Help with Forest Moon tier 1

I struggle a lot with this tier and I haven't had any problems with the tier 1 and 2 of other assault battles, even though this is supposed to be easier.

I have Vader, Palps and Chopper at G9, Tarkin at g8.
Then I have royal guard and tie fighter pilot at g7.
I have thrawn and snowtrooper but they are basically at 0.

I am posting my link here and I would much appreciate it if anyone has any tips on how to handle this ewok nuisance. Or am I way off on having the bare minimum standards?
