Who better to rank up: unduped 5* Mordo to r3 or duped 4* Magik to r5
At this point in the game (with the possibility of 6* champs coming), would it be better to rank up a 5* Mordo who is not duped to r3, or use the T4 class cats to rank up a duped 4* Magik to r5? I see pros and cons for both and would like input. Thanks!
