Whoops, forgot to check back here to see if people had questions about the deck. Then, when I tried to I had internet problems -.-
Acklow Yeah, askaninjask and UltiMario stated the reasons for Stonetusk Boar. Timber Wolf isn't a bad choice and I used to run it back when Midrange Hunter was the #1 deck a few months ago, but ever since the nerf to Unleash, I just found it a bit too slow when trying to combo it with Buzzard and UTH (turn 6? but I wanna drop Highmane this turn :/ ). It's still a pretty good card, but I never ran more than 1 copy in any Hunter deck I ever played. I would definitely drop Scavenging Hyena and Emperor Cobra for a pair of Eaglehorn Bows if you have them. Some Midrange Hunters are successful without them, but they are amazing if you have any number of traps in your deck. I found I had too many cards to combo with UTH when I ran Hyena in the deck. I typically had both Buzzard and Hyena in hand on turn 5 and always had to choose which one I wanted to "go off" with (almost always picked Buzzard). That and you also have to consider that Leeroy combos with UTH as well. Cobra isn't really worth it unless you're going to run Tundra Rhino to try and get immediate value out of it. Sure they combo with Houndmaster, but a lot of times when I used to run it I found I DIDN'T want to give it Taunt because that would make it a target, especially when you need Cobra to kill something specific. Even Oasis Snapjaws would be a decent replacement.
And, yeah, I hate when I mulligan for Ramp/Midrange Druid when I queue up against them and it turns out to be Token and I'm wishing I kept that Explosive Trap/UTH :/. Token Druid is getting more popular though, so it might be worth keeping those cards against Druid now depending on how many cards they toss/keep.
Yeah, I'm not messing with second Naxx wing yet. Don't wanna lose my hard earned gold :P .
