This deck took me to rank 7 full stars in the Feburary 2017 Season, but I believe it can reach even higher, especially with the nerf to Small-Time Buccaneer.

This deck is different from other hunter decks because it utilizes uncommonly-seen cards like Knife Juggler, Snake Trap, Timber Wolf.

The Cards:

Most of this should be self-explanatory, but I'll go through the cards individually anyway.

Alleycat: Solid 1 drop with fantastic synergy with the rest of the deck.

Timber Wolf: An underrated card best saved for when you have 3 or more beasts in play. Works well with Alleycat, Snake Trap and Unleash the Hounds, or Rat Pack.

Explosive Trap: Mostly there to counter aggro pirate decks.

Kindly Grandmother: Great 2-drop for any hunter deck, but works especially well in this one. 

Knife Juggler: Still viable after being nerfed. Fantastic with Alleycat, Unleash the Hounds, and the deathrattles. If someone activates Snake Trap while this is in play, the juggles will occur before the opposing minion gets to attack. This will sometimes kill the attacking minion leaving you with your Knife Juggler still alive and three extra 1/1 Snakes. 

Quick Shot: No explanation needed. Good face damage late game or to clear problematic minions.

Scavenging Hyena: An MVP in many games. It's not difficult to buff this with all the 1/1s that you'll be summoning with this deck. Your opponent will likely try to kill it as soon as possible, so you can save a Tundra Rhino to ensure it can attack.

Snake Trap: Yet another way to put large amounts of beasts on the board.

Animal Companion: Almost an auto-include in Hunter decks. Often you will want Leokk due to the large volume of minions you will be throwing down. 

Eaglehorn Bow: Can often let you deal 9+ damage to face.

Kill Command: Amazing card for clearing taunts like Thing from Below or giving finishing burst damage.

Rat Pack: On it's own it's a good card, but the Timber Wolf and Houndmaster buffs make it a powerhouse.

Unleash the Hounds: Can be used with Timber Wolf to double the efficiency, or great for buffing Scavenging Hyena.

Houndmaster: As stated previously, best used on a Rat Pack, but overall gives you a bunch of stats for whatever you use it on, and can save you against another aggro deck.

Barnes: Alleycat and Houndmaster are the only bad targets for this card. Getting a Scavenging Hyena, Tundra Rhino, or Savannah Highmane can be game winning.

Tundra Rhino: Freely trade your deathrattles and attack with the summoned minions, and ensure that your massive Scavenging Hyena can attack.

Savannah Highmane: One of the best cards in the game, great finisher, and on curve after Tundra Rhino.

Other options:

Tracking: Not be a bad idea for finding the combo cards you need.

Freezing Trap: Can be included to help protect your high-attack low-health minions.

Cat Trick: Just a good aggro card, and can mitigate the pain of an opposing aoe.

Bear Trap: I love this card, but I removed it because it often went unactivated for the entire game.

Ragnaros the Firelord: A little slow. Had this in previously but since you won't be trading much every game he will often be unhelpful by killing minions and not SMOrcing.
