Customize Hero Card Pictures

Just a thought, Maybe it could be added some time after release if it's to late, But I think it would be cool if you added the ability for people to customize their hero card picture. Similar to the character customization in Wow... but in 2D.

This would also be a good idea as a way to identify different decks other than just the name.

i.e.: I make the Gnome mage deck as mainly used for quick early game with some late game stuff in it, and a Orc mage deck with few minions and lots of spells.. or something :)
