Even without knowing their ancestors, they would still be a badass team because Boruto is a prodigy, Sarada has the sharingan and a calm, smart personality, and even though we don't know Mitsuki's powers it is unlikely that he is anything short of a badass. This is the first time I've seen a team where all three members have exceptional potential. I hope Kishi doesn't try to weaken one of them and shows just how capable they are.
