? Wonder what skin will come out next ?

Ok I've limited my theory on either A.) Super Galaxy skin B.) Blood Moon C.) Project

Seriously tho, every champion has one or all of these and the newer skins that Riot's coming out with is no different. I understand coming up with new skins is difficult but can't they just look at movies and go " Ok, let's rip that idea off" they've done it before so why only stop with just these 3 skin types?
