"Battlecast Skarner and Kog'Maw's promotional website featured the silhouette of a create with wings, similar to those on  Riot Kayle "

Glad I'm not the only one that noticed the winged Battlecast unit teased in the promo. I wonder if it's the same one from the BC Vel'Koz splash and the Creator Viktor's recall screens.

Also, the shapeshifter champ they promised is probably Rek'Sai. :)
