Raze with the deadlock would go superb with the comp. Also very good with fade and kayo.
Harbor cascade to block the choke. KAY/O knife to suppress enemy util. Neon wall (the one Saadhak threw in their game against EG) for Neon and KAY/O to scale up. Fade eye comes in, potentially revealing any enemies past the Harbor wall, which Neon and KAY/O can shoot through the wall. KAY/O can also pop flash through the wall for him and Neon to fight. Fade could also potentially scale up with Neon and KAY/O, help them fight, maybe throw a dog or seize toward the choke. Meanwhile, KJ is spotting Mound while Harbor is holding a high-low with KJ's turret on the boxes in front of B.
(This is a WIP but this is how I'd take Rubble with the comp)
