@feelinfroggy Harpie Lady is a special type of card. There are many different types like GraveKeepers, Archfiends, Toons, etc. Harpie Ladies are just a different type of cards. Specialized decks made from certain cards like Harpies are called Archtypes. So basically a Harpie Lady is just another Archtype that they are tryin to build a deck around. Hope that helps :D
