I found something that everyone missed - midrange decks DON'T rely on tempo, tempo decks do. Midrange decks rely on strong cards being able to be played without you having tempo on the board. As someone who played a ton of midrange druid pre-wrath, I can say that until around turn 4-5 you weren't getting any tempo and your best play was wild growth on 2 into keeper of the grove/piloted shredder into druid of the claw, and that rarely happened. You don't rely on tempo in midrange - you rely on value and pressure. Duskbringer is one of the best value cards that fits in midrange, and saying it isn't good is like saying dr. boom isn't good.

 I'd suggest you remove enforcer and protector as they are too slow, while adding 2 coldlight seers for the +2 hp. Also, I'd switch a blessing of kings for a blessing of might, and hand of protection for basically anything (the closest card to it is selfless hero or seal of champions)

As for the opening hand, try for a finley and tidecaller, maybe an outfitter and chum or something like that.

 I think that darnassus is way too weak in this deck. I'd say put in 2nd roots or Wild Growth. I'd also cut defenders for growth/roots/azures.

Preparation deserves a nerf, and Master of Disguise prob needs a rework. I wouldn't change other cards though.
