Arcade Azir Skin Idea

Just got this incredible idea for an Arcade Azir skin. I think it'd be awesome if his ult were to be an incomplete line of Tetris and when it vanishes after it's duration is done, that final line is filled with a vertical Tetris piece, and the wall clears the way it does in Tetris.

For his passive, it's a tower and a game of space invaders.
