I had some free time in the afternoon, so I did a quick match in Hearthstone Beta… and whoa.. I didn’t expect things to get this crazy.

Yes that’s 23 Attack / 15 Defense on a creature. I still won though, he had only 3 health left and his creature couldn’t attack my hero. Had one taunt creature, he had to force himself to attack it, then on my turn just used Arcane Shot & Steady Shot to get the win!
