Rank up Dilemma!

Skubalon

Ok, I'm working through Act 6.3 and 6.4 and I am at the point of ranking up a few champs. Here are the candidates:

6* Red Magneto to R2
5* Apocalypse to R5
5* Wolverine (Duped) to R5
5* Guilly 2099 to R5

I do have a 5* Professor X as well for the Mutant synergies.

Thoughts?

Mags. Mags destroys act6.

can't go wrong with any of them, but red mags might be your best option.
