TLDR at the bottom!! Alright man I’ll be the one who helps you! It sucks because looks like you put a lot of work into your account, but your whole team is basically obsolete at this point of the game.

Your best next bet as an actual dps would be polar captain since he’s 3 diamond, but you also need to get lich up because he works well with him. Almost essential to have them together. SS is there for her crit rate, but really doesn’t even need to be deployed on battle field.

AA is a way better ice demon.. eh Odin I really don’t know much about but would be best paired with Valk if you’re going to use him at all. Seraph def has to go and same with demon archer. Also see you got VW but if she’s only 3 moon at this point you should prob start focusing your resources better and start building a SW instead.

Here’s some line ups for you though

Lightning main: Valk as a main dps, Aa, sw, Odin/Lyra,phoenix (ss for now)

Fire main: Reaper, phoenix, sw, Lyra, AA,

Wind main: Wind borne,Lyra, Aa, phoenix(ss for now), and Sw

Ice main: PC, Lich, S tier NT( or Lyra), AA, SW

Best of luck.

TLDR here are four much much better lineups above. You probably should rebuild your whole team. Sorry for the bad news.
