Good in theory, however it won't perform like you'd like it too. It is way to fragile for its points. The commandos go down fast and with a +9 attack they won't earn there points in kills before they eat dirt. Strictly fun squad. (And is sure is one! I love using these builds.)

the flea has a point a strictly fun squad.
If you have to use Xixor he usually works better with Rebels, at least in my experience.
