Monk is a very interesting class to me. I've played with my Gnome Mistweaver Monk in WoW for about one year, so all the cards I designed are mainly based on my understanding of this class in WoW.
I suppose Chi is the key for a monk, so I introduced this concept to this class and hope it to be a fascinating characteristic.
The second thought is about Taunt. Monk may have a plenty of minions with Taunt but with reflectively low Attack. Low Attack can be buffed with Chi and abilities, so these minions won't be so useless in game. Also, I'm going to design some interesting cards to restore heath to minions with Taunt, therefore they could be more powerful once you have other supportive minions on broad.
Hero: Chen Stormstout
Hero Power: Meditation
* Chi can be restored over turns, but with a limitation of 5. It's a second resource for monk besides mana.
