I have run Kaustic a few times-
is it just me or does he need a psychogenic, Poison (10) or something more than just Command (1)?
Command is most useful when you can kick some A yourself and then call in the troops- to me anyway....the ability to not do much and then give another an activation never makes it worth much in my book.
The one use I have found is to use Kaustic to Rally then Command the unit he successfully rallied. But this occasion rarely happens except maybe big games.
