In the previous Shan Hai Scrolls gacha, only the Aatrox skin (the legendary one) had an emote for it in the exchange store, so if we follow the same modality, the legendary in this case should be Ahri's because it has an emote.
If it makes you any better, I HAVE A THEORY!! I saw patch 5.2 accessories part 1 on yt, and saw that the old crystal rose borders are coming back. Borders usually come with skins, so there MIGHT be a chance that its not only an event for new skins but also a rerun for old skins! Maybe CR akali, who knows.
