For me it is better than MC.
You don't need to fill your deck with so many secrets like MC and if your don't have luck to draw MC your draws are terrible with cheap secrets in mid/late game, this new one thin your deck 2 turns early.
This is the kind of card warrior, rogue and shaman need so desesperately, good tempo and value at the same time and Blizzard give to a class already have one of more broken cards ever Call To Arms.
I never felt an expansion and meta so unbalanced like this one, what is good become better, what is bad become garbage. :(

I've normally been using Barnes to try and pull Savannah Highmane, Cult Master, or anything with deathrattle. There aren't many good 4 drops for hunter and he seemed like the best option. Maybe we could replace him. Any suggestions?

I'm still trying to figure out the best choices for this deck. I'd like to address your second question first.
I really really did try to work with 2 copies of hyena and may do so in the future. The current build I'm running of this deck was to take out one deadly shot for the second animal companion, and I also took out one kill command for an Arfus (although this deck would no longer be that cheap if I updated it). Again I'm still trying to work with this deck and may just end up sacrificing the Arfus for another Hyena. Just personal preference I guess considering that you really wouldn't want to play either card on their own (Arfus + Corpse Widow and Scavenging Hyena + sacrificing any beast). So I guess if you want to put the second Hyena then replace Kill Command.
Now for your first question, I really l couldn't find any room for Alleycat. The 1 drops are already very strong - Fiery Bat is an incredible value card for turn one and also for the turn five play of Corpse Widow since it gets discounted to 0, and Jeweled Macaw adds to more late game value. I guess Jeweled Macaw could be taken out for Alleycat, but that would make Alleycat a potential dead draw after turn 6.
Stitched Tracker is an incredible card. I know the 2/2 play on turn 3 seems incredibly weak, but I think it is just enough to carry it's value. The 2 health allows it to survive a ping so that if you really need to you can send it into your opponents minion on turn 4 with a Cult Master to draw another card. On another note, Tracker can theoretically have endless value. There have been a few games in which I never drew tracker until after turn 10. Almost every discover I could discover another Tracker, then another one and etc. The dream could be to keep putting out 2/2s that your opponent couldn't really deal with, then having the potential to give one +4/+4 Taunt with Bonemare. Tracker is incredibly flexible allowing you to draw whatever you need, whether it's card draw with Cult Master, to value with cards like Corpse Widow or Savannah Highmane.
To counter the aggro decks, you would just want to mulligan for Explosive Trap and Deathstalker Rexxar. If you do manage to draw stiched tracker, it is still just incredibly flexible to get your cards like Barnes, Houndmaster, or Fiery Bat which will take care of the aggro push.

Don't judge a deck by one days experience. You may simply be playing it wrong. I'll have the guide up on how to play it soon.
