This deck runs two play lines: a Brood+Absorbing Man and a Debrii+Absorbing Man.
Brood+Absorbing Man: Use forge to buff Brood, copy with Absorbing Man. Compliment with Patriot and Silver Surfer. Mocking Bird will be a 1/9 can be thrown down with Blue Marvel on T6.
Debrii+Absorbing Man: This has been the most fun and I think successful. T3 Debrii + T4 Absorbing Man has been super disruptive on my infinite climbs (not seeing much destroy at all). Compliment with Blue Marvel and Patriot to give your rocks buffs. Rocks can block Wong Setups, Cover spaces for Angela, stop a Onslaught/Ironman Lane. Just generally be an absolute pain.
Downsides: Killmonger destroys the Debrii playline and Enchantress/Rogue can ruin either. But at least on my climbs both are pretty rare, and if I see destroy early I go for Brood instead. Also a resurgance in Elsa has been a little tricky. Mockingbird is almost always a 1/9 unless Iron Lad can hit doom early. Cosmo is also a star. I pretty much always have priority on T6 and a late Cosmo wins me lots 8 cube games. When their board has 4 rocks on it, it can be easy to tell where Modok/Hela/Blob/etc. are going to drop
