I agree on the emblems. Probably shouldn’t have put that in the original post.
I am currently sitting in high platinum and push into Diamond most days. Li Xui is my current tank and I drop 150-175 cups overnight every time I hit Diamond. And I expect to. I’d like to have a better defense. I know any defense I put up in Diamond will be beaten. But I’d like to be defending in low Diamond. These 5* are my only real choices as replacements for Li.
As for talent synergy I am missing any fast 5* snipers, Khiona is my biggest hitter. I know any team with Mitsuko and Onatel will be relying on a bad to below average board to win. I could stop Onatel at 3/70 and finish Justice instead. Just have no experience with her. My thoughts on a 5* lineup that best utilized my heroes was:
Current defense: BT-Isarnia-Li-Khiona-Evelyn
New Defense: Rigard - Isarnia- Onatel - Khiona - Mitsuko
Evelyn - Isarnia - Onatel - Khiona - Mitsuko but no heals
or swap Onatel for Justice
