Admiral Ackbar in Raids

So tonight I will get my Admiral Ackbar to five stars and hope to use him in the tier V raid taking place this evening. Which kind of characters typically work best with him? My most powerful characters are all four ewoks, ST Han, Fives, Old Ben, Dooku, QGJ, Luminara, Dakam Poggle, Sidious, IG86 and Biggs.
Thank you.
