I played a very similar build of this deck back in Descent of Dragons, and long story short, I think the biggest issues the deck had back then get in some way alleviated with the new bombshell card Secret Passage. For one, it lets cards like Counterfeit Coin and Preparation get a lot better, and overall the changes make [Hearthstone Card (Edwin Van Cleef) Not Found] a quick alternative wincon that you can just storm into. In my original builds of the deck, I was reliant on the cards Brann Bronzebeard and Spirit of the Shark to double up the ETB effects, but with the speed of Passage and the fast mana available, you might not need them. Skyvateer is currently a flex slot, just until I can see how good Praise Galakrond! is with/without it. You also don't want a lot of clunky costed cards in the deck, which is why Vanish isn't currently included, and why I'm not sure if Brann or the Spirit can fit yet, so having cheap minions with good value like Skyvateer becomes a little more important.

Assuming they don't nerf Passage to oblivion, I'll probably continue working on this deck as time goes by. It's been a lot of fun in the past and I think there's a lot more coming to Rogue that lets this deck get more ways to be built.
