Hearthpwn

This is a super fun deck that has got me to diamond one. Insane amounts of value from Guidance, Emerald Explorer, Crystalsong, Kiri and not to mention Ysera. Been having a lot of success with it and more importantly a ton of fun. CAN BEAT META DECKS EASY (expect for argo rogue and Pally, those are the worst matchups, but still winable). 

TIPS:

• Try and keep a dragon in mulligan for breath, other than that you want guidance, nature studies, overgrowth, rising winds and in most cases swipe. (i don't recommend keeping gidra, he is better later on). 
• use your solar eclipse wisely, as much as solar into cenarion ward is probably the best play, think of other options such as solar into a corrupted moontouch for a nice 8 damage and 12 armor. 
• Save your greygouh for a turn where you draw dream portals, if you can manage to get 2 or three dragons on board and drop greybough its really hard to deal with, either that or use him with a double rising winds + free umbral owls. 
• miracle, miracle miracle. This deck is all about discovering good cards and outwitting your opponent, you can find lethal quicker than you think if you play right, also you can easliy out tempo control decks with some nice value plays.
