Glad you enjoyed playing it :-), ysera really is a strong finisher in these lists 

Iam wondering in what situations do you use Malfurion? If you got guff, would you ever change to malfurion? 

It is matchup dependent on which hero card you want to end up with at the end, Malfurion the Pestilent is in the deck because it helps a lot with sustaining your life total over the course of the game. I find my self frequently playing him after Wildheart Guff to help me gain +3 armor each turn after sustaining against decks like Pirate Warrior or Odd hunter.  The +3 attack is also useful for dealing with minions and pressuring their life total every turn. It may seem awkward to be running two hero cards in the same list but Guff and Malfurion don't require prior setup and are always going to be playable cards. 

Having two hero cards in the deck makes sure you're able to draw at least one throughout the game.  Not every matchup requires the draw a card every turn that guff provides and simply just uncapping your mana with guff while ramping, drawing a card and gaining 5 armor is good enough for the net 4 mana investment you put into him.  Moving on to having a +3 HP gain each turn with a swing of 5 armor and two scarabs IS relevant enough to justify running both as they both play out very well together in practice, and is why I continue to run both. 

Thank you for this awesome deck. Hoping to publish a video on it soon :-)

Awesome to hear, I'll check it out when you have it up :-).  This list is still holding very strong for me climbing the legend ladder, maintaining a 70% winrate @ 61-26.  The only changes I've made is experimenting with swapping Overgrowth with Biology Project which has felt great especially with guff.  

Bro this Deck is so fucking cool, by now i'm 11-5 and loving it Ty OP for the list.

Glad you're enjoying it!  it feels VERY strong in this meta right now

Thanks for this. Jade is one of my favorite archetypes in Hearthstone. I played maybe 5 games with this deck (so not too many), almost all mages. A couple things:

1. Spreading Plague, Overflow, Poison Seeds, and Floops always seemed like dead cards to me. I'm obviously playing it wrong, but any tips would be appreciated.
2. No Jade Blossom or Aya? I was surprised.
3. I don't have Mutanus nor Guff, but I do have 1600 dust to craft one. Thoughts?

Appreciate it again. Will have fun playing this.

Mage is going to be one of your worst matchups since there is a lot of turn 6/7/8 uninteractive OTKs going on with that class. with the exception of secret mage. 

1. Spreading Plague and Poison Seeds are two of the most important stall tools in slower druid lists.  I would argue without these two cards the deck and class in a control context would be unplayable (however in your case so far, they are dead cards against mage).  These are cards that will tend to sit in your hand, they require the right timing. 

Overflow is extremely important for constantly having a full hand and getting through your deck and is a pay off for spending your early turns ramping, Floop's Glorious Gloop is in the deck specifically to allow you to cast it after comboing with Poison Seeds. 

Floop's Glorious Gloop is intended to be combo'd with Poison Seeds / Starfall to combo a board wipe for free to allow for a follow up of your hero cards, Ysera, Unleashed, Overflow, or Spreading Plague on the same turn as wiping the board. It gives you the mana cheat necessary to pull out your expensive cards on the same turn you wipe boards.

2.  Jade Blossom is just too low impact when compared to Overgrowth and is not worth the card slot.  Nature Studies just does the job better as a third and fourth "ramp" spell.  We aren't actually focusing on jades until we hit fatigue in the end game and Aya Blackpaw is simply too slow to be thrown out for 6 mana.

3.  If you're going to spend 1600 dust on any deck, make sure you 100% want to be committed to playing it, it would be a waste to spend 1600 dust on a card like Wildheart Guff then end up not playing druid a week after crafting it.  With that being said, Mutanus the Devourer is a card that is safer to craft since it sees play in a wider variety of decks in both standard and wild.  Wildheart Guff is extremely powerful in this architype and is a staple in my opinion moving forward.  Mutanus the Devourer is simply tech that can be slotted for another card while Wildheart Guff will be stronger in the deck overall as a must have staple.  I would hold off on crafting either until you're confident this is something you would like to commit to, I hope this helped and am willing to answer any more questions. 

Thanks SO MUCH for your detailed response. I'll take your thoughts and suggestions into account and keep trying this deck. Appreciate it again. :)
