Hello all, I am nearing the time for my act 5 completion, and I need to start thinking of a counter to Ultron. I have a 5* nebula at rank 2 and a 4* Medusa at rank 4. Both are unawakened but I am planning to use my generic ag from act 4 100% on Medusa. Also Medusa would be good on defense. However Nebula and Omega are my only 2 bleed immunes. Who should I go for??


My roster for reference
