No champion is that good at the moment. There isn't any pick in the game that gives a free win, even the most banned ones.

Moji is actually not that bad at all. Same goes for Buck and Sha, they all have value because they have a lot of damages and are good duellists (and because Sha is good against Evie and Maeve). On the other hand, Seris is absolute trash compared to other healers. Vivian is one of the best shield destroyers so she has value too.
