I'll trade up to 65 USD worth of steam games, you name the game and I'll buy gift copies and send to any e-mail you'd like, for 1 hearthstone beta key. I live in the USA, so the copies I will buy will be NA copies. I'm not sure if you can use them in other countries so research that before you trade with me.

Add me on skype with a message about the HS key.
MM is an option, but depending on the cost of the MM I might have to lower my price a little bit. We can talk.
