I'm still trying to figure this idea out, but Feln Aggro was an idea that caught my eye recently, as well as using Nightfall as an aggro damage accelerant. I have only 1 Miris Nightshade, though, and also lack a lot of Nightfall and Night units. I definitely think the idea could have potential though, but Nightfall in general has very little Set 3 support.
Since this idea is heavily WIP, I am not going to do a really detailed thing like for
Skycrag Aggro: Hailstorm was a Buff Edition. But, this deck relies a lot more on fliers, and is very much a count-to-25 deck. I like the Instigators speeding up the damage as well, however Permafrost and Winter's Grasp are very much anti-combo with that interaction. Suffocate is a necessary 4-of as your opponent's earlygame units will definitely not have 4 attack.
Not sure about this deck's matchups, but people may mistake it for the control version of this faction, which gives some advantage.
