Who should I rank up?

Hey all,

I'm about to get the 3rd basic catalyst to R4 my next champ and I need help deciding who to go with.

A part of me wants to go with Karolina since I already have 2 mystic and 1 science at R4 but then again, Nefaria is such a badass character to pass up on.

The other side of me wants to refrain from upgrading Karolina since EVERYONE is doing it (which wouldn't surprise me if we see a counter specifically for her soon)

My last choice is Sauron (probably one of my favorite mutant champs due to his utility) so he's another viable option if I want to diversify my roster.

What are your thoughts?

Sauron. First, because he's your favourite mutant.

Second, because he's a dinosaur.
