Is Carlotta a meta?

I was saving on Brant and was already on 70 pity but my sibling thought that it was funny to click the 10 pulls on my account. I got Carlotta.

Is Static Mist good? This is all I got. I also just started Rinascita so I don't have any of the new echos. Is the old Glacio Echo set good for her? What's her skill priorities? I'm prefarming for Brant so I don't have much materials. I'm f2p btw so if she's meta, I can at least be happy 😭
