It represents intuition, dreams, and the subconscious.
I don't know how that would translate to magic. Its element is water, so probably at least blue, but I imagine they'd make it izzet too. Maybe something to do with scrying and naming cards. Maybe rip off some of the miracle casting that Aminatou had? I am a big fan of "cards in your hand have [insert casting mechanic]" like Jhoira and Bohn.

Honestly now I'm just thinking of cards I want that give effects to cards in hand like
>Cards you cast from your hand have overload. The overload cost is equal to the card's mana value plus (5)
You'd maybe put that on something like The Tower since that's the tarot for disaster
