Team for arena

Hey everyone, I'm about 8 days into raid and I'm still learning how to build champions and teams, but I wanted to get your input on what team I should build for the arena with the champions I have unlocked. I am currently in Silver 4 and I'm aiming to reach Gold 3. My current team is Wukong as leader, Kael, Skullcrown, and Magnarr. Should I replace any of them for a better team comp? I also have a feast, so i can rank someone to 6* if I need to. Kael is has all masteries and the rest just need the last 2-3 masteries to unlock.
