Because I seriously remember reading some kind of interview to the HS staff where the guy said something along the line of "Dont dust your Wild card just yet! You are going to be able to use them in the upcoming mode". I cant find this quote now tho' and being myself a free to play-er and having neglected the game in favor of LoR those last months, I was thinking of dusting some old legendaries to keep up with the new cards. Dont want it to turn out to be a shitty idea when the new mode is announced, can somebody confirm this?
