Hello again, [@MarsAdept], I've spent a bit of time thinking about things (and looking through some of my rather goofy EDH decks...) over the weekend, and was wondering - would colourless be a valid Primary colour? I ask because you mention that any race is acceptable, providing it's sentient and made of matter, and I've been staring at my old Myr deck while eating breakfast, and… well, you see where this is going, right?

I just want to make sure that this is an acceptable idea before I start writing stuff down for it. I'm happy to go back to the drawing board if this isn't going to fit in with what you've got planned, as the drawing board is cluttered with all kinds of stuff to pick from!
