The main goal of the deck is to cast Consultation/Tainted Pact, exile your entire deck, and then draw a card with either Labman or Jace on the battlefield. Since the deck has access to both Tainted and Consultation--and now that there's Jace and Labman--no other win cons are needed as you're safe from Praetor's Grasps or other exile effects. The reason to play Yidris as opposed to Kess in a shell like this is: you don't sacrifice anything in your manabase to play Tainted Pact, you get to play green ramp effects and the awesome green enchantments, and Yidris is a must deal with threat who allows you to keep ramp heavy hands, as opposed to Kess who wants a hand with a little bit of everything. There's also the fact that Yidris' Mind's Desires will be better as he has some powerful 0 mana cards and a more powerful rituals than other storm decks.

I probably do not want another Autumn's Veil card. I don't like City of Solitude because it costs more mana than Defense Grid while costing a colored mana, which can be the difference between casting an important spell and not. It feels like you must cast it a turn before, and that's never a good thing to do. The early Yidris decks just aren't that good. There are decks doing the speed game plan faster than you with more protection than you. Yidris' power comes from how diverse his threats are; you have Labman wins, manual storm wins, and then you have a massive threat in the command zone. The Ogre's potency comes from the fact that his ability is random, so it's easy for people to write it off and kill something like Gitrog or Zur, but if you build your deck totally around him that rational goes out the window and he becomes a lightning rod, making your games come down to turn order (do I get the first turn with my commander or does the Gitrog player). My advocacy for storm in CEDH comes from how potent it is despite its appearance(at all stages of the game). It's really difficult to assess a storm board. If your deck is built to play Yidris fast, you're not only removing your ability to be a surprise (plus the inconsistency of cascade).

Hope this helped. Happy Storming.

@ FurFur I haven't found much need for a second copy of a veil effect either when playing this type of deck, but I figured t was a question worth asking.

As far as Yidris decks in general I don't feel like they are ultimately that competitive in the meta regardless of how they are constructed. The slower style game plans are outclassed by the partner commanders in the same colors who simply do that game plan significantly better and the speedy style versions can indeed come down to turn order. Honestly neither option is all that ideal against high level competition but the deck is fun to play against other tier 2 and 3 cEDH strategies from time to time so I keep it around.

The whole deal with the cEDH meta at the moment is that it only has one truly dominant strategy and this strategy outright demolishes every other competing strategy on a consistent basis. Most of the cEDH community still thinks decks like Flash Hulk or Food Chain or Chain Veil Teferi or Gitrog are high quality decks but these glass cannon strategies get obliterated by the Inception style strategies that are even more consistent and fast about employing a counter to these styles. Yidris decks have the same typical failings and is often put onto the fast Yidris cascade storm plan against Inception style strats anyways so it hasn't made much sense except to play it as a fast style deck that hopes for the best with turn order when that's generally the only way it can win anyways.

And what strategy is that

@ FurFur This one: Inception! (aka Thrymception) [cEDH Primer]. Any UBx shell is capable of running the concept but it mostly revolves around being able to consistently disable fast glass cannon combo decks reliably and consistently on turns 1 and 2 while being significantly more consistent than them overall, more interactive, better at grinding, and equally fast if need be. The only legitimately competitive matchup these Inception style decks face after 500 some odd games of testing is Najeela and even that isn't exactly all that competitive with it.
