With AKH being the final iteration of the Duels meta, this post contains probably final decklists for Duels.

Disclaimer: Most (if not all) of the manabases in this thread are based on an excellent analysis by Frank Karsten. Look here if you want to know why I want 18 White sources for Gideon or something similar.

Not 100% sure how to sort the lists (since "meta decks" are not as important anymore; hence most of my categories fall flat).


() Draw-Go Control
Counter-based control deck. White splash for Radiant Flames and Nahiri.


Midrange
What menaced the Standard metagame with Chainwhirler is also a very strong and serious contender within the Duels meta.



Weenie-lance
A slightly different take on mono-White Weenie; this deck wants to really go wide and make use of the vigilance given by Trial of Solidarity and Sandstone Bridge.



Midrange
Goodstuff deck. Lots of powerful tools and threats; and the easy manabase of them all is the icing on the cake.



Superfriends
For the sake of the multiverse, 13 Walkers will keep watch.

Added Izzet Prowess/Surge, as this is the list I've been having the most success with recently.
Not adding Selesniya Tokens for now, as I haven't playtested the list myself and it's more of a rough concept than a refined list; judging by the replies I got, it seems to be a very decent starting point, though.

Tokens is a good deck. Definitely in the top 10 I have tested and fun to play.

Added a link to the guide about Izzet Prowess/Surge.

Would it not be better to keep both Fevered Visions and Jace for your deck?
is Grip of the Roil a much better card here than Brute Strength
I suppose Grip of the Roil can be used for offense and defense (+card draw) ... :-\ *sits down* Although I like the idea of my Jhessian's hitting through..

I also like the idea of my Jhessian Thieves to hit through. Grip of the Roil helps with that also.
The cost of 2 Mana at minimum might put people off, and some run Rush of Adrenaline, which is just better for this deck than Brute Strength. It's up to discussion whether you're better off running Grip+TITI or Rush of Adrenaline + Jace (which is pretty much the decklist Gegliosch posted earlier)
I'd like to be able to keep Jace, but what's the cut for him? Going down to 20 lands doesn't seem viable, all the Prowess 2-drops are better draws late (although WeCoexist started cutting them), I need all the 1-mana-spells, Jori En is too good to not run twice even if the second copy is dead in your hand.

Added Selesniya Tokens (finally).

(For your Eldarzi Ramp)

Replace Sylvan Ranger with 2 Oath of Nissa and 2 Matter Reshaper. Both do the same thing better.

Explosive Vegetation is a bad T4. I'd replace it with the deathcap/dec stone once you unlock them. Also replace the 4 Evolving Wilds with 2 forests, a waste, and a plains.

Haven't played that list in a while.

How does Matter Reshaper help you hitting your land drops? That doesn't make sense to me. If I remove the Rangers, it'll probably be for the second Cultivator and three Warping Wail (to really ramp out).

Explosive Vegetation is one of the central pieces of the deck and will not be cut. That beind said, I had some ideas of cutting From Beyond, as it doesn't have the impact I hoped for.

Evolving Wilds has to be in this deck to consistently enable Ruin In Their Wake t2. Yor basic idea of adding more basics is correct, but this specific deck needs them (also, they're good with another change I'd make to this list).

The one thing I'd definitely do is add 2 Tireless Trackers over the Reclamation Sages and add the second Declaration In Stone.

Lol I'm done.

Oath of Nissa does not do the same thing as Sylvan Ranger at all...

Updated Selesniya Tokens/Clues.

Added a guide to Selesniya Tokens (work in progress).

Major adjustments to the Drazi Ramp list.
Most notably, it is now Golgari instead of Selesnya (more precisely; it's splashing Black for The Gitrog Monster).

I found that my current take on the Ramp deck in Selesniya was just too passive. Instead of removal, Wraths, Avacyn and Eldrazi Displacer, I found the deck just needs more threats right now, as well as a way to ramp into them most reliably. I didn't find that White assisted in this matter enough, so it got cut.
The Gitrog Monster fits into a Ramp strategy very nicely, and the splash is very easy coming off 2 Cultivators, 2 Woodland Cemeteries and more than enough ways to find the single Swamp in the deck.

Added my Superfriends list; updated Selesnya Tokens.

Added an Eldrazi-less Superfriends version.

Added two experimental lists in Jeskai Mill and Blue Superfriends.

Unfortunately I haven't gotten a lot of feedback on these two lists thus far.
Comments and thoughts are highly appreciated; especially on Jeskai Mill as I am not the most experienced deckbuilder when it comes to Mill.

Minor adjustment to Classic Superfriends' manabase, started to denote some decks as "Outdated", as I didn't work on them for a while, yet I don't feel like removing them completely. Maybe a version of Selesdrazi makes its way back into here as well (though I'm not sure if ramp or more mid-range oriented).

Modulo:
For Jeskai I would recommend:
Cut:
2 x Brutal Expulsion
1 x Geistblast

Add:
1 x Gideon, Ally of Zendikar
2 x Planar Outburst

Gideon does not have any particular synergy with your deck, but he is just too powerful to ignore imo. 4 turn clock, excellent answer to planeswalkers. Defending yourself with his tokens is a great way to force your opponent to commit more to the board before you wipe the board. Outburst gives you the best board wipe in the format, and it even scales with awaken. Your deck is nearly creatureless and you should exploit that by running all 4 wipes available to you.

Expulsion can potentially give you 2 for 1 at instant speed, but outburst is better 90% of the time, and you do not need an instant speed spell in what is otherwise a sorcery speed deck. Geistblast can offer some cute combo stuff but I would not want to draw multiple copies.

24 lands seems a little low but you have so much draw power it might work out OK. I might cut one impulse to get the 25th land but I would want to see how the deck plays before doing this.

I would at least swap a mountain for a plains to accommodate the WW costs.

@HenWen: I think cutting Geistblast is a mistake; the card is too important. I might have a cut for Gideon (or one Planar Outburst), though; Ulamog has not been performing. I'll have to adjust the manabase around though; so it's not an easy swap. (Might end up just adding the 25th land over him).

Also, I will likely put Izzet Surge up to date. My list was designed to beat W Humans reliably, but that deck is not seen nearly as often currently; and against more control-oriented strategies I'd want to add some burn power. Grip of the Roil will get cut as will some Fiery Impulses. The easiest additons would be just 4 Rush of Adrenaline and 2 Exquisite Firecraft (alongside a 21st land); maybe it's better to move towards some Madness ideas with Lightning Axe, Fiery Temper and some number of Just the Wind. Not 100% sure which route to go down.


I added my Esper Control list, which is mainly based off HenWen's and divinevert's Esper lists.
