The option to use Japanese cards in an english deck.

I was “lucky” enough to get the Japanese Final Fantasy signiture spells Secret Lair. At the time I was able to add them to my collection, but now when I make a new deck, or try to add the versions of the cards I own, I cannot. I’d like to be able to add them again.

Even searching from my collection in the add card function results in a blank results screen.
