My current squad is Zenia 7* (lead), Selena 7*, Kira 6*, Bestie 6* and Aaron 6*. But I have been felling that there is something missing in it. I was thinking in taking out Selena from there and putting Rinon but I got Krantz and I don't know what to do anymore...., maybe a Krantz lead, but I need help to make a raibow team

My units are:

7* - Selena(G), Griel(L), Feeva(A) and Zenia(B)

6* - Freya(G), Arus(A), Bestie(L), Stya(A), Eliza(A), Phee(B), Dion(L), Sefia(O), Melchio(A), Kira(A), Rinon(B), Zergel(B), Ivris(G), Aaron(L), Elaina(B).

5* - Regrard(B), Rubeus(A), Atro(G), Sola(A), Narza(L), Shida(B), Madia(G), Yuura(B), Grandt(A), Semira(O), Karl(L), Noah(L), Krantz(G), Grahdens(L)

4* - Lance(L), Paula(A), Zele(L), Fang(A), Lava(G), Aneil(B), Lin(L), Miku(O), Lucana(O), Nevsky(G), Magress(O), Ciara(A)

I know that I have almost none thunder units......

Should I just let Krantz on my current team or should I make a Rainbow one? I can work on any unit that you say, so just please help me
