I have 2 copies of Goldspan Dragon in my collection but I am unable to add both of them when making a deck. I can only add 1. When I try to add the other, despite it showing that I own the second copy, it then says my deck needs additional mythic wildcards and locks my deck from being used in duels. Oddly, it doesnt "gray out" the second GD when I add it to my deck like it normally does when you add cards you dont own in deckbuilder.
