing on Yuriko, the Tiger's Shadow, and not a planted "good-stuff" strategy.

glaring issues in a general sense from your list :
1)You have poor ramp choices for Yuriko, the Tiger's Shadow
2)Your land base is too awkward and has unnecessary things in it.
3)You have some turtle cards that don't really have much use in Yuriko, the Tiger's Shadow

1)Mana Vault is more for a deck that wants big explosive turns, not ramp for small things over multiple turns. You are hardly ever going to want to dump 4 mana into untapping it. Same concept applies to Dark Ritual as well, especially considering it only gives you black mana. Lotus Petal falls into this category as well to an extent. You don't want explosive turns, you want consistent pressure. Mox Opal makes you life more complicated for a potential free mana, which leads into the next issue.

2)Your land choice is too awkward. You have artifact lands to turn on Mox Opal, but they serve no other purpose and can be wiped out with artifact removal. If you are running so many different lands, you generally want to be taking advantage of something where that matters (like Field of the Dead, and you usually want to avoid using the non-indestructible artifact lands unless you have a lot of artifact synergies. They are too vulnerable to just have for 1 or 2 cards. You have more fetch lands than you have targets for those fetches. You have 3 black fetchs, 3 blue fetches, 1 black/blue fetch, and 1 basic land fetch. You only have 4 basic lands, and 2 fetchable dual lands (giving you 8 fetches for 6 targets). Spire of Industry is honestly too reliant on other things that it can basically be counted as a colorless land with no utility.

3)Satoru Umezawa is cute, but doesn't help in a Yuriko, the Tiger's Shadow. It's main purpose is to cheat in big things for 4 mana. Anything you have over 4 mana should already have a ninjutsu reduction to that. Spellseeker is only good for the Thassa's Oracle line and has no real impact with Yuriko, the Tiger's Shadow aside from tutoring for a tutor, which is awkward (Solve the Equation follows the same line of thought). Viscera Seer's scry ability may seem decent to try and find something for Yuriko, the Tiger's Shadow, but you would need to sac ninjas or enablers, which would lower the amount of triggers you would get. The only real payoff for it is if you're trying to win that turn and you sac your ninjas after they trigger Yuriko, the Tiger's Shadow. Praetor's Grasp is too reliant on your opponent having something useful to you, and isn't reliable enough for what Yuriko, the Tiger's Shadow wants to be doing. And if you're using it to remove you opponent's wincons from their deck, you might as well just use something like Extract for that as it's cheaper, or Sadistic Sacrament as it will hit more targets. Grazilaxx, Illithid Scholar is a little too fragile for the bounce it gives and you would be better off running Cunning Evasion. The card draw on it really isn't necessary. Yuriko, the Tiger's Shadow tends to give you more cards than you need, you don't need additional card draw reliant on damage. Opposition Agent kinda just falls under the "good-stuff" category and will most likely have a prompt death by any1 after you get a land off it, otherwise if kinda just sits in your hand and people will assume it's just a counter.

Ninjas of note that aren't included: Thousand-Faced Shadow, get it, it's too good. 1 drop flier is an enabler spot, but it is also a ninja. Later on, it can be used to double up some ninja triggers as a toolbox card. Mist-Syndicate Naga, expanding your ninja army is really nice and forces value from your opponents to deal with the growing threats. Moon-Circuit Hacker / Ninja of the Deep Hours, extra card draw on cards ninjas with low ninjutsu costs.

Some more meta call ninjas: Throat Slitter / Dokuchi Silencer, removal is nice, especially when it's already lending towards what you already want to be doing and not taking up additional space. Mistblade Shinobi temp creature removal, can set people back a turn if you hit something big, has a tap effect, etc. Skullsnatcher, graveyard hate.

Housegheist Spirit-Sister's Call is too slow unfortunately. At 5-mana with a sac-stipulation, only getting one creature back per turn isn't great. It also requires we already have creatures in the yard. It might be fine in grindy metas, but it's not fast enough for our current gameplan.

Foster_I_Am I'd say Dark Ritual, Mox Diamond, and Mind Stone are the best of these acceleration cards. They can help you out if your meta is very fast and you find yourself needing even more early ramp. The reason I don't play rituals and Mana Vault is because they have an opportunity cost of denying us card advantage when games get grindier, which they more often can in casual metas. Commander's Sphere and Chromatic Lantern are too slow at 3 mana, and Jeweled Lotus finds less value in our deck since Teysa is not a great early/accelerated play. It's also a dead draw if we already have Teysa out. Mox Diamond however, if you can afford it, is probably worth it. I don't play it here since it's very expensive and won't improve the deck's power by very much, but if you want to buy one/already have one, it's correct to play it.

kirbysan I agree with most everything you said. Chrome Mox is a great card that I've had in at various times. My desire to play it and Mox Diamond goes up or down depending on how fast/grindy my meta is at any given time. I might put it/them in again soon. I don't think we have enough artifacts for Mox Opal to be good. If we played more cheap stax pieces and other 0-mana artifacts, opal would fit, but right now it seems too situational. Mox Amber seems even more situational as we don't play very mana legendary creatures, especially not cheap ones. Not being able to play it until after we spend 4 mana on Teysa kinda defeats the purpose of being a fast and free mana rock.

Foster_I_Am I think Dark Ritual, Mana Vault, Jeweled Lotus fall into a one-off explosive category which may be useful if you're going to combo off and win that turn. However, early game they're not as strong as the incremental ramp we get from other mana rocks. I don't think Mind Stone and Commander's Sphere are good enough as it's 2CMC for colorless and 3 for color. Chromatic Lantern is useful for color fixing but when running 2 colors I don't see it as a big issue unless you're trying to get Necropotence out early but even then I don't have that issue. I like Mox Diamond except for the price tag and early game you sometimes need that land, but 0 cost mana rocks are my jam. I'm personally going to experiment with Chrome Mox and Mox Opal, possibly Mox Amber. They all have their specific drawbacks but we have cheap stuff to pitch to Chrome Mox, if you're running more artifact ramp then Mox Opal conditions will be easier to hit. Mox Amber will likely be the most difficult to get off regularly as we have so few legendaries.

FireHawk828 on Affinity for Artifacts

3 months ago

I'm currently working on updating my Affinity deck atm. I would suggest exchanging Divination with Thought Monitor as you can draw 2 cards for 1 blue and have a 2/2 flyer which is a very useful blocker or attacker with Cranial Plating. I would also recommend Exchanging the Basic Lands for there artifact Variants, should give a nice boost to the artifact count. a Mox Opal would also be a very useful 0 mana drop even if its just to add to the artifact count to start with. Tolarian Academy is also nice but it can be a bit Pricy and might not be legal in the format you play (me and my freinds play EDH or 60 cards vintage restriction).
