Thank @Ixlid for inspiration on Linecracker combo. His deck: https://www.hearthpwn.com/decks/1287052-theorycraft-infinite-armor-druid#c7

The primary goal of this deck is to cycle through your deck as quickly as possible to assemble all the combo pieces: Linecracker, BEEEES!!!*2, Floop's Glorious Gloop, one Earthen Scales and any of the following:

1. Innervate

2. Biology Project

3. Poison Seeds while there are at least 5 minions on the board

4. a minion on board that can be killed with no mana (either your own minion, or an enemy minion killed by Moonfire or Pounce)

You start by playing Floop's Glorious Gloop and then either Innervate, Biology Project or whatever to get back to 10 mana. Then play Linecracker, double BEEEES!!! on it, and finally Earthen Scales on your 1280 attack monster for 1281 sweet armor. If you manage to keep your second Earthen Scales, you can just use it again for 1282 more armor.

Does 1281 armor win you the game? Let's do a calculation. Suppose that you are facing a Big Priest with a full board of large minions. Let's just say 7 giants. That's 56 attack on board. If you simply AFK and don't gain any more armor, they need about 23 turns to kill you, and if by then they still have 10 cards left in deck, that's 13 turns of fatigue damage they need to take (total of 91 damage), while you can simply play your Jade Idol and summon some green men to avoid fatigue. Virtually no other opponent can get more total attack down on their board (especially for quest mage: you want two extra turns? Give you 30 extra turns and let's see who dies first), so 1281 armor does win you the game.

You may think: don't joke, that's a 6-card combo. If you could hoard those in hand while not dying, why don't you just play the Mecha'thun combo or even the Hakkar/Togwaggle combo to actually KILL the opponent?

There are many reasons. First, both Mecha'thun and Hakkar strategies can be somewhat played around by opponent. For Mecha'thun, you have to play all your cards, which means you need to find a way to kill your own Auctioneers and Acolyte of Pains. Often times if both spellstones are gone this can cost you a lot of fatigue damage to achieve if your opponent simply maintain an empty board or use freeze effects on your last Auctioneer. For Hakkar strategy, you opponent can maintain 9 cards in hand, making it harder for you to close out the game.

Second, the combo pieces don't have to be played together. In fact, they are not needed to win the majority of games. In many games, you can simply use one BEEEES!!! on Linecracker and Earthen Scales it for 81 instant armor, which can often buy you several turns (yes that's 11 mana but you have so many cards to help you get there). Later you can close out the game by using Auctioneer and Jade Idol to quickly summon a green men army. If you determine you are going to use Auctioneer + Jade to win anyway, you can even use your BEEEES!!! to remove opponent's threats early on. Also, if you are betting that your opponent can't remove your Linecracker in one turn, don't forget that if this dude stands for one turn, your brutal BEEEES!!! are gonna turn it into a 80 attack monster to instantly kill your opponent. Again, if this plan fails you still have the Jades. The flexibility of this deck is unparalleled by any combo Druid archetypes we have previously seen.

I know @Ixlid and many may want to build the deck in other ways, such as using the Jade Druid control shell to support the combo and/or using Dreampetal Florist to ensure the full thousand-armor combo. Double infestations, single infestation, double Linecrackers - I've tried all of those deck-building strategies at rank 5 (by using Mark of Natures as placeholders for BEEEES!!! and concede when I have the thousand-armor combo in hand). In my experience, I almost never had the breath room to play Dreampetal Florist, and Ultimate Infestation is very, very clunky (if you only bring one, the rate of drawing it is too low). Eventually I decided to go with the Auctioneer package, and it just feels much better.

I had the feeling that this will at least make Tier 2 (about the same power level as conventional Jade Druid). We'll find out.
