Champion of Impulse is really good in THIS deck. Her power buff is nice, but a 3 power 4/4 is very good in the current meta. She locks a lot of common aggro attackers, dodges torch, and eats a Vanquish for your big boys. Or she just smashes alongside Dawnwalker for a very convincing clock.
Nocturnal Creeper replaces temple scribe because it hits harder, still draws (who cares about the opponent? Our cards are usually individually stronger), and can eat big dudes with Quickdraw, Aegis, or Finest Hour. And she carries Xenan Initiation better, too.
Everything else should be self-explanatory. Numbers aren't perfectly tuned but more of a fucntion of my buying legendaries to tweak for the current metagame.
I rode this from Bronze 1 to Gold 1 in a couple weeks.
