Xerath skins

Xerath is one of seventeen champs that haven't gotten a skin since 2015 (plus two that've gone even longer). Now he has a skin for every one of the primary colours (base=blue, battlecast=red, runeborn=green, scorched earth=orange, GotS=yellow) except purple. So it's obvious what his next skin should be. For that last colour I propose he get Dark Star. I feel that'd look good on him. After he gets a purple skin I'm not sure what they'll do with him. Maybe pink?
