She is definitely naive and has a habit of getting into trouble sometimes with intending to help and do something and getting over her head, yes. So that tracks, haha.

I feel like maybe her mentioning her seeing the future in canon could help him remember more regarding memory charms or something? Or Divination lessons with Trelawney, lol. Not that I recall if Draco took that class but he prob at least knew of it. But Sakura has more magic than just the cards, the cards are just the most active/obvious part.
