I've been trying to figure out what my next faction is going to be. None of the xenos really appeal to me and it would be nice to have something to go along with my marines. I had been thinking that IG would be it, but that would be a lot of work. Knights on the other hand are a lot quicker to get to playing and soak up some points fast. If you had to pick three as the base of an army with some space marine allies, what would you pick? First, I don't really know anything about them. Second, while acknowledging that I'll never win a tournament, I wouldn't want to waste money building a ****ty combination.
