Boundaries Crossed Gold Potion Ace Spec
I didn’t even know these ace spec cards existed until recently, but once I did I knew I needed one for my collection and picked up this Gold Potion!
I have never heard of an "Ace Spec" card. Pretty cool!
@MilesC0328 thanks! Yeah they only did them for a few sets at the end of Black & White between Boundaries Crossed and Plasma Blast, so there aren’t too many of them and probably are not well known
