Which Mystic to rank up?
Currently I have 4 Mystic T4C and a few interesting options. Could take 5* Magik to r4 which would be my first 5* r4. or take 4* Scarlet Witch sig 21 to r5 even though she's not at a high signature level yet. Also, just got 5* Dr Voodoo unduped, but I hear he needs to be duped to be good.
