The account has every card in the game except some useless card from The Grand Tournament. You can create every deck you want. I spent most of my time and more than one thousand euros on this account, but I think that it's time to move on with my life, I need money for other projects I have. That being said, here we go with the golden count.

If you are a collector like me, or simply want to enjoy Hearthstone to its full potential, enjoying golden cards and expensive card backs, I think this is the account for you. I don't like selling it because I had many fun times with this, but as I said my priorities are changing.
I can't really put a price on this. You feel free to make your offers, or ask for any additional screenshot.
You can do it here via PM or simply reply to this thread.
