First off, those are some great reds. Hard to say which one to drop (Anchor would say Mitsuko, but I absolutely love her and think she’s underrated).
Second, saying they’re the best you have is wrong. You have some maxed 4s I’d hope. Put them in until you get a 5 to take their place. At least for one. You can do 2 red, but you’ll likely do worse than a well balanced rainbow. But it’s better than now. If yyou do stick with 2 red, one should be Mitsuko to counter blue stacks.
Victor is certainly worth leveling, especially since your other purple 5 is Mok (I’m sorry). He’s not my favorite purple, but he is very effective with the defense buff and damage.
