Neon, Raze, and Phoenix(as secondary duelist) all look super viable.
Chamber could actually go crazy. There's probably a lot of really good TP set ups, and lots of nice op positions. Cypher could also go crazy with locking down some paths which require jumping over the abyss. Depending on how strong the op is on this map, iso might finally have a map where he's useful.
Omen will probably be the most picked controller with his TPs and all the elevation changes. Although astra could probably set up some good trap plays.
Initiator wise pretty much everything goes except Gekko. You don't want to send lil bro to his death.
