This deck is absolutely fun to play. However, i play a bit different version. I think that the inclusion of darius and mosh is not even necessary.

Darius is mostly used as a removal (but it is shining if you use it as a 1 for 2), so i think a single fiery war axe will handle the job.

Mosh is really useful in hard control matchups (cubelock and taunt druid), but generally the 4 aoe (reckless flurry and brawl) should be enough.
