If your playing for fun, there is never a time a Yuzzem isn't good for the squad. On a tourney level for your Lobot reserves it is whatever you have that will beat the opponent. In my local meta, I have to bring in treadwell droids a lot lately since my players seem to have a hard-on for Nom and self distructing Vong.
Generally I would say anything that could take shots while you move Kreia into combat. That might be lots of Rodian Brutes or Mouse droids, just whatever you think will work.
