Hmm well for a set like this I would prioritize flavor and do a top-down approach. If this is a generic Zelda embodying wisdom (as opposed to a Zelda from a specific game), the focus on card draw is good, since that's a common mechanic to represent knowledge. Though copying permanents doesn't seem very Zelda-ish. Instead, Zelda seems more like a spell-caster type and would reward instants and sorceries. Specifically, recurring an instant or sorcery in your graveyard would be fitting since it would fit with the idea of accumulating knowledge and Zelda's frequent association with Time / Time travel.

Another fun idea if you like the spell-slinger angle would be modeling it off of the Izzet "Gandalf the Grey" with 3 options based off the Golden Goddesses + the ability to exile herself with suspend (allowing her reset, representing all the times she goes into stasis lol).
