This is a confused thief rogue i think, the idea is good but Augmented Elekk is not too neccessary i think, this is a slow deck so The Darkness MIGHT work, but i would put vanish instead, i failed too see the purpose of Witchwood Piper, if you were to put Pogo-Hopper and use the Lab Recruiter on them then use the Witchwood Piper to draw them, then it would be excellent synergy IMO.

Thanks for the feedback.
What do you think of Shadowstep and Baleful Banker? And what cards to replace for them? 

As i stated before Augmented Elekk is not too necessary, IMO, and you don't want to play around one card too much, so my preposition would be take out both Augmented Elekk and put one Shadowstep and a Prince Keleseth, - Prince Keleseth is to be used after you put 3 Pogo-Hopper in your deck, just like Stonetusk Boar and Dire Frenzy combo of Emeriss Hunter, also i think Tess Greymane is too slow for this deck even though Academic Espionage synergies well with it, if you think of it as a Miracle/Aggro deck i would say remove Tess Greymane and one Academic Espionage to add two Cold Bloods, i know i am proposing too much change but, while the idea is great, you can't have everything in one deck, thief rogue will be relevant in the next expansion i suppose but this as you too claim is a miracle deck.
