Come on everybody know all of the names above deserve to be 4* or possibly 5*. I would spend every moment in this game to get World War Hulk, Thanos, and the silver surfer. Maybe even ODIN! I’m just saying do some unexpected and surprising. You might regain some vets and more newbies. Just Sayin
Judging by the time commitment that is needed to get all 3 HB covers in Ultron, yes, you WILL spend every moment trying to get those covers. And any other free time you have. And then some.
My forum name should tell you who I’m all in for adding to this game!
