I can totally see Earthrune Skarner sharing the theme with Galio, once the fellows from ChampUP get around to give him a VGU- That, or an updated Earthrune Skarner that is at least inspired by Enchanted Galio.
But yeah, I'd really like to see what this thematic could become on other champions- Especially Illaoi, Vel'Koz and Gnar, personally.
we also need more Popstar skins
is the only one in that skin-line, which is based on Girls Generation so i don't see why we shouldn't have more
The world breaker skins follow a similar theme but those are 750 RP skins with little to no particle changes. But in terms of aesthetic they match up with enchanted Galio imo.
