Need help with a team for squad arena lol

Hello everyone!

So, I've been trying out different teams for several days now, and I can't seem to break through in the arena. I'm having trouble against opposing teams, mainly Jedi Master Kenobi, and since I don't consider myself a renowned player, I'm always looking to learn more about this game. I wanted to know what the community could tell me, what team to make with the characters I currently have, which ones I should make, etc.

I'm all ears, thanks in advance!
