I'm doing well with this, I think I'm 6-1 right now.
Basically you want to try to get to 10 or less health. You can achieve this using by using your dagger (Rogues are infamous for self-inflicting damage after all). Then simply play Molten Giants and smash face, returning them to your hand with Youthful Brewmaster or Shadowstep to attack again kill your opponent in one turn. Remember, if you have both Youthful Brewmaster and Shadowstep, it's better to Shadowstep the Brewmaster than the Giant to get in the extra 3 damage.
Given Rogue's plethora of removal it should not be hard to keep the board clear. Ancient Watcher is just a solid early drop to help you hold back some early rushes.
EDIT1: Added a lot more draw power.
