This deck is going to be insane post nerf. I got #4 legend with it even before the August 26th nerfs. As for my opinion on the nerfs Shudderwock Quest Shaman, Myra's Aggro Rogue, and Highlander Hunter are super strong decks that didn't get touched. Also contrary to popular belief on ladder control warrior has been doing a lot worse in legend ranks then tempo warrior (at least from my experience and with decks like priest being strong still).
Anyway catch my stream at https://www.twitch.tv/kaiser_hs for more info. I explain all the card choices but here is a quick run down.
Cards You Shouldn't Play But Other Lists do.
Shimmerfly As a deathrattle not only do you not get to use the card right away but you also don't get to choose the spell either as it is random and not discover.
Sunreaver Spy Your hunter secrets costs 2 mana so curving this guy out is too hard especially because I prefer not to run snake trap. Snake is not good when your losing but all my other secrets are fine always.
Masked Contender Again our hunter secrets cost 2 mana and I prefer no snake so a lot of the time this card is simply not worth it. With mirror matches increasing as well it will also make you more susceptible to flare (both before and after it comes down).
Snake Trap For now it is one of the few traps they can simply avoid activating but that can be a good thing if you run the other secret cards I omitted above. If you really like snake cut either Snipe or Explosive Trap. In an open decklist tournament not having Explosive Trap is really sketchy though because they won't have to play around it when you bluff it (assuming the secret wasn't a "created by").
Tracking This one is most controversial. It is way worse the 2nd time around with Zul'jin meanwhile flare is amazing the second time around but with mage falling off and hunter going up in popularity soon I still prefer just one flare no tracking. If you must put it in it is honestly perfectly fine.
Super Underrated Card
The Most Overrated Card That I Play
Hyena Alpha Mostly because I don't play snake trap.

Latest Changes (Effective 8/23/19 Pre-Nerf)
I know I said that I didn't love snake but snipe and explosive are replaceable too so I felt snake was higher impact anyway and if you do go mainstream and run secret synergy cards like Masked Contender, Hyena Alpha, or Sunreaver Spy it will help you (again I still prefer 5 secrets only still especially with this build.
ALSO IF YOU READ NOTHING ELSE PLAY Wing Blast IN YOUR DECK! especially better with desert spear.
Desert Spear helps make your Animal Companion rolls better since Leokk has synergy with it. Also it is good with Kill Command giving a beast for no mana cost later on and it triggers opposing secrets as well as works with Marked Shot / Vulpera Scoundrel beast synergy discovers.
Tracking was always probably correct I was just to stubborn. Even better with less control warriors for the fatigue downside but control warrior was never an issue it is so free. Tempo warrior is a scarier match-up and the better deck anyway.
