Arena Help and Nonstop SSR+ Help

Hi, I need some help with Arena, as I’m getting beaten by people with much lower Combat Power to me and I’ve got no clue why. Can I please have some help making a decent Arena Defence Team for both Normal Arena and Ranker Arena.

Also, with the Nonstop SSR+ leaks, I’d like some help deciding on who to choose (Assuming White isn’t included). I think I need another good SSR+ damage unit.

Thanks.
