[@Hylozoist] I apologize in taking so long in replying to your inquiries. While I am [url= http://gatherer.wizards.com/Handlers/Image.ashx?multiverseid=409737&type=card]Always Watching[/url] this thread, I actually had to think about your questions plus I was at work and could not steal away long enough to reply.

Ok, I have decided that I will allow colorless to be a primary color, however I am unsure if I want to allow this choice to lead to a planeswalker wielding Eldrazi Magic. I might if they come exceptionally Lovecraftian. 

As far as myr, I have an exceptional weakness for those metal robots. I started playing magic back in the Original Mirrodin (yes the most broken set of magic) and my original deck was a mono blue myr tribal (Yes, I learnt to play blue first.) [url=http://gatherer.wizards.com/Handlers/Image.ashx?multiverseid=46556&type=card] BroodStar [/url] was my amazing finisher if myr did not seal the deal. From the known lore, The height of the myr's relatively primitive culture was just before the Phyrexian invasion and it is unclear how the virgin race will handle the Phyrexian occupation. 

All that being said, I accept your character. Your origin story is exceptionally cute and hilarious. I imagine the industrious and scientific myr doing just that. Alexander would definitely like to have a stern word with your myr. Anyways, Please post your character over in the CS thread.
