Hearthpwn

This shuffles Msshi'fn Prime into your deck.

Once you play him, you get to choose between Msshi'fn Pro'tec and Msshi'fn At'tac

which summon Fungal Guardian and Fungal Bruiser, respectively.

But most importantly, If you have Fandral Staghelm or Ossirian Tear, you get Fungal Gargantuan, where Msshi'fn Stri'kbak

this card summoning effect and cuteness wanna makes me craft it so bad

Love it. Great card even unrelated to any specific deck, but also helps bind my old wild quest druid (Jungle Giants) deck together.

In German, the name of this guy sounds like "Muss schiffen" which translates as "Need to pee". Just sayin'... :D

Msshifn-prime 

 Msshi'fn at'tac,

Msshi'fn pro'tec,

But sadly, it probably won't bring quest druid bac.

 This is NUTS. It will be in every single quest druid forever. Unparalleled value with choose both.... 

Pretty solid. Deathrattle seems alright. When you use Embiggen, this bad boy becomes a beefy 4 Mana 5/6 with Taunt. If paired with the Prime later, 10 Mana 11/11 with Taunt which can survive with sliver amount of HP if bumped w/ Kargath Prime.

Edit: On second thought, 10 Mana sure is too heavy when the others are around 6~8, and obviously it can be unplayable when drawn too early. So maybe not much of a must-have.

Edit: There are some scenarios I'm thinking. When you complete the Untapped Potential, Msshi'fn Prime will automatically summon a 9/9 minion with Taunt and Rush. It's good in most situations, but the Fungal Giant's Taunt sometimes can make itself vulnerable to attacks. Take Kargath Prime for example. In this case, Embiggen or not, your opponent kills a 9/9 and gains 10 Armor. However if you only use Embiggen, you may choose not to have Taunt, hopefully protecting your Fungal Giant with 11/11 Msshi'fn Prime, if you've applied +2/+2 to him. In this case, Kargath Prime alone probably can't get rid of any minion on your board. 

The prime art is just awful.

Nah, I think he still looks adorable.

Based on the wording I’d say one 9/9 with rush and taunt.

Now the real question... In quest druid do you get one 9/9 with both taunt and rush or two 9/9's, one with rush and the other with taunt?

it says "give it taunt or rush" so u get one with both effects
