R5 4*/r3 5* rank up suggestions
I have a couple choices:
Science: YJ, Hulk, Abom, SG, JFX, AM, Rhino, Rhulk, OG cap (already have spidey, capww2 and Electro at r5)
Cosmic: MM, CM, Gamora, King Groot (already have Thor and Phoenix at r5, 5* CM at r4)
Skill: Karnak, BW, Electra, WS 4 and 5*, MK 4 and 5*, Falcon (already have CB at r5 and 5* HE at r3)
I preferrably wanna save Cosmic for Hyperion, Skill for GP and Science for Quake (prestige), but wondering if there's any you'd R5, or give some insight if there's any worth it.
Thanks!
