No champion isn't viable in some way
Not being absurdly broken doesn't mean you aren't viable. Being a niche pick doesn't mean you're not viable. Being a lot weaker than other champions doesn't mean you're not viable. Even Evelynn and Elise are plenty viable right now. There is not a single champion in the game right now that is 100% not able to perform well in any role at all.
