I'm glad to see Blizzard having fun with their e-mails xD
Greetings to you, Egg!
Krizgut, our goblin inventory manager, has retrieved your recently-purchased Hearthstone card packs from his secret stash, hidden deep within our sealed vaults. Not a soul can say exactly what cards you'll find inside. Will there be an Epic? Maybe a Legendary? We can't wait to find out!
Krizgut thanks you for your purchase and would like you to know that the teleportation process for your packs went smoothly, and they have rematerialized under your Hearthstone account. Time to open them up! Just launch Hearthstone, and tap the Open Packs button in your Hearthstone box.
Great luck to you in your duels, champion!
