I have made changes to my earlier creation because of recent nerfs and buffs. This deck performs very well in current meta. It is very fast, very spammy and never runs out of resources until your deck is empty.
The new Harpoon Gun is just beyond OP in this deck. Pack Kodo that costs 0 that give you more Harpoon Guns, two 2/3 pack mules for 0 mana. The tempo gain with this deck is just insane.
If you like it, I will write more detailed guide.
Best matchups - Rogues, other Hunters.
Worst matchups - Warlocks and Warriors
