The focus of this deck is to get as much value out of Yidris and multiple cascades as possible. Unlike many of the other decks I've seen online, I've elected to focus more on an aggro approach rather than a Storm approach and only time will tell if this was a wise move.

Since it's initial inception the deck has actually evolved and changed a fair bit. While it's still being fleshed out, the deck is moving in a direction I feel better about and has a smoother and more consistent focus.

As I had previously mentioned, the main theme of the deck is multiple cascades via combat. To achieve this, I've incorporated the following:

Aggravated Assault
Seize the Day
Savage Beating
World at War
Hellkite Charger
Scourge of the Throne

These cards are the main engine that fuels Yidris' fury to its maximum potential. We can accomplish infinite combat phases through the use of cards like:

Bear Umbra
Nature's Will
Sword of Feast and Famine
Savage Ventmaw

Infinite combat means we could conceivably have a near infinite amount of cascade triggers stacking through Yidris. Cards like Fireshrieker and Rage Reflection only further the cause.

So how do we ensure we cascade into the cards we want/need at any given moment? Scrying and general top of deck manipulation help smooth out our cascades into the right sort of pain we need to bring. These cards include:

Thassa, God of the Sea
Sensei's Divining Top
Scroll Rack
Lim-Dul's Vault
Courser of Kruphix
Oracle of Mul Daya
Momir Vig, Simic Visionary
Temple of Epiphany
Temple of Malady
Temple of Mystery

These cards help smooth out the top of our deck to ensure our cascade triggers are used to the fullest. We also run a small tutor package in case we need a certain response ASAP.

Beseech the Queen
Demonic Tutor
Vampiric Tutor
Mystical Tutor
Worldly Tutor

The latter three tutors are nice since they put cards on top of our deck to cascade into while Beseech the Queen can cost 3 mana but counts as CMC 6 allowing for bigger cascade targets. The ability to cast high CMC cards for cheap helps make Yidris' ability all the better. These cards include:

Blasphemous Act
Dig Through Time
Treasure Cruise

To fuel all of these high CMC cards, I've added in a fair amount of ramp to the deck to ensure when Yidris is taken out, we still get there on curve.

Rattleclaw Mystic
Wood Elves
Solemn Simulacrum
Birds of Paradise
Coiling Oracle
Unexpected Results
Skyshroud Claim
Sol Ring
Chromatic Lantern
Darksteel Ingot

Lastly, the deck generates a fair amount of card advantage beyond our Commander's ability. This achieved in a few different ways. Classic draw engines include:

Sylvan Library
Phyrexian Arena
Rhystic Study
Bloodgift Demon

Then we have advantage generated from either my spell casting or my opponents':

Kraum, Ludevic's Opus
Vial Smasher the Fierce
Jori En, Ruin Diver
Mind's Dilation
Keranos, God of Storms
Gonti, Lord of Luxury
Maelstrom Wanderer
Rashmi, Eternities Crafter

Lastly, we have a couple of cards to ensure we get value from the graveyard:

Eternal Witness
Tasigur, the Golden Fang

All in all the deck seems fun and solid. I'm not sure where it would fall into the Tier system in its present state but I'm happy with the deck for the most part. A few cards may still be coming/going.

Let me know what you think. What do you like about the deck? What would you take out and why? As always, +1's are also welcome!

Happy Cascading!


With Aether Revolt coming fast, it's time to evaluate new cards to support Yidris.

Rishkar's Expertise seems like a card that would be amazing in this deck as it has a high CMC for a solid Cascade target and allows me to play another card for free. If Yidris has gotten his trigger for the turn, the Expertise is now 4 spells. A very powerful tempo swing indeed.

Baral's Expertise is also quite nice as a tempo swing and strongly on my radar as well. I am less satisfied in what Kari Zev's Expertise and Yahenni's Expertise offer me but I'm still not ruling either out yet simply for the possibility of getting so many spells cast off a single card

Treasure Keeper is a nice 4 mana card that allows me to essentially cascade upon its death. If I can cascade off of it's casting too, it's another powerful swing in card advantage.

Paradox Engine fits better in a Storm style Yidris deck but it can still be of some benefit to have Yidris and other key cards untap before or after a cascade.

Lastly, Lightning Runner is on the list as another source of infinite combat. While much less reliable than my other sources, it is still on my radar nonetheless.

Let me know what you think. What would you add? What would you take out? Am I missing any new cards worth considering?

This is super awesome. I think you have your bases covered pretty well. I like that cascade is making a comeback.

I love this deck. It is the pinnacle of destruction on the field good job. However I dislike the include of Combustible Gearhulk and maybe you could try Inferno Titan

Thank you Berrin7 and The_2ndpanda for your kind words of support. I'm still playing around with some ideas for the deck but I'm glad you enjoy it in its early phases.

Happy Cascading to you Both!

Like the deck! Just a quick note that Panharmonicon does not work with Maelstrom Wanderer.

I love this... it's given me some great Ideas for my Yidris deck. I've been getting decent mileage out of Sunken Hope too, recasting Maelstrom Wanderer Every turn is nice... and with the help of Animar, Soul of Elements it's even better.

I really like what you're doing here and am planning on building this list with a few nerf's/changes to a little less pure combo and a little more 'goodstuffy.'

With the number of spells you're casting every turn I think it's a mistake to not run Aetherflux Reservoir since the card can just win you games out of nowhere.

In the Vein of ramp, I think it's very worth running the Burgeoning you get in the deck, along with maybe Exploration, and Signets which Iv'e found invaluable in these 4 col decks.

I'd also maybe consider adding back in Bloodbraid Elf, because relevant body and another source of cascade. If you have the money I'm sure an Ancestral Vision could also make an appearance as more card draw to fuel the deck is great.

One other potential change I think bears mentioning, is the addition of either Kozilek, Butcher of Truth , Ulamog, the Infinite Gyre or Elixir of Immortality Since the deck casts so many cards, free ways of shuffling them back in are worth looking at to basically reset the game and go from there.

Just my two cents, I love the deck and am going to have a bunch of fun tinkering with it.

Wizno says... #13

That's a very fun card that I had not known about, SPACEgun so thank you for bringing that to my attention!

A lot of solid suggestions as well NiceThings! After getting in a lot of games with the deck, I think adding back in some of those pre-con cards is looking more appealing.

Wizno Glad to hear you like my suggestions. I like you've got a really solid deck here, and I'm looking to balance it out between having ways to end the game with combo, AND being a very goodstuff deck, because I feel Yidris especially being both 4 colors AND based around Cascade lends itself well to a goodstuff shell.

I realize because of this you may be less interested in what I'm removing but if you'll indulge me.


Scourge of the ThroneWorld at WarTwo of the untap cards, I feel like if you're going for the combo these are fine since they get you there quicker, but in the build I feel like putting together, I'm happier with just the ones which end the game. I could be wrong, feel free to disagree.

Panharmonicon I liked your reasoning for adding it, but I feel like 6 cards out of 99 isn't enough reason to run something that doesn't end the game, It's good for sure but unless your deck is built around it. It'll sit on the battlefield doing nothing and paint a huge target on you, since people expect it to do some random broken things.

Darksteel Ingot

Rattleclaw Mystic and Birds of ParadiseThis is just my own personal opinion but outside of elves, I really don't like creature based ramp, seing as it get's accidentally killed by everything.

Unexpected Results

Gonti, Lord of Luxury

Vial Smasher the FierceI'm probably wrong about vial smasher, HOWEVER, I think she doesn't do enough. This deck seems like the kind that doesn't want to be a target, until it ends the game, Vial Smasher is free damage yes, but you're already so consistent in comboing, is it worth adding in a few points of damage, AND painting a massive target on your back.

Xenagos, God of Revels

Bloodgift Demon This could easily be Phyrexian Arena the two are basically interchangeable. Bloodgift can deal combat damage but costs more, and arena can be cascaded into easier, and is more difficult to interact with.

City of Brass

Mind's Dilation You already have plenty of you do a thing for free, adding a symmetrical effect that's so powerful seems counter intuitive


Aetherflux ReservoirBloodbraid Elf

Exploration or Burgeoning You can fun both, but if you had to pick between them, I'd say it's Burgeoning, since at it's worst it's exploration on their turns for you, and at it's best you drop 4 lands in a turn cycle

Ancestral Vision

Kozilek, Butcher of Truth

Mystic Confluence Since you're a cascade deck counterspells are risky. Confluence is one of the low risk high reward spells that do well with cascade. Could also be Cryptic Command but I like confluence more.

Rishkar's Expertise DO YOU LIKE DRAWING CARDS? I LIKE DRAWING CARDS. Could also Easily be Baral's Expertise depending on what the deck want's more

Some number of Signets, I personally er on the side of playing ALL the ones you can but I could be wrong, just so you don't have to look it up I'll list your choices bellow.

Golgari Signet

Simic Signet

Dimir Signet

Izzet Signet

Rakdos Signet

Gruul Signet

Since Green is your primary color, I'd prioritize Golgari, Simic, Gruul, and then Izzet, Rakdos, Personally my split would be

Simic, Gruul, Izzet, Rakdos.

Hope you like where I'm coming from. I know I'm diluting the combo, but this is just how I'd build Yidris, I think you've got something great here though.

One other addition is Seasons Past

Reason being, card is super strong and you have a lot of varied cmc in the deck, getting back 3-4 cards is worth, Remember it's a sort of combo with Mystical Tutor
