PROJECT: Bard? Emperor Taliyah? Debonair Mordekaiser? Starbucks Syndra? ...What.
Like, for one, I don't think they'd really be able to do anything literally based off coffee shops or restaurants or anything (and on top of that, those skins wouldn't even really look good as far as I can imagine)
Second, you realize that some of these make zero sense, right? Debonair Mordekaiser doesn't fit, PROJECT: Bard doesn't fit, and "Emperor" Taliyah doesn't even make sense. Taliyah's female, she'd be an Emp_ress_.
And some of these don't look very creative, either - "Land Shark Rek'Sai" - you mean Default? "Solar Goddess Leona" - they tend to make skins to do something new for a Champion, why would they make "Solar Goddess" when she's already something of a Solar Cleric/Templar?
And what would "Final Form Zilean" even look like? I wasn't even aware he had forms.
And, like Blaiz Fenix said, a lot of the rest of them (PROJECT: Bard and Debonair Mordekaiser included) are just slapping existing skinline names on random Champions.
