Looks like we'll have switch for all them and I think only candidate for ww switch would be Lizgard. So final teams would look like
- bb: Candrid, Katja, Mathilda
- br: Nox, Yrsa, Astrid
- ww: Astrja, Sonja, Lizgard
Makes sense tbh, fighters in ww, tricksters in bb and wit users in br. I can see how mathilda switches to bb. She have cordial relationship with Candrid and despise Astrja&Astrid duo. I think she wouldn't accept Astrja leadership and seek refuge with Candrid. I don't see a clear way for Lizgard make a switch though, only possibilty I see is by huge influence of MC and Nox will send her for Astrja's protection while takes Astrid under her protection. We'll see I suppose.
