Gryffs
Gryffs are Innistrad's elegant, heron-headed species of Hippogriff. Gryffs are longer and leaner than the traditional Innistrad griffin, with flexible necks, sleek hindquarters, lance-like beaks, and equine hooves. Gryffs are swift and nimble flyers, natural enemies of dark creatures, and a powerful force for the side of Avacyn and her angels. They are used by human knights as Gryff Vanguard. After Emrakul's arrival, some Wretched Gryff by the Eldrazi's power.
