Kari Zev is legit good; a 2-drop that basically attacks for 3 and is incredibly hard to block.
Her Expertise is less exciting, but: Red aggressive decks don't hate Act of Treason, and this card is much better, probably Red's main answer to big Vehicles which could otherwise be a Problem.

The Black Demon is good I think. He looks very expensive, but in the correct decks he's more of a 4- or 5-drop, and he puts the wirst case on every artifact at being a Disfigure.
Sure, Demon of Dark Schemes looked a lot fancier, but this one is pretty similar in power level, if not better.

I'm a lot less excited for the Aetherborn Lord; artly because there is no way to create Aetherborn tokens yet. Also, 4 mana is a lot...

The Common cycle that creates Servos from Energy is looking good; Green and White got the short stick here, I really like the Black one and Blue and Red are fine.

New 2 drop Deathtouch critters are always good, especially at common.

Alright, today we get the AER pre-pre release on LoadingReadyRun stream, the remaining bunch of spoilers and the Duels' update video.
Welp, hopefully epiphany brought some sweets for everybody.

The two drop looks sweet actually, and we need better red two drops in duels as well.

Act of Treason + free 2CC spell for 3 mana is more than ok...even more with the sacrifice effects that seem to be coming, like Intruder, for example

And the Monkey triggering Revolt at end of combat, not turn, is just sweet...probably better than he staying alive, Revolt is everywhere

Kari will go right into my Valor of Akros.dec!

The only thing hoping for with Kari Zev is that they fix the declare attackers step. Have the possibility for the monkey to attack somewhere else than face; and finally resolve the disconnect bug with "attacks each turn if able" creatures.

Dunno about that Aetherborn lord, there doesn't seem to be enough fully usable aetherborn never mind aetherborn that would work together in the same deck to dedicate a lord to it.
Maybe in a few years and we return to Kaladesh and get even more but then Duels will definitely be dead by then and it's a long time to wait for something to become useful.

Full set is out: http://magic.wizards.com/en/articles/archive/card-image-gallery/aether-revolt

Dunno if this was spoiled before, but this certainly has it's uses.

Displace meets Acrobatic Maneuver

You can fix everything, Duels! You can save everybody!

Negate's getting reprinted - we can not get it again!

This one looks kinda sweet...

Infinite +1/+1 with Wandering Fumarole ?

I know this has been spoiled, but man, I really hope we get it to make Ramp viable again.



Good green option if Vehicles become omnipresent. Obvs no Naturalize, but it's all we got.

Yep.

that office video links to First Aid Fail after which has to be one of their best moments ever. omg it's so hilarious

So infinite power at 4 power. Could easily be the new UR Infect deck, ala Pummeler.
