The zeta dilemma

Since you are using ep lead. Zeta his leader. It’s well worth it, as for the other. . .

Palp lead and if you use chimera, Thrawn

Palp lead and Thrawn unique for sure.

I'd also consider putting Tarkin in place of either Yoda or CLS on your arena team. You're gifting opposing Vaders a +16 speed increasing while losing that yourself. Tarkin will cut that in half.

I'll agree with Vendi. Palpatine Leader Zeta and Thrawn Unique Zeta.
I would also take both CLS and Yoda off of your team and put Tarkin on, and some other sith or empire toon. Looks like you maybe have a decent Maul, so maybe him.
By having Yoda on your team (a Jedi), you are granting enemy Vader +8 speed, and because Yoda isn't empire/sith, your Vader effectively loses that much as well, so you lose 16 speed, effectively. You lose that same amount with CLS (a Rebel) as well, losing you 32 speed to a full empire/sith enemy team with a Vader on it.

CLS and Yoda may be great, but on your team, it's just hurting you. Palpatine specifically hurts Rebels and Jedi.

Thank you all, I have put my first zeta on palp and just awaiting more omegas to zeta thrawn. And thanks for the advice I never saw it like that, I just use Yoda and CLS because of their power. ?

Zeta revan.
