If you want to quickly defeat your opponent and control the board, then this Tempo Hunter is exactly what you want.
Dragon Tempo Hunter is built around two synergies: dragons and minions with Rush. The latter will help you control the board; dragons will give you the power needed to finish the game.
The new Stormhammer weapon is amazing for this list. It will likely never lose its charge, but if that does happen, you have two copies of it in your deck. In addition to Stormhammer, you have the Corrosive Breath spell. Corrosive Breath will make optimal use of your attacks.
Lastly, Dwarven Sharpshooter lets your hero power control the board. The ability is a really nice way of dealing with smaller minions in the early game.
