LEGEND Game Difficulty: Hardest with Graphics Bug - Galakrond

My most interesting Hearthstone achievement: reaching legend  without seeing the cards in my hand. Won 13 games. Lost only once to rogue. 

Let me define the bug first. I have an old laptop which was running the game perfectly till... With 15.4 update my regular cards become black. Golden cards are visible (in this deck Shield Block, Snip-Snap and Kor'kron Elite). The card names are not visible in any of them. I wrote a bug report on the official forums. I got typical tech support answers. No developers answered.

2684 is the correct one by the way. 

My point is: This deck is so easy to play. It should be nerfed.
