Mecha/Battlecast Karthus

Another skin concept that was posted a long ago, but this time, not by me. (http://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/t7Bjn4qn-mecha-karthus-skin) I really like this concept because it is completely different from the Shadow Isles-themed lich we all know.

It could even be made into a legendary skin since the current Karthus' quotes are not really fitting for a mechanic skin.
