What is the bare minimum to complete endor escalation? Which five ewoks are best to complete it with?

Natos

I've done it with Chirpa Lead (G8, 5*), Teebo (G8, 7*), Elder (G8, 7*), Logray (G8, 6*), Wicket (G8, 4*). Still have some omegas to go on all of them. Just the first tier though.

Wicket g8 6star lvl 80 no omega

Teebo g9 7star lvl 80 basic omegaed
