Hi guys, I just pulled this:

I am actually VERY HAPPY because I was hoping to dupe and R5 both my Ghost Rider and Mephisto, mainly because of their synergies .
I have R2 6* CGR who would love a high ranked duped GR. For example I have a R4 Man-Thing that I pair with CGR cuz of synergies. But Mephisto has also SO MANY USEFUL synergies too ( for example , I have higj rank 5* Morningstar and a 6* iHulk, among the few that would benefit from having him on the team)
So I'm torn. I guess it all depends on who's sig is more useful and who is the better duped champ in the long run.
Help please!
