This is no longer necessary.
Beta Keys for Hearthstone stuff, it's old now.
Blizzard are giving everyone keys, wait maximum 2 days after signing up. They promised EVERYONE to get.
So, Hearthstone Beta Key is not even worth $1 anylonger.
Not trashing your Thread, but letting people know of the new changes to Hearthstone and how easy it is to get the keys now.
Hearthstone will soon be either on Open Beta (It's on Closed Beta right now) or fully Released.
No longer necessary. =3
