I hope they include Yzma.

Another thought I had was The Fates from Hercules could make an appearance. Obviously not as grotesque as they were in the film. But one of the actresses on 7x15 does has blonde hair. I mean, they could've appeared in the Underworld arc, but I'm sure Gothel would find them interesting to be in her coven.
