Doesn't help a lot with colors, and it's not nearlt as good, might as well play Llannowar Elves and get pretty much the same result (yeah, not in color, just an example), since you won't be playing more than one elemental a turn. On the other hand, you could try to squeeze in green to play Firespout, making it also effective against pesky Faeries, play a few more counterspells and fewer copies of some creatures (perhaps even fitting in Primal Command as a tutor and a life-gain cushion). You'd need, what? A single source of white mana? You could even drop white altogether, I think.
