19/9 UPDATE: Final version, changed hungry crub to King Mukla.

6/9 UPDATE: Once the nerfs implemented, power level of aggo decks like pirate warrior, murloc paladin, and token druid decreases, and it is expected that it is the time for this deck to shine.

Changes made: Howlfiend replaced by Unlicensed Apothecary

14/8 UPDATE: after replacing Leeroy with Howlfiend, I reacted legend rank. Record with this deck: 3 days from rank 9 to legend 565 

Against DK Priest: 

-save alchemist for doomsayer if possible.

-buff your minions to 4 attack or/and above 5 hp to avoid dragon fire, such as Malchezaar's Imp + Bloodfury potion.

-can also buff Unlicensed Apo to big monster: being silence also eliminate the negative effect, being death can protect doomguard

-Don't worry about the Unlicensed Apo's negative effect here, because you either rush him down or lose the game, your health pool is pointless here. In some cases, I won against DK preist even I lost 15 - 20 health due to Unlicensed Apo.

-Succubus's 4 attack stats can usually deal a tons of damage in early game.

 Against Mucloc Paladin

-save soul fire in your opening hand if possible, Turn 1 a one drop minion+coin+soul fire, followed by a demon fire buff and trade in turn 2 usually win you the game.

-always clear his board, nothing left there for him to buff. You minions's overstats body can easily make a good trade against his minions

-2 ways to defend his sword: buffs and Lakkari Felhound. your 3 drops are either buffs or 5/5 minion which is good against his sword

-main ways he can come back when he lost the board:
Finja, and buff in following turn (Lakkari to defend it);
Sunkeeper(Buffs, such as: Crystal weaver buffs all to 4/4 and trade);
Skelemancer+buff in following turn(spell breaker/kill it before buff, such as using crazed alchemist on Lakkari). 

Against Jade Druid

-make sure you can pass through the spreading plague before you place minions. Unlike normal zoo deck, you can either choose more minions and discard buffs, or the other way around.

-Jade druid is one of the opponents that you are willing to put all the eggs in one basket: to buff one/two minion to a big monster early. They are quite bad at removing something like 10/9 minion in early game (only a few will run neturalize and keep it in opening hand. the only risk is spellbreaker)

-After the innervate nerfs, you can win the game before they can use their ult infection most of the time.

Against Control DK Warlock

-always make sure to buff minions to avoid defile.

-save crazed alchemist to counter possible doomsayer

-Siphon soul is their main way to deal with big minions. Apart from Jade Druid, It is another match up you are willing to buff one/two minion to a big monster early. They don't even have a effective way to deal with your King Mukla or Unlicensed Apo sometimes!

-Don't worry about the Unlicensed Apo's negative effect here, they don't have burst to kill you even you are below 10 hp

Against Zoo Warlock

-Simple. your minions body are way bigger than theirs. Your Lakkari Felhound is a nightmare for them.

-Control the board and win. Given your overstats minions, you can easily make favorable trades and control the board. They don't have ways to come back when they lost the board.

 Against Evolve Shaman

-not really good for you. Their devolve is a nightmare for this deck, and you don't really have ways to stop it. Even you controlled the board, their evolve+Dopplelgangster combo sometimes still lose you the game.

-good thing is that there are not too many evolve shaman in ranked

-save crazed alchemist to counter totem

Against Quest Mage

-saving crazed alchemist to counter doomsayer is a must, this matchup is simply about whether you can kill the doomsayer or not.

-don't worry about the King Mukla's bananas. You can finish the game when there are 15 cards remaining in his deck. Having the quest done without the full combo pieces is useless.

-go face, face, and face. face is the play
