After the new expansion, dragons are a regular pick in the draft. You can get around 7 dragons out of 30 on average, more if you go all-the-way and ignore better cards.
Most dragons are awsome picks, so I am inclined to almost blindy select every dragon that is offered. Obviously, with curve etc. you shouldn't be too blindly selecting, but what is the downside?
I've noticed a single counter to dragons in the shape of Dragonmaw Poacher, but that's the only counter available right? The Dragonslayer just rotated out, since Kobolds and Catacombs isnt' included anymore.

Other 'general' removal isn't too prevalent either right? That's based on just a few games though.

Are dragons overpowered in this game mode?
