Some time ago Blizz announced three new cards in Classic, to make up for HoF class cards (Mage common and epic and Rogue common). Since the announcement, I was keeping my classic packs unopenned, since I have all commons and a large epic collection and with the new ones there is a larger chance I get something I don´t own.
Last week, they nerfed Mana Wyrm, and now I am facing a dilema: do I open the 11 packs now to have extra dust from any wyrms oppened or keep them until next week for the possibility of new cards? Anyone knows how long do nerfed cards keep giving full value? I know its a VERY marginal question, but I am just curious.
