R4 4* mutant

F317

I have beast, colassus and cyclops blue team. I need to rank up one of them into r4 to back up. Which champ should i choose,? All of them are unduped. Beast is the highest rating, and Colassus is the lowest.

Thx for ur suggestion guys.
Happy playing.

Go with Beast

Out of these, BEAST.

But there are better options among the mutants.
