My Bears Ready for 7 star C3PO?

Do I need all the basics omega'd though (which ones)? I do not have Chirpa, EE, or Logray's basics omega'd. I'm kind of low on omegas so I wanted to be frugal.

One of the biggest recent fails of my Ewoks was in a GA. My discord bot said that Ewoks were a counter to FO. Well, my Ewoks killed everyone but KRU but could not kill KRU by himself. That's my Ewok test.
