I don't know about you, but this is my headcannon for what @hermionegranger will look like when she grows up. While Yugioh has no shortage of lady spellcasters, I feel like Witchcrafter Genni — https://yugipedia.com/wiki/Witchcrafter_Genni — comes closest to Hermione, at least in terms of looks, even if the latter uses a wand not a staff, and doesn't wear glasses.
I considered making her an EARTH monster, since Hermione is very down to earth, but FIRE probably works better since it's the Gryffindor element, and she did use fire spells on occasion.
And yeah, Spellbook — https://yugipedia.com/wiki/Spellbook — is a real archetype in Yugioh. And there are a few Library cards, like Royal Magical Library — https://yugipedia.com/wiki/Royal_Magical_Library —, as well as some Potion cards, like Brutal Potion —https://yugipedia.com/wiki/Brutal_Potion —.
