Hey this is quite similar to my DD storm Kess list some suggestions I have. Misdirection is pretty high CMC for Ad Nauseam you could probably cut that. Some ad naus decks dont even run Force of Will but I think that is stupid. Faithless Looting isnt as good as some other draw spells, Night's Whisper or Chart A Course would both probably be better choices for your Doomsday piles. Phyrexian Metamorph is also very high mana costed for an Ad Nauseam deck, maybe think about Copy Artifact. Now Paradox Engine is interesting but I really haven't found it to be necessary for Kess decks specifically, between Yawgmoth's Will, the black rituals, High Tide and Kess herself you dont need Paradox Engine for more mana. Its just excessive. Other than that the deck looks pretty good I would add a few more Islands and probably cut Cavern of Souls and Cephalid Coliseum at least maybe some of the orchards too. Mizzix's Mastery, Thought Vessel and Fabricate all seem like iffy choices but they are fine if you don't have other cards.

Here is my kess deck if you would like to check it out. Kess Doomsday Storm

that link doesnt actually take you to my deck this is my deck, Kess Doomsday Storm

Sgtpopnfreash First of all, thanks a lot for your comments!

I don't actually have Timetwister, Candelabra of Tawnos, Flusterstorm, Copy Artifact, Volcanic Island, Underground Sea and The Tabernacle at Pendrell Vale, but if I had them, I would certainly use them in this deck.

Misdirection is a card i'm considering cutting for a while, and Flusterstorm would certainly replace it perfectly.

Phyrexian Metamorph is my replacement for Copy Artifact, but is another card that I always consider cutting it.

I'll tell you why I like having Faithless Looting in my deck. 1) it enables me to trade three(including itself) cards from my hand for two new other cards, while discarding lands or cards that i'll be able to cast later with Kess, dissident mage , such as Mind's Desire, 2) It interacts well in some Doomsday piles that I like to settle sometimes, 3) It helps me to trigger Threshold for Cabal Ritual. Cephalid Coliseum have a similar effect enabling me to trade three cards from my hand for three new cards, while it enters untapped and taps for blue mana.

Cavern of Souls and Thought Vesselare cards that I can probably replace as well.

Mizzix's Mastery and Paradox Engine are too powerful for not to use them. With Paradox Engine on the field I can easely storm out and with a tutor or enough draws I can quickly close the game. It also helps me to avoid some stax effects, which my playgroup is consistently improving. I'm also considering adding Vandalblast or By Force to deal with tax and stax artifacts.

I describe my deck as a combo deck because my main wincon is Isochron Scepter + Dramatic Reversal, which is why I use cards like Fabricate and Tezzeret the Seeker .

Please let me know your thoughts on my comment.

I also do not posses a Timetwister or Candelabra of Tawnos though I really wish I did. As for Faithless Looting all the things you listed are true however it is 2 cards for 3 and generally unless your playing re-animator people run other options, however it is totally a very good 1 drop in red and if its been working for you then by all means continue to use it. I think that changing Phyrexian Metamorph and Misdirection into the stated cards would be the strongest change you could make to the deck. Now Paradox Engine can be very powerful but I do think that By Force and Vandalblast are better at getting out from under stacks pieces than it is. Also traditionally these grixis storm decks are very slim and run off of High Tide and Ad Nauseam pretty much exclusively as to get as much value form them as possible. Paradox Engine doesn't synergize with either of those cards. With Kess, Dissident Mage you should be attempting to cast High Tide twice in a turn more than you should be trying to get a Paradox Engine out. If you do this add more islands.

Sgtpopnfreash I have made some changes in the deck with some new cards i've bought: Imperial Seal,Grim Monolith;Copy Artifact.

I understood what i've said about High Tide, but as i don't have all the good islands (old dual), i see High Tide more like a ritual than win condition. Paradox Engine on the other hand hurts in Ad Nauseam, however it has proven its value for getting me to storm faster and getting out of stax locks such as taxes and etb tapped.

I Know it is kind of win more, however its consistency and power make me fit it into the deck.

Please let me know your thoughts on this.

I think Im jealous of your Imperial Seal and Grim Monolith!! Nice score. From there I think an Underground Sea might be in your future. Anyway, correct me if Im wrong but this is primarily a Doomsday deck with Aetherflux Reservoir as a backup. Doomsday is awesome because it takes 1 blue mana to win if you have the right cards in your deck and 4 islands. You should try to build your deck twords that goal. Islands should make up about 85% of your land base not because of High Tide but because of Gush\Doomsday piles. From there High Tide gets stronger and your deck will have a win by turn 4 or 5 with protection 70% of the time.

Sgtpopnfreash the deck can easily go for a Doomsday with Aetherflux Reservoir as an alternative win, or the opposite Aetherflux Reservoir with Doomsday as an alternative, but I usually tend to Aetherflux Reservoir win, using Isochron Scepter + Dramatic Reversal, Paradox Engine and Yawgmoth's Will to enable enough storm to kill.Ad Nauseam can easily settle both types of win as well.

What Im saying though is that Doomsday should be your primary because it is much much faster. So you should build your deck to focus that win with an aetherflux reservoir backup.

Sgtpopnfreash Made some updates on the list. Managed to get the lands and the counters I was needing.

That looks super good. Have you liked Snapcaster Mage? I took mine out a while ago. After thinking it through I sort of like Mizzix's Mastery more even though it hardly ever gets overloaded.

Sgtpopnfreash, both Snapcaster Mage and Mizzix's Mastery Improve Intuition plays and enable recasting Yawgmoth's Will and Wheels from the grave even without kess, which is a good redundancy in this case. I'd probably cut one of them if I had Timetwister and Candelabra of Tawnos.

I've add Final Fortune to improve my Ad Nauseam and Doomsday plays. I'm actually testing it and I believe it can find its slot even without Sundial of the Infinite. Have you ever considered it?

I have not thought of final fortune like that. That is an interesting idea though.
