I've been watching this guys stream on twitch where he plays lots of real money poker online, he's also a professional poker player. He kinda shows that there is quite a bit of skill in poker, it's a good watch.

Although saying that I agree there is also a lot of skill in Hearthstone, its not simply playing the best cards in your hand as some people seem to believe -.- .
