For the tavern brawl Six-Shooter you can almost every time get a perfect curve. This means you can perfectly spend mana up to turn 6 with some powerful minions. The minions in the deck have so much value.

Dire mole was chosen as it rarely dies on the opponents turn 1 allowing it to survive and, as it is a beast, allows Crackling Razermaw to hit and gain a large tempo advantage.

Crackling Razermaw is good for controlling the board and gives immediate value in the early game and can do crazy things in the later turns.

Bearshark was chosen because it ensures your Houndmaster can hit the next turn as spells such as sap, frost bolt, jasper spellstone, naturalize ect. cannot remove the Bearshark.

It is very common to get the full value from Houndmaster because every other minion is beast, therefore Houndmaster is a 6/5 with part 2/2 charge for 4 mana. 

At this point you should be even/ahead on board and so Tundra Rhino and Savannah Highmane should push you through the enemies face.  If they somehow survived past turn 6 or 7 and don't concede. Bearshark can be buffed to get huge so aoe is not likely to remove it in the late game. Highmane provides tonnes of value and eventually with so many minions they probably cannot remove the Tundra Rhino allowing you to do crazy charge things with all the other minions.

This deck's win condition is faster than combo decks, and has much more value in terms of stats for mana against fast decks, and is super easy to play.

+I've won around 10 times with this deck, so I've played a few games and no mirrors so that's nice.
