I just got her finally! But Dialyn isn't available, so what do I do for her 3rd team member?

The reason Dialyn is not available is because she's in my Yixuan/Lucia team which is my best team by far. I have no idea who to put in here. Zhao is in the team, so who should the 3rd slot be? What I have for options are every A rank and every standard S Rank, Cissia, Yanagi, Astra, Vivian, Evelyn, Ellen, Alice, and Yuzuha. I'm saving the rest of what I have for Remielle so Sunna's rerun is not an option for me. Thank you!
