The secret rare burning shadows energy or any of the cards that are legal because of a reprint are not standard cards on this. They should be. Will they ever be?
nah prolly not theyve got bigger fish to fry
Hey, this is a great question, this will be worked on with the architectural carddb upgrade, which will make clear distinction of which cards are reprints, which are full arts, which are secret arts, and so on. And the game will allow usage of any version of the card (as long as there is no text or type change in between, in that case we won’t allow this by choice, to make it clear for everyone to understand cards by just looking at them). Give it about 6 months for this feature to be fully implemented.
