Thanks for the heads up. Although I wish the card entries on the site would say where they are found/unlocked (other than "by playing Destiny") or if they are unobtainable due to glitches or are exclusive to Sony babies right now. Hard to do some Google'n to find out that the Mercury card is apparently unobtainable right now? At least, no one seems to know how to get it along with a few Places
Yeah sadly I don't think they'll add that unless they change the way they run the site since right now they just pull data from the game, no additional info for anything as far as I can see.
From what I can tell MANY places cards are glitched. I actually am going to see if the support forums already has a topic on it and if they don't I'm going to start one.
