This list has been getting a bit of attention on ladder. This is the Muzzy Dragon Druid Deck w Book Wyrm list that was one of the first Dragon Druid builds after the last wing of Karazan was released. Book Wyrm is a decent card, and works well in this list. Being able to innervate it out makes it a lot more playable as it destroys minions with 3 or less attack, so the longer the game goes the less value it has.
I’ve only had a chance to play a few games wth this deck, it seems really strong vs aggro which is always good at the beginning and end of the season. There are loads of other Dragon cards you can include and switch around too if you want to experiment with the list.
