Texas Milk?

Beverly Hillbillies reference?

I fear that I did. By the way, we have a gold color indicator? That's kind of funny, since it tells players nothing.

I know, right? I was looking for a five-color one, but it wasn't there... unless I missed it.

My guess is that if Transguild Courier were to be reprinted, he'd get a gold blob rather than a five-segmented blob. My expectation is that the gold blob would indicate "5 colours", and they won't bother printing any three- or four-colour cards without mana costs.
