The Spoils of Warcry (is this too greedy)

The combo:
Start out with a normal warcry line up
Turn 1: Oni Ronin or Oni Samurai
Turn 2: Crownwatch Paladin or Rakano Outlaw
Turn 3: Sower of Dissent
Turn 4: Rise to the Challenge for any combo piece
Turn 5: Navani, Warsinger and Warhelm
Afterwards you should now have zero cost weapons that will draw you through your deck with Oni Quartermaster.
Yeah, I dont know how meta the deck is and probably super greedy, but it's fun.
Comments welcomed.
