Because I sometimes have too much time on my hands, here's a little collection of all the cards from the Basic and Classic set that borrows artwork from the WoW TCG. A lot of the original cards in Hearthstone (as well as the first two adventures -- Naxxramas and Blackrock Mountain) borrow artwork from the TCG because the team wasn't as big as it would eventually become, and it's not until the first expansion, GvG, that we would get unique artwork for nearly every card out there. Here we go! Some of these Hearthstone cards depict specific characters.
This was done because I did something similar for Book of Heroes, and decided to just go all the way.
Will primarily just talk about collectible cards and tokens created by said cards. From Rastakhan's Rumble onwards, currently there are no collectible cards that use TCG artwork.

Puzzle Labs uses all brand-new art for their adventure cards. When Battlegrounds and Duels were initially released, much of their artwork were also reused from the TCG too. For Book of Heroes, click here.
