This is a greedy version of jade druid with no plague and both medivh and kun! (PogChamp)

I wanted to make a list that mainly beats jade druid, big- and highlander priest and temporouge since they make up about 80% of the ladder after rank 5. I am currently 5-0 with the deck, but are still tweaking it. I thought it would struggle against rouge but I actually won three of the games against them :) Golakka is insane here!

I will update the deck regularly, and would love an upvote if you liked it! :)
Will make mulligan guide if the deck gets some attention. (10 upvotes)

Wow. I didn't expect so much attention to the deck, thanks, guys! Here is as I promised a mulligan guide for the most common matchups. If the deck reached 25 upvotes I will do a card selection and possible replacements guide! 

Changes I have made on the original deck: Medivh OUT, Primordial Drake IN. Its nice with another taunt against aggroclasses and the deck is already greedy enough to win control matchups :)

Highlander Priest: Wild Growth, Jade Blossom, Mire Keeper, Aya Blackpaw. If you have another ramp it can be good to keep nourish, but I think it is too slow to keep in your mulligan alone. Fandral + Nourish is also worth keeping since priests only have one pain and surprisingly often struggles with the fandral.
You have two goals this game. Fast ramp and get your jades rolling! 
By my experience, you never go infinity jades, so I always just play the second jade idol as a tempo swing. If you play around board clears your deck should be greedy enough to pull out the win if he doesn't have early pressure, Raza on 5, DK 8 and SUBS to RNGsus!

Tempo Rouge: Wild Growth, Jade Blossom, Jade Idol, Wrath, Swipe, Jade Spirit and Golakka Crawler(!)
You want all your early game in this matchup, we win the late game 99/100 times if we survive. Use your Golakka smart! If you don't use it on Swashburgler on 1 they often think you dont have it and you can eat a Southsea captain instead :)
If you meet a lot of rouges you can add doomsayer or drake instead of medivh.

Jade Druid: Wild Growth, Jade Blossom, Mire Keeper, Nourish and Aya Blackpaw.
Keep more jade cards if you already have some ramp already, this matchup is all about getting the jades on steroids first.

We are super favorable in this matchup with all our greediness! We have much better topdecks late-game and play double MCT. They are insane in this matchup and can turn a losing game in your favor!

Hunter: Wild Growth, Jade Blossom, Jade Idol, Wrath, Swipe, Jade Spirit
Very tough matchup for us. We need all the early game we can get here. The way to win is either getting 3/3 jades and bigger quite early or get some sweet swipe value. Always mulligan as if it is facehunter! If it is more of a midrange version we win anyway :)

Evolve Shaman: Same as hunter + golakka.
I have not met many shamans, but they are all about the board. Trade everything, it might get evolved 2-3 times with DK, heropower and evolves. If you get ahead on board you win. Golakka Crawler is a keep here and can give you an early advantage if he plays corsair turn 1. If not, dont hesitate to play it naked just to easier trade of his totems, fire flies etc.

These are the main decks on the Rank 5 - Legend ladder if you want any more matchups just ask in chat. Feel free to comment and talk with me in the comments about the deck, I will be active!

WOW, we made it to the front page boys! Thank you so much for all the views, comments and upvotes. I hope you find the deck fun to play and make a successful climb with it! :)
First of all, I apologize for not being as active lately as I use to, but I have had a lot to do. I hope I have cached up with all the comments but if I haven't, don't hesitate by asking again.

Card changes: 
-1 Primordial Drake | +1 Medivh  (Mainly since I have added two taunts in Bonemare and Plague, but I am still not sure who is best. What do you guys think?)
-1 Mire Keeper | +1  Spreading plague
-1 Mind Control Tech | +1 Bonemare

I will make a card selection and possible replacement guide later today. Feel free to comment and talk with me in the comments about the deck, I will be active!
