The comp is:
Chamber
Harbor
Sova
Viper/Astra/Omen
Gekko/KayO/Breach
Essentially, Chamber fills two important roles of oping and holding site/flank, essentially combining a Jett (oping part only) and a Killjoy into one, slightly less effective version of both. The reason for this is to open up other roles - namely, double controller and double intiator.
Harbor is I think the best smoker for this map, he's the only smoker that can effectively smoke B and he should fit well with execs and postplants.
In a relatively big map like this Sova seems like the best choice for an initiator.
Pairing Harbor with another dome smoker is kind of ballsy but I think it can be done on Abyss, Astra can make up for the lack of defense, and Omen can too a little, but also add an extra layer of entry since there isn't a Duelist. Viper of course synergizes with Harbor well already, and also adds defense that the comp somewhat lacks.
Finally, I think double Inititator will be pretty strong on this map - execs will be common and there's a lot of angles to clear, particularly on B. Gekko facilitates plants well and his Dizzy is excellent info. KAYO is great for execs and has lots of util to stall - same with Breach. If I had to guess I'd say KAYO/Breach works better with Omen, and Gekko works better with Viper/Astra, with the former being slightly more exec-leaning, and the latter being more post-plant-leaning.
