WanderingSpirit on This Deck Has No Win Condition, but Yours Does

Ahh, I remember when Sen Triplets was popular in groups where I live. Still a heavy hitter! Might I suggest Faerie Artisans to clone your opponents' creatures and get artifact triggers, and maybe Knowledge Exploitation for some instant or sorcery fun?

Notorious Throng is janky, but if you want to step you jank up to the next level, give Knowledge Exploitation a try!

Jhoira's never been a commander I enjoy due to the low interaction, but I really like your choice of spells like Knowledge Exploitation to grab your opponents stuff.

Personally, I prefer Kozilek, the Great Distortion for Eldrazi tribal and favor Jodah, Archmage Eternal , Golos, Tireless Pilgrim or Ramos, Dragon Engine for "big mana" decks, due to the more interactive playstyles and access to more colors. Of course, go with what you feel and make your own decisions, there's lots of commander options!

Maybe a good idea would be to make sure your playgroup knows you're not playing cards like Jokulhaups or Obliterate , since the threat of those from a Jhoira deck can make them target you.

Anyway, have fun with it!

You can see them. They are somewhere there. Waiting in their sleep. And when they wake up - they will bring interplanar Chaos and destruction.

Prepare yourselves, though shall they spare no one.

After finding Jhoira of the Ghitu , I was thinking what needs Suspend the most. Obvious answer - high mana cost cards. And what's more expensive, than Eldrazi? Hmm, I have no idea. And that's how the deck has been made. Few cards with "put on the battlefield", like Belbe's Portal or Quicksilver Amulet , few "without paying mana cost", like Omniscience , Sunbird's Invocation or Temporal Aperture and with enough mana rocks Planar Bridge or, of course Eye of Ugin .

Additionally, I like to play someone else's spells, so there is few stealing cards, like: Knowledge Exploitation or Reversal of Fortune .

I have spicied it up with some returning sorceries/instant cards, like Mystic Retrieval or Narset's Reversal .

Of course not to forget draw cards, but it's obvious in blue decks :)

And last and most important part - cards, that are taking off the time counters from suspended cards - imagine card:Omnisciense with Suspend 4 on turn 3 :) And then you have, for example Timecrafting and bang, t4 card:Omnisciense. And if not that, then maybe Ulamog, the Ceaseless Hunger ? And there is more removing time counters, like Clockspinning or Fury Charm or Timebender .

That do you think? Does the deck have a chance?

I am looking forward to see your feedback :)

Thanks a lot MadCatMax! Glad to hear you like the deck. Its so much fun to pilot.

Knowledge Exploitation is spicy tech. My gut tells me that in the right meta, it could do some real work. Especially if you are facing off against an Edric deck chock-full of turn spells.

I'll be the first to admit that Sakashima the Impostor is on the slower end of where the deck wants to be.. It can sometimes provide a burst of triggers to burn out the table, but like you said, often you are already winning at that point. I'm less inclined to run Arcane Adaptation since we have been getting more ninjas printed and it doesn't do anything if the dorks you have out are already ninjas like Universal Automaton and its ilk. Especially in my list, because I run several 0-powered creatures that wouldn't trigger Yuriko even if they connect with an opponent. I do think it could be playable in other lists though. It gets better if you aren't running the Ornithopter squad.

Honestly the best Yuriko deck I have seen

I actually built it but I switched out Sakashima the Impostor with Arcane Adaptation - the impostor only felt good when you are ahead and the arcane adaptation would still give you more Yuriko triggers

I also used Knowledge Exploitation instead of Capture of Jingzhou which actual feels really good and can be a 4cmc extra turn spell and versatile


Spairut on Rogue's Unblockable deck

1 year ago

I think Invisible Stalker is much better than Inkfathom Infiltrator because the stalker has a lot more evasión , not being able to be targeted by any burn spell or removal unless it is a Wrath of God , basically it wont die unless you block with it because you're desperate to survive (you cant block with inkfathom infiltrator).

Slither Blade is better than Prickly Boggart , 1 more thoughtness and is truly unblockable

Maybe Frogtosser Banneret ?

You can try cards with changeling .

You may add something for late game that gets bonuses from tribals decks like Door of Destinies , Coat of Arms , Adaptive Automaton , Metallic Mimic , Stoneforge Masterwork (i think this one is the best because most of your creatures are unblockable and is very fast , and if you add Invisible Stalker it is almost impossible to get rid of it , while the infathom will probably die instantly when you equip the artifact to it)
