This was to primarily highlight Yuki than team comps. Hard requirements is a decent OD breaker and dispel. Zethia is good for overall/early DPS (Amp) while Sylas brings afflictions/dispel which is perfect for CoN content and LKai to a degree. So both are pretty good to choose depending on what you need. LKai might cause a bit trouble since AI are trash at dispelling him due to shield rejecting SP regen. If you gotten Joker from way back then he trivializes LKai so hard that any character you bring can braindead clear it.
The only thing needed is a strong FS charachter. Vida, Linnea, G!Chelle or S!Leonidas. The other teammates are variable. Mine is Patia, Grace, Joker and G!Chelle
For him, I used Grace, Cleo, Alberius, and Zethia. Grace gives Life Shield, Cleo keeps Grace alive and dispels the adamantine shield (which Grace also does), Alberius is DPS, and Zethia has a dragon drive that she uses when you're not controlling her (for free).
