I appreciate your feedback, I would love to put Trade Prince in here, unfortunately I don't have him. Maybe he can replace Nefarian. I just started amassing way more wins with this deck than I ever thought so I thought I would post it and work on it.

 I actually tried something like this myself except I used 1 Sideshow Spelleater with 1 Grand Crusader.

I found Nefarian to be a dead card a lot. I frequently had better combo options in my hand and didn't want to spend the 9 mana for him.

Also, Nefarian and Burgle plus 1 Sprint do not make up for the lack of standard card draw. You still have to be able to get at your cards, especially if you get trash from Burgle or Nefarian.

I think Trade Prince Gallwix has a place here too as he is sort of the quintessential card for taking your opponent's spells but I stupidly dusted him so I didn't get to try it.

I also ran Beneath the Grounds because it stole the safety of my opponent's draw and that actually turned out to be fairly effective.

This deck also can get wrecked by aggro because if you don't have Blade Flurry in hand when they fill the board, there's no other way out.

I admit that my list was different enough that your build may be more effective than mine ever was. I'm just offering my experiences.

Overall, my experience is that the concept is fun but it just doesn't work in practice.
