In "A Hearth's Warming Tail", when Snowfall sees the Ghost of Hearth's Warming's Past she comments "I didn't cast any spirit summoning spell". Also, in Ogres and Oubliettes, there are skeleton ponies. In 28 Pranks Later, the ponies of Ponyville imitate zombies. I also believe that Spike mentioned something about zombies in the episode where Zecora debuted...? Nonetheless, Necromancy definitely exists in MLP:FIM, though we never actually see it occur (though the resurrection of the Pillars could be argued to be necromancy). The argument that "it's too dark for MLP and isn't fitting of the theme" isn't a very good argument, for MLP has lots of dark themes and hints of very dark things throughout the show.
