There's Zatanna magic and then there's Doctor Fate magic. He has a direct link to a Lord of Order that can only be severed if Nabu wants it (seriously? "steal the helm"? good luck). He has a mystic cape. He has a mystic amulet. He is very, very schooled in occultism, spellcasting and all styles of sorcery. He is, to steal a phrase, the Sorcerer Supreme.

Batman may know some things about magic, he also knows Doctor Fate is way out of his league when it comes to magic - check Cosmic Oddyssey.
