While I have my doubts about it ever happening, with the Rise of Eldrazi and WOTC seemingly being a little more adventurous in its designs as of late, I was curious what people would think about a purely colorless Moxen. WOTC has shown with slight modifications like that of Mox Opal it can make Moxen that are balanced enough to see play but still powerful enough to entice Vintage players, and they seem to like to print a new one every so often (Stronghold was 98, Mirrodon was 2003, scars 2010.) Plus with the fancy new colorless symbol you know someone from R&D already forwarded the idea.
If they made a colorless moxen, I think it is safe to assume Legendary at this point, but how much turmoil would it throw the format into? Would it instantly become one of the power cards? Need restriction? What other downside would it need to have to be tolerable in multiple formats? Maybe it could pain you anytime you tap it or something?
I know this is all fan-crafting at this point but I do not think it would be totally unreasonable to print one at somepoint. An off set like Conspiracy or Commander is the perfect place for it so why not?
