I'm stuck in Silver RTA as a new player returner actually, but it's been so long it barely matters. How the fuck do I deal with BBK short of prebanning her? SB S3 just wipes me constantly.

The units I have to work with are
>Landy
>Celine
>DB Senya
>Lidica
>FCeci
>Aram
>Rabi
>LQC
>Krau
>ARas
>Ruele

Technically AColi, TSurin, CDom, and SSB have gear too, but they're apparently all out of meta and have massively underperformed whenever I tried to field them.
Is there someone I can grab with my next Epic Pass Selector that will help? I'm also waiting on Grace cooldown to put either Summer Hwayoung or Harsetti in since I have no resources to build right now.
