Endor Escalation - Minimum, best Team, Strategy

My own experience so far:

• Chirpa L (6*, g8, omega tribal unity, moderate mods)
  
• Ewok Elder (7*, g8, omega power of forest, no mods)
  
• Teebo (7*, g9, omega all but scramble tactics, moderate mods)
  
• Ewok Scout (7*, g8, no omegas, no mods)
  
• Logray (5*, g8, ability level 4, no mods)
  

Get as far as 3rd or 4th round of battle.

I also have: Wicket (4*, g7, ability level 4, no mods)

Last time, I tried putting arena mods on my Ewoks, still couldn't get anyplace.

So trying to figure out which ones to gear up/star up.
