Is chasca, mavuika, mona and charlotte a good team?

Bennnet and Furina are already taken on other teams and I dont have Ororon.

I'm enjoying a lot playing this team, maybe is not the best damage wise but I really like it also cause I do Mona E Q and then Mauv Q and damage is quite high even if Mav is a sub dps in this and Chasca doesnt benefit from Mav E.
