Get 5* unstoppable colossus or dupe 4* unstoppable colossus

MKULTRA

I've basically got enough loyalty to get a 5* colossus or get two 4* versions of him which will obviously awaken him. What'd you guys think i should do

You'll only ever use him in Arena so a 1/25 5* is worth much much much more than duped 4*
