In the Shop it says that the classic packs can only be used in the new mode. Wrong they Be available in wild also?
I haven’t quite followed all the news recently
They will be usable in both wild and classic. The catch is that the classic version of the cards with the classic stats will only be usable in classic. The later revised/nerfed/buffed versions of the cards will be usable in wild.
I just asked me the same question and even on the official site it says "20 Classic packs and 2 random Classic Legendary cards, usable in Wild format and the new Classic format."
So as Ghostfeint said, you can use each card you get there in Classic AND Wild. The Wild-version might be a little bit different, if the card was nerfed in the past, but you get the cards for both modes.
I have no idea why the GM responded to my Ticket saying they are for Classic only and wont be useable in wild.. After digging for a while I found some stuff on their site and I also went to the Blizzard store like Master_edd said and it seems our cards are useable in wild and then mirror over to Classic format. I've found comments and posts all over with people confused because in the Hearthstone game itself it says they are ONLY useable in classic format. Maybe they need to change that because its confusing people and probably losing them sales.
