Prognostic Sphinx Discussion

TwelveOpossum on Odd Fate

Normally people between 36-40 lands, right? I'd say this one wants 38. Couple especially good ones: Myriad Landscape and Ash Barrens. If you're serious about the token theme, maybe also Westvale Abbey  Flip.

You might also consider these cheap spells: Preordain, Telling Time and Serum Visions. Truth or Tale also seems hilarious, especially with a little politicking.

I really like your choice of a bunch of modal cards (with odd mana costs, obviously) that can do a bunch of different things. I would add a couple more - Righteous Confluence is less popular than the blue and black ones but still pretty good (life sometimes matters a lot in Commander, this gains 15).

I STRONGLY suggest the Scry temples from Theros block. Temple of Silence, Temple of Deceit &Temple of Enlightenment all help you control the top of your deck and your colors. Isolated Watchtower is also pretty freakin good in your deck as green decks will often ramp, so it should often be live.

Some pretty good ones from EDHrec that contribute to your strategy: Prognostic Sphinx, Windreader Sphinx Angel of Serenity Luminate Primordial and especially Conundrum Sphinx Penance and Future Sight. Those last three, I really would try to find room for (holy damn, especially Penance).

Grave Betrayal, Entreat the Angels, Terminus, Overflowing Insight, are good bigbois that work (in different ways) with Yennett.

Then a couple general comments - you should probably try to include 2-3 sweeper effects and maybe 3-5 point removal (for a creature, I mean) effects, and a few effects that hit other permanent types (like Anguished Unmaking and Utter End). I think you'll probably want to include most of the cards I mention above that mention card draw, because it's REAL important to not get stuck on lands in EDH, and card draw's really a good way to avoid that.

A few cards that I think would be good cuts: Dowsing Dagger  Flip, maybe Anointed Procession depending (you probably would want 20-30 token effects to justify this), Aphetto Alchemist, Lich Lord of Unx also because it's expensive, Master Trinketeer which has an activated ability that's way too damn expensive, Retrofitter Foundry which again is way too expensive, Sram's Expertise is probably too low impact - Righteous Confluence would be a great replacement here, for example, Connive / Concoct and Discovery / Dispersal are both a lil underpowered too.

Those are some thoughts for now - looks real fun though, isn't this commander's complexity so nifty?

I think some of the weakest cards are Boreas Charger (few plains), Grip of Phyresis (which is adorable though so I love it), Sphinx of Jwar Isle (even CMC), and Prognostic Sphinx (hasn't seemed useful).

Does anyone know in what order Yennett, Cryptic Sovereign’s, Prognostic Sphinx’s and Aqueous Form’s effects would resolve? Particularly, would you be able to scry and THEN use Yennett’s triggered ability, or would her effect go first, and THEN scry?

Oh Hell Yeah! I love me some ninja tech. I don't quite know what you have planned but don't forget Sakashima's Student although it might hurt the budget. Another card worth looking at, if you can squeeze it in your 50$ budget, is Duplicant because colorless exile on a stick? Yes, please. It's cc allows for some nice burn when ripping it off the top with our commander.

Now for some sweet budget tech. Sandstone Oracle is a flying threat that refills our hand and hits the table for 7 damage off the top of our library. I know Steel Hellkite is a popular budget option to deal with enchantments and artifacts in Grixis but I would give Meteor Golem a try. I find the dragon often eats removal on sight or gets chumped which prevents you from dealing with the problematic permanent you absolutely need to destroy. The golem circumvents all that with it's ETB ability. It's clean and recurrable.

Lim-Dul's Vault, Shadows of the Past, Read the Bones and Cryptic Annelid have a home here. Other interesting options include Mystic Speculation, Darksteel Pendant and Sentinel Totem which doubles as GY hate. Finally I would also consider Prognostic Sphinx, Conundrum Sphinx and Arbiter of the Ideal.

Anyway man. I'm looking forward to the build and video!

If you win by milling, then why include cards like Prognostic Sphinx or Slither Blade.

As a matter of fact, after playing around with the deck for a while I have been thinking about taking out the both Jace, Unraveler of Secrets and the two Dovin Baans (they seem to only work as draw engines that die after a few turns, for me at least) and I definitely see how Jace, Architect of Thought would work much better in this deck.


Unfortunately, I usually find Geist of Saint Traft to be a bit fragile and prefer creatures with more evasion (unblockable, flying), larger bodies (at least 5 usually), or ways evade removal (manlands and indestructible). As for Dragonlord Ojutai... it looks like a much better version of Prognostic Sphinx and I'll definitly consider it, but my original plan was to swap in a couple Torrential Gearhulks and maybe some Snapcaster Mages as soon as I got my hands on a few copies of Cryptic Command. And lastly! I've already been thinking of swapping out my current planeswalkers, and all three of the abilities on Gideon of the Trials line up with what I want my deck to do!

Basic stuff: Land based ramp is more reliable than mana dorks. Many opponents bring sweepers like Pyroclasm in the sideboard, and that shuts you right out of the game. So, I'd suggest exchanging Birds of Paradise for Search for Tomorrow. It costs you one mana in turn 2, but that's it. If you absolutely want to use creatures for ramping, you could go with Arbor Elf, and its best friends Utopia Sprawl and Garruk Wildspeaker. Kiora, Master of the Depths can do a decent impression of garruk in untapping stuff, but you'll really miss the beast tokens.

You need more lands. Playing an extra mana source every turn, and not hitting your land drops, just feels bad - you'll have the same mana as your opponent who only plays lands as manasources, but you have to do a lot more for it. If you want to play creatures at 6+ mana, you'll need something 25 lands, maybe 26.

Prognostic Sphinx looks a bit underpowered. When you play something at that cost, you want it to be a real threat. Maybe titans instead - Frost Titan and Primeval Titan?
