Young Han solo & Vandor Chewbacca How To Use Them(The Silent Scoundrel Rework)

You left out the other benefit to a Lando lead. It's a leadership ability that can bridge in Rebels. Old Ben springs to mind. He's good on any team, and a Ben who's a little bit faster from Lando is not a bad thing.

Not an arena worthy lineup, but solid.

Bossk is also a strong contender as tank, whether under Boba or Lando lead.

But honestly, without more Scoundrel content, I don't see this Han and Chewie seeing the arena. But maybe once we get more Prepared support, which will probably happen after the movie drops, we might see shenanigans around it.
