My Wolveroach account is firmly in 4* land, I’ve been using Vulture, Red Hulk, 4* Cyclops.
Boost 2 green/black, 1 all, get a black match pronto to get Vulture airborne. Match more black ready for when he lands. Before firing Circling Prey, check blue. If enough to fire Hybrid Tech Slicer, don’t, fire Called Shot instead. As soon as you have 18 green, maybe boosted by Gamma Syphon, fire Hammer & Anvil. Fire Combined Forces as soon as you have 10 TU AP. Uncanny Strategist can help get more red.
It’s been surprisingly effective, even against Round 8.
