Managed to get the 2-3 gem from the free key today, so have an unexpected rank up choice to make.
Here are my options:

I’m probably leaning towards Red Skull the most despite him not being awakened. Yes, I know many would probably recommend Nefaria since I’ve got him awakened, but I’ll admit I can’t really get down his punish special/evade mechanic so not sure I’ll ever be able to use him to his full potential. That said, maybe I just need to get over it and figure him out. Of course Odin might be a solid choice. Mojo’s stock is down since I grabbed Sparky in the July 4th event and as such don’t need to do the Fintech challenge any more.
In addition to these, the only real R1s I would consider are Peni (awakened, sig 100) or Enchantress (unawakakened). However, I’ve got a 6*R5A max sig enchantress and I feel like Red Skull is a better tech option than Peni.
What do you all recommend?
