I just won the match vs the priestess and Ryvern early on in Culdcept 3ds (glad thats over. I hate her deck) and afterwards it advertised that something new was going on in the area where you can trade 3 cards for 2 random ones.
It now says "SALE" on that area of the menu, but when I go into that area it seems like its the same as always. Any idea what this means?
