Hearthpwn

Currently 11-3 with this deck in low legend. The combination of Magatha, Bane of Music and Sky Mother Aviana makes it so that you have a back-up if your rheastasza gets reno'ed (its also just a super fun combo). Sometimes you have a dead draw and e.t.c into  Harth Stonebrew can literally win games

The zilliax is just perfect module + copy. You have Origami Dragon and yogg for single target removal. 

Same typical druid mulligan, look for all your ramp cards (i even keep doomkin and crystall cluster except against aggro). Always keep reno if you have ramp in my opinion, unless youre against control/slower deck then never keep reno. and yeah thats it, the deck curves out smoothly and has a lot of good tempo plays before it gets to its late game value engines

Now to be fair in a lot of these games ive been lucky enough to draw reno when i needed him. So might be best to keep him regardless if you know they a board centric deck 

Other than that theres a ton of value in this deck and a lot of fun outcomes. Definitely recommend. 

Another thing to note: nerfs are going to happen, and said nerfs will 100% target this decks worst matcups  (paladin and hunter), so i predict this deck will become popular and even better post patch
