As we these are the elements that Team 7 has:
Boruto
- Fuuton
- Raiton
- Suiton
Sarada
- Katon
- Raiton
- Yin Release (she can do genjutsu like a pro)
Mitsuki
- Fuuton
- Raiton
- Yang* (not sure)
Team 7 has got in total 4 elements plus Yin element. The only element they are missing is Doton, Yang and Yin/Yang. By elements Team 7 is really powerful, there is no weak. I don't know if Mitsuki Sage Mode counts and Yang.
