The 10th Championship owner.

So i've been thinking about the latest championship skins and the old ones, and i do say they look pretty neat. It got me thinking about which champion will own the 10th skin. I have to say ryze considering he has been in the game since development and we all no know that the roman numeral for 10 is a "X". Having the X tattooed on his back whilst giving him some shoulder plates. Another potential champion could be katarina considering she has also been in the game for some time. Having the X on her armor on the back. Others i guess would be,Shaco,Bard,Lucian,Anivia,Blitzcrank and/or Yi I know i'm thinking far ahead of time but at least take a guess.
