oh man, I'm excited! Couple suggestions for storm:

High Tide and a revision of the mana base to include more islands would be highly advisable. You are going to need more than rituals to keep the gas on during your storm turn. In that vain, Waste Not with the number of wheels you have could be good too. Candelabra of Tawnos is probably a pipe dream but its obviously insane with high tide.

A couple more rituals would go a long way too. You want to hit a nice mix of mana sources and draw spells in order keep hitting the gas until you draw your Mind's Desire, Doomsday or Yawgmoth's Will so you can actually storm off. It will suck having lots of draw in hand, but not enough immediate mana sources to keep going.

Some cuts to consider:

I'd cut Exploration. Your land count is too low for this be good.

I think Paradoxical Outcome could go. It's better in eggs storm, where you have way more artifacts.

Future Sight + helm could go. You rarely need to draw your entire deck with a good amount of draw and wheels, and helm ramps the rest of the table on its own. Keep top, i dont see a down side to running it.

I've run Carpet of Flowers in our meta twice now. Because of the distinct lack of mostly blue mages in our group it has been very underwhelming in karador.

Anyway, best of luck brewing! this looks like quite the list and im excited to play against it :)

Thanks for the suggestion Rex! I've definitely considered Hypergenesis since it can synergize so well with Yidris. But in this Storm-focused build I'm barely running any creatures. Assuming I had a full hand I could drop a pile of mana rocks with it but... that's not going to help my game much. In fact, a lot of those cheap or zero-cost rocks are better off in my hand until I'm ready to Storm up a disaster for my opponents.

Generally, I've tried to steer clear of Suspend cards in this build. They're great if you can Cascade into them, but I suspect I'll be aiming to Storm more than Cascade here. Outside of Cascading into Hypergenesis, having to suspend it from my hand gives away the whole advantage of surprise. Think I'll pass on it for now.

Thanks for the thoughtful critique Handsome_Panda, especially the cuts!

I initially avoided High Tide because of the difficulty in hitting a significant Island count in a 4-colour deck. But this Storm build lends itself to more of a BU land base, so I'll see what I can do to increase the Islands.

Good call on Waste Not, I hadn't thought of capitalizing on the wheel effects' impact to my opponents. I'll have to skip the Candelabra though - I think this deck will be stretching the budget as it is ;)

Adding some red rituals to supplement the black ones.

Agree with your reasons for removing Exploration and Carpet of Flowers. In that vein, I'm also taking out Red Elemental Blast and Pyroblast as their focus is too narrow and less of a sure thing in our meta.

I was thinking Paradoxical Outcome would work well to return all my 0-cost permanents to my hand for cards, then dump them back into play for Storm. But you're right, I may not have enough to make it worthwhile.

I pictured Future Sight as a benefit to kick off my Doomsday piles, but was already concerned about that . Might just axe it.

Helm of Awakening can go.

It's gone.

Forget about it already.

Handsome_Panda I did some rethinking on a couple cards:

• If I'm Storming as intended with 10-20 spells a turn, Helm of Awakening is pretty great.

• Though my land count is low, with the big draws I'm hoping for, being able to drop land at twice the speed seems pretty beneficial. So I'm trying Exploration again.

See, the thing about Storm is that it doesn't have to be your only win-condition. These kinds of decks produce a lot of mana as a side effect in order to work properly, and that effect can be pushed really hard. , , and can produce a lot of mana with the right interactions. For example Mana Geyser with some kind of copy effect can be downright disgusting, and you can never go wrong with Cabal Coffers + Urborg, Tomb of Yawgmoth. You also have Magus of the Coffers and Crypt Ghast for extra . And what to do with all that mana? Comet Storm and/or Exsanguinate. It's not quite a Storm win, but it will make the deck downright ridiculous and versatile.

Aetherflux Reservoir

Voltaic Key

Future Sight

Copy Artifact

Pongify

Pyretic Ritual

Rapid Hybridization

Unsubstantiate

These are the cards that immediately come to mind that you probably don't need if that helps haha. You also might not need Laboratory Maniac.

Scorprix, Lab man is the only win condition after doomsday, don't cut this. I agree with the rest of your cuts.

Romer, Yeah i mean, give it a try right. If your keep Helm, then id say its worth it to keep future sight. It gives you top deck visibility for when you cascade with ydris, plus i mean, in a storm deck, drawing your library usually means you win.

Along the same lines as what Scorprix said, i actually think you have too much removal. I would cut all of the following because for one, they are too narrow, and two you already have better options in the deck:

Slaughter Pact

Rapid Hybridization

Pongify

Abrupt Decay

Dreadbore

Hull Breach

Toxic Deluge

vs the following cards that are far better and wider in terms of what you can actually do with them:

Unsubstantiate

Turnabout

Hurkyl's Recall

Cyclonic Rift

Chain of Vapor

Eventually i would consider Force of Will and Mana Drain added to your counter package, but thats gravy cards, not required id say.

The above can all serve double duty (you do run timespiral and yawgs win after all) as removal and storm enablers. The straight removal is 1 shot kill something... Obviously it has its place, but your playing storm. YOU are the one threatening to end the game every turn, you dont need to worry about pesky combat damage and creatures. My two cents anyway.

Oh last thing. Cut Necropotence. You always tutor for Ad Nauseam if you can when you are ready to hit the gas, and necro will hose you reaaaaaaaallly bad on your yawgz win line of play.

Eye of the Storm

Put your Rituals under it = mana for days

Put your wheel effects under it, draw your deck....Laboratory Maniac or Sphinx's Tutelage

Knowledge Pool + Mind's Desire comboing with the Eye = lolz

Grapeshot or Tendrils of Agony under the Eye is a win con as long as you keep storming...so those rituals and cantrips seem really good im the Eye now ;)

Ahh, I forgot about Doomsday!

Tidespout Tyrant is the cornerstone of lots of combos, but i do feel as if it is unnecessary.

KailDaemon - Eye of the Storm is pretty cute... but its also pretty bad in storm. It costs 7 (!!!) with 2 u, and if you Ad Nauseam into it... well your probably gonna have a bad time. There's a reason competitive storm decks don't run it, its clunky and redundant.

Everyone: Thank you! This is great feedback and is really helping me refine and tweak how this deck plays.

I agree SLP_500, Storm doesn't have to be my only win-con (that's why I like Aetherflux Reservoir!). My hesitation is that I'd have to cut out a fair amount of Storm-related cards to make your suggestion a reliable sub-strategy. Mana Geyser, copy effects, Magus of the Coffers, Crypt Ghast, Comet Storm, Exsanguinate - that's already 6+ cards to make room for, which will weaken how reliably I can Storm off. As it is now, this build is fairly resilient to interference with at least 5 different win-cons: Aetherflux Reservoir, Grapeshot, Tendrils of Agony, Tidespout Tyrant, Laboratory Maniac.

@ Handsome_Panda, I'm probably missing something but I don't get how Necropotence hoses Yawgmoth's Will. Necro only makes me exile cards if I discard them but typically I'd be aiming to cast them, in which case they still land in my graveyard, right? For reference, the serious Storm players seem to run Necropotence.

@ KailDaemon: Eye of the Storm sounds pretty awesome but I hate that I'd be giving all my opponents access to my draw and ritual spells each turn. I generally try to avoid giving my opponents any benefits and am afraid of Ad Nauseam-ing into Eye. I'm not saying no... I'm just still Pondering it. Sphinx's Tutelage is interesting, too. I hadn't thought of it earlier but it makes sense since I'm regularly drawing most of my deck. Does Sphinx's Tutelage work with Ad Nauseam though? I'm not sure if Ad Naus counts as "drawing a card" because the phrasing says to put the card into my hand.

re: Removal

I agree Scorprix and Handsome_Panda, I have too much removal and I appreciate your suggestions of which ones to remove. In the past, I've tended to favor removal over counters and bounce but for this deck I get it. Counter/bounce is better and cheaper and definitely the path forward.

re: Aetherflux Reservoir

Scorprix and Handsome_Panda suggested cutting Aetherflux Reservoir but it seems to synergize really well with Storm. Let's discuss!

If I'm playing standard EDH (starting with 40 life) with one opponent, have Aetherflux Reservoir on the battlefield and play 5 spells in a turn (super easy in this deck), I gain 15 life and go up to 55 life. Pay 50 life, kill my opponent. Nice.

If I play 15 spells in a turn (also possible) with Aetherflux Reservoir already in play, I gain 120 life. If that last spell was a Tendrils of Agony then I deal 30 damage one opponent and gain another 30 life. Now I activate Aetherflux Reservoir 3 times to immediately kill 3 opponents. Seems pretty good.

Love, love this deck! +1. I was brewing up a Yidris deck myself, but I stumbled upon this, so I think I'll just stick with this.

Ad naus doesnt draw...but i only suggest eye if youre going to win with it. Its a powerful end gamer if the turn you cast it you win

Ahh your totally right about Necropotence! My bad, RTFC right?

That math on the reservoir doe... so good. That sounds like a really solid game closer, especially in multiplayer.

might I suggest Young Pyromancer

Romer I see your point now that I've read Aetherflux Reservoir a bit more closely; that's a sick interaction. I mostly just wanted to throw out more options since Storm decks can get hated out after they win once, but you're shooting for a finely tuned deck that can win before that happens. Plus, who couldn't use more mana?!

Much better and personally more fun than the other Yidris deck floating around. If it wasn't so much money I'd easily go and make this. +1

There are more than 100 cards here you know

bedlam reveler.

@Denthrass, Young Pyromancer would definitely synergize with the Storm mechanic, but if this deck is firing properly then his effect is pretty 'win more.' I'm going to pass in order to keep really streamlined towards the Storm path to victory.

@ooop333, Bedlam Reveler's a neat new card. I defs see how he'd benefit from what's going on in this deck but I'm getting really picky about which cards above make the cut. I've got stronger wheel effects already and I can't see myself ever tutoring for this to win me the game.

Yeah Rikeus I was aware that I was over 100 cards. I had the deck set to 'prototype' while I agonized over what to cut to get down to 100. I took my time for a couple weeks while I bought/traded for all the cards I needed to build the deck.

But it's done. No more prototype. I have this. It works. It's glorious.

I like, +1!How tf is it 100% competitive!?

Thanks ACDAMAN!

It's definitely not 100%. They're in the midst of tweaking the competitive algorithm and it's got some issues. Try using the Regen Charts button (on the left) on your own decks - everything's 100% competitive today! :)

Lol thanks, I'm still wondering how they can calculate it.

Generally based on the currently tagged casual and competitive decks on the site. Check out this thread for more details on how it's being calculated and to provide feedback.
