Edit: I'm glad a lot of people enjoyed the deck. I wanted to apologize that I haven't made a guide... I just really haven't had enough time, and I'm not sure how good it is in this meta, since I played it to legend at the end of April. If anyone wants to post a guide in the comments, I'll copy it up here and obviously give you credit.
So, I rarely copy decks, but I saw Dog play this Jade rogue deck and had to try it ( I use +1 Defender of Argus and -1 Cold Blood ). I was trying tons of decks at rank 5 for fun, and when I played this one I went to rank 3 with only 2 losses... so I continued to give it a try, and in 2 days I was surprisingly at legend. Keep in mind I'm not really that good of a player, which says a lot for the deck.
The most interesting parts of this deck are Cult Master and Shadowcaster, two cards which I really like using in decks. I was skeptical of Cult Master in the deck, but it works quite well, and you will very often end up drawing at least two cards at a time.
I could go into more details and make a write-up if there is interest. The main things I can say about the deck is that it wrecks control decks. It loses pretty hard vs Quest rogue, though my legend game was actually an incredibly close one vs quest rogue... so if you can manage to put pressure on them early, then it's possible. It's actually not bad vs pirate warrior because it has early game: backstab, jade shuriken, SI-7, Mistress of Mixtures, Patches, and then it has face protection by using Argus to make small taunts that they have to waste weapon charges on. I would say that I definitely have a very positive winrate vs warrior. It has a positive record vs paladin, and I would say that the main way to beat them is to not overextend too much.
Anyway, enjoy the deck, and you can check it out on Dog's stream.
