Hearthstone launched a new In-Game Shop today, featuring the options to buy wild packs with gold and a cool way to see in what Hearthstone Year a expansion or adventure got published.
On December 10 visiting the new Shop will give you the alternative Hero Skin Tyrande Whisperwind for Priest, also you will be able to buy the new alternative Hero Skin Sylvanas Windrunner for Hunter for $9.99.
I myself used the new Shop to buy some good old packs with gold!
