"Medusa Queen"
I don't understand the naming of this card. Medusa was a gorgon. That is, she was one particular gorgon named Medusa. There is only one of her among multiple gorgons. You don't have a bunch of "Medusas" just as you don't have a bunch of "Herculeses" or an army of "Theseuses." There will not be a gathering of "Draculas" to decide which one is the "Dracula King."
I would suggest calling this card Medusa and renaming the conceptual Medusa to Gorgon.
