"Leaf Us Alone" achievement deck that will grant you total of 735XP for completing all 3 stages.
Summon 20/100/200 Greybough's
10/10/20 Achievement points
Remember all achievements must be completed in ranked or duels.
This deck has NO win condition so only use it if you don't care about your wild ranking or if you have reached your desired wild rank.
This is something I quickly build for this achievement and it turned out to work pretty well so I thought I shared this deck and do a little write up since this achievement was skipped in the excellent SirJohn13's (almost) complete guide to the achievements that offer XP
Always try to get Greybough in your starting hand! Other good cards to have at start of the game are the mana ramping cards.
I completed this achievement within 4 games but I was pretty lucky getting Greybough in my starting hand twice and running into opponents who managed to get their own Greybough copies (first opponent by Faceless Manipulator obtained by Zephrys the Great and the other opponent by Mind Control Tech). I actually believe both opponents were aware that I was going for the achievement and they got a pretty good amount of Greybough summons for there own achievement just by keeping the game going so it was a win-win.
To keep the game going and summon as much Greybough copies as possible it's important to avoid hitting face. Just try and keep the board clear until you are able to put Greybough on the board while ensuring he gets in to the pool from Da Undatakah,Hadronox and N'Zoth, the Corruptor by using Naturalize or Carnivorous Cube or combo both when possible! Unless you have Flobbidinous Floop in hand when playing Greybough then you can take a risk and maybe setup for a better combo next round.
It's certainly not necessary to have Da Undatakah,Hadronox and N'Zoth, the Corruptor in this deck since these cards were sitting in my hand most of the time when my board was already filled with Greybough's but I would suggest at least keeping N'Zoth, the Corruptor in case your opponent has Mass Dispel or Plague of Death. If you don't own Da Undatakah / Hadronox you can replace those for something that allows you to return N'Zoth, the Corruptor to your hand or shuffle him in to your deck.
I don't think Guess the Weight is a necessary card in this deck but I needed to guess the weight right for the achievement "RIGGED!" (Guess the Weight correctly 10 times) and it offered me pretty good card draw especially when combined with Solar Eclipse so if you have the card you could include it.
Replays of 2 games where I estimate I summoned roughly +- 140 Greybough's
