First Blood

Widow's Wick

Knife Juggle

Just something to counter a turn 2 Shielded Minibot. Creation of salt? Maybe.

Masquerade

Blackmarket Sentry

This card is based of off Shado-Pan Rider. It has low on curve stats, but if you combo it, it becomes a Chillwind Yeti for 3 mana.

Dual Wield

A new idea to Hearthstone, the ability to equip two weapons, and attack with each. Could be fun to have the ability to equip both Assassin's Blade and attack with it and have a Poisoned Blade that loads up in the background... Hey!! It's called Theorycrafting...

Blade Enchantress Zevha

The buff applies only to the weapon you currently have equipped. Could work as a 4 drop in a tempo-based Rogue. A stronger Chillwind Yeti, which might actually be run now since Piloted Shredder won't be in standard.

Sen'jin Dagga' Juju

Let us solve this healing problem once and for all, aye? Well, mon, dis fine lil' juju potion' may no' solv' da probl'm fullee, bu' it will decr'ease, ya, mon.

Troll dialect aside, I think of this card to be the Power Word: Glory of Rogue. Functions quite similarly, has a combo to make it even better. Really promotes Rogues playing weapons with high durability instead of just their Hero Power. Also is a low cost spell, which is always a plus side for Rogue.

Mahnoor Snowblade

Could give Rogue a bit more survivability. Seems not too OP imo, however if I were to nerf it, then the "Talwaar" could have less durability. All in all, a Tirion-ish Rogue card that acts similar to an Ice Block combined with Gorehowl. 2complex4me

Shadowy Sentinel

An attempt at combining two different Rogue archetypes (Mech & Deathrattle), to possibly form one strong one. The Deathrattle can belong to any collectible card in the game, ranging from Haunted Creeper's to Sneed's Old Shredder's to even a board wipe on your part from Abomination. So, the RNG range is huge, and could possibly even be broken, but since your don't know what deathrattles you get, there's no literal way of playing around them.

Power "Candy"

The kind of candy your parents warned you not to eat as a kid. Strong effect at first, but you better be prepared to deal with the "side effects". Seems balanced imo. Compare it with Tinker's. Here's the side effects:

Persuade

Fun combination of Entomb and Corruption. I could not find better wording for this without it sounding weird, help appreciated.

C. Lumbus

Famous for his ability to turn small items into strong artifacts, C. Lumbus can find his way into an interesting Rogue deck with Cutpurses and Tomb Pillagers. More coins in the future means more synergy for this guy. Has good stats for the cost, because the effect is too linear to be consistent and needs prior set up.

Mafia Lady Lydia

After her failed rebellion against King Varian Wrynn, Lady Lydia needed to Conceal herself and her goons because the Stormwind Knights were looking to Execute her.

In any case, this is a Loatheb-like effect which is very much needed now that Standard is coming. 

Asha'Alor Agent

Demonic Mischief

                                                      So, what's new?

Let's start the new season by introducing the main theme around it: The Toxins. With the release of, Rogues got to see a a new and interesting weapon in their arsenal. That being, the corrosive Toxins. The Toxins are 5 1-Mana cards that are available to the player via different methods, thus far, only Xaril, Poisoned Mind. Gaze at these 1 Mana Monstrosities!

Similar to Spare Parts, these Toxins all of different effects. While some are used for helping our own selves, others can be used for inflicted damage and causing problems for the enemy. The theme that I decided to choose while making cards was to use these as "Chemicals" created in Pandaria, by the Klaxxi, namely, Xaril, Poisoned Mind. These are then shipped all round the world, causing some people to become addicted to them, while others smuggle them to sell them for profitable prices. 

One thing to keep in mind is that these Toxins are more or less used to add flavor to existing decks, rather than creating decks of their own. Being just 1-Mana spells, the Toxins themselves will not be able to create a Toxin-archetype, however combo'd with cards like Gadgetzan Auctioneerr and Malygos, these Toxins can cause the enemy player to become... well... toxic.

Something else that might tickle your fancy is some good ole' Cursing. No, not the swearing type, the evil long lost hexes type. Also, there's Dragons. Yeah. ... Just bear with me please.

       Zehn'Gen's Bucko

Your generic 2-drop to help you gain those Toxins early on. Though unlikely, it can attack multiple times, thus giving you a lot of Toxins. The stealth does allow you to get at least one. The drawback from this is that you don't get the Toxin immediately. You get it the next turn, assuming you attack with it. All in all, a pretty alright 2-drop for a Toxic deck.

Change: Stealth removed for Balance. Stats inverted.

         Toxin Addict

         Chemical Factory

Xaril alone, won't be able to handle all that much work load, considering how nuts people are over these Toxins, thus creating a Chemical Factory, doesn't sound too bad of an idea, eh? This makes it so your Toxins have more of an impact when played, however it's a 2 Mana Tempo loss when played with nothing else.

Change: Costs just 1 mana.

        Recipe for Disaster

        Black Market Vendor

         Overdosed Zombie

         Toxic Rings

         Gathering Intel

         Curse of the Silithid

   Under-King Anub'et'kan

         Curse of Blindness

         Blend

         Elite Sentry Poe

 Alright, here's another Pandarean for all those Panda-lovers out there. He's the main guard, and the most elite sentry at the Black Market. Poe's strength comes from the fact that he's has almost on curve stats, thus, by using your Hero Power, he effectively becomes Spell Damage +2. Furthermore, if you use bigger, badder weapons, then Poe's value sky-rockets! Rogue's could definitely find a use for him, I feel.

         Lil' Hatcher

         Crimson Drake

   Drakonid Spellbreaker

  Sinestra, Prime Consort

 Sinestra, the Brood Mother

She doubles spells, and doubles herself! Yup, there's two Sinestra cards. This time, she's graced her presence with her Dragon form. Again, following the theme of magic and spell-slinging, Sinestra once again comes to the board with an epic impact. She triggers the effects of 5 spells you've cast this game on your enemies. The spells can be damage-based, from Sinister Strike to Eviscerate, to a Headcrack or a simple Shiv. Since the card especially mentions "enemies" the spells must either be Damage-doing or ones that interact with minions such as Sabotage or Assassinate. Your spells like Beneath the Grounds will not work, something like Gang Up, will however. Obviously, you won't be using Gang Up or Assassinate on enemy heroes, thus you also won't be using Sinister Strike on enemy minions. If a certain spell mentions that it can only be used on heroes or minion, Sinestra, will also only trigger them on a hero or a minion. If a minion does not exist, that certain spell will simply not trigger, in which case among the 5, only the ones that can function without a minion on board, like Sabotage (breaking your opponent's weapon) will trigger. Also just to have things cleared, the this works like Anyfin Can Happen in the sense that the 5 spells need to be 5 different spells, and much like Anyfin, if you casted multiple copies of a single spell, you will once again trigger multiple effects of that one spell. As far as balance is concerned, it lines up with the other insane 9/10 mana Dragons/Old Gods. It has a pre-requisite and a strong board impact, which however, has RNG required. Requires a deck to be made for it before hand with focus on certain minion-targeting spells. It becomes nuts with Spell Damage, which I believe to be the center-point in Dragon Rogue.

Effect has been changed. I'll add a new description soon TM.
