It's less about "The Guardian" as that's just prophecy mumbo-jumbo.

Emma was able to use her light magic (to some degree), as Ana can. Apprentice uses magic, presumably light magic.

Who knows about the Dragon.

Gothel is part of an anomaly as she really didn't appear to have magic, but then she did. Like, in 7x06, she used magic ingrained in the hyacinth imbued with belief. In 7x08?, Ivy was making fun of Gothel's weak magic. 7x10, Gothel's blasting open doors. Something is missing. I think they deleted a number of scenes.

It's clear that you still have magic in your cursed form (as Ivy still had it, despite never using it). Oddly, Rumple still seems to no have magic, even though he's surely knowledgeable by this point.

It's a weird case of "What? Who?"
