I've played a few other people on Aetherworks Marvel, most of whom were in Temur, but I don't understand why. Red does nothing to really address your weaknesses. You basically play a third color just to get Harnessed Lightning.
My current experiemental build:
I've got a bunch of flexible spots that I haven't really figured out. Servant of the Conduit, Attune with Aether, some number of wincons and Marvel are pretty much the only set cards.
Basically I've confirmed Ulamog is way better than Emrakul most of the time (and contributes to most of your broken as fuck Turn 4 wins. I'm guessing 3 is the right number since its a dead card in your hand but I have 4 in the last build I did.
The Elder Deep-Fried is the focus of my most recent testing - I really hate drawing dead cards and I was trying it out to see if I liked having an excellent card to dump with Aetherworks Marvel AND that I could routinely cast in games. I like it, but I don't love it enough to say it really should be there.
yes, UW and esper obnoxious but not particularly good. Most ran torrential gearhulk but it's just a vanilla creature once it flashed something back not particularly hard to deal. Dovin Baan is unsurprisingly not particularly pushed, I only use him in the side.
As long as BFZ is in rotation Gx midrange is gonna be the better control. I could very well see Bant continue dominating that.
Aetherworks Marvel might have to shift into Temur since Spell Queller can wreck it mainboard.
Counterspell decks are always annoying in any standard even when they aren't good. They seem worse than they did last season. In fact, BW Control seems pretty bad too, but aggro seems much better than last season, especially the RW Artifact/Copter decks. I can't stress enough that I expect Smuggler's Copter to be a Standard staple card. It's good in everything. I'm not even sure why I don't run it in Marvel (seriously - it loots for Marvel!).
