This deck and guide are a few months old. I am busy with school, so I don't know how this would fare in the current meta. Feel free to leave me a question, but it might be a day before I am able to respond.

THE GUIDE

"Guide" is a difficult way to explain this. Using the word "Guide", it is assumed I'll give you every bit of knowledge you'll need in order to master this deck. Unfortunately, I can't predict every situation or opposing deck, so don't see this as an official list of rules, simply play the way you believe is right.

Jade Rogue is nothing complex. It's just Tempo Rogue of yesteryear replaced with a few new released cards in order to give you a second win condition: Jade Golem. As such, try playing for Tempo as often as you can, with the exception of a few cards. Even if you can't combo with your Jade Shuriken, if it gives you board control, use it. Never play a card "because you can". Think about why you're playing it, and if you're playing it for Tempo of Value. Unless you're ahead on the board, play for Tempo. Of course, I can't predict every situation so value could be the right play. I'll leave that to your own jurusdiction.

In terms of card draw, this deck has very little because each card has enough impact on it's own there shouldn't be a need for much. Swashburglar, Undercity Huckster, and Bloodmage Thalnos are all ways you can garner new cards. Try to use your cards more conservatively; if you play your entire hand to deal with one minion you WILL lose.

THE MULLIGAN

Always keep: Undercity Huckster, Swashburglar, Jade Shuriken,  Jade Swarmer, Backstab, Small-Time Buccaneer.

With coin: SI:7 Agent, Tomb Pillager.

Against Aggro: Fan of Knives, Eviscerate.

Additionally, keepSI:7 Agent if you haveBackstab regardless if you have the coin or not.

THE CARDS

Backstab: The best tempo card in the game. Also a great combo starter.

Swashburglar: An amazing one drop. This is one of our "value" cards that's too good to leave out.

Bloodmage Thalnos: He's really, really good. Need a little bit more out of your Fan of Knives? He's got you covered. Card draw? He's got that too. N'zoth even brings him back!

Eviscerate: This card should almost always be comboed. A better contender for 2 mana 2 damage would be [card]Jade Shuriken[card].

Jade Swarmer: It's supposed to die. That's really it.

Jade Shuriken: Don't worry too much about getting a Golem from this card, but it's always a nice option if available.

Sap: Soft removal at a nice price. Taunt in the way? Sap it. A buffed minion? Sap it. The bigger target you can get, the better, as it causes them to spend more mana for a resummon.

Undercity Huckster: Probably the best turn two play. Great synergy with N'zoth, and more often than not gives you a good card along with board presence.

Fan of Knives: R.I.P Blade Flurry. This is the next best thing we have for AoE. Wonderful if you can combo it with Azure Drake or Bloodmage Thalnos.

SI:7 Agent: If you have the coin, keep this guy in your hand during the mulligan. Turn two coin into SI is devastating if you can take a minion with you.

Unearthed Raptor: Don't be afraid to drop this even if you don't get a Deathrattle effect. It's body is solid on it's own for the mana cost.

Jade Spirit: Good value once you start summoning 2/2 golems or above.

Tomb Pillager: The coin dropped from this minion is fantastic for activating comboes or bringing out N'zoth one turn early.

Azure Drake: Instand draw, Spell Damage, and a decent body. There's a reason this is one of the most included cards in all Hearthstone decks.

Lotus Agents: This is probably the most controversial card in the deck. Yes, I do believe that Grimestreet Informant and Kabal Courier are much better cards, but being able to access the very strong Shaman and Druid cards is too much of a temptation to pass up. Jade Idol is one of the best cards you can pull.

Aya Blackpaw: The best Jade Golem card in the game. The stats are superb, not to mention your ability to revive her with N'zoth.

N'Zoth, the Corruptor: Your win condition. Only play N'zoth if you have at least two high-value deathrattle minions dead (Aya, Pillager, etc.)

Why the decision to remove Sylvanas Windrunner? It's more of a preferential thing, honestly. The value and potential from Lotus Agents gave me more wins overall, but she does create a scary board and have Deathrattle synergy. Use whichever you prefer.
