Just testing out what an updated stealth rogue might look like in FitB. 

Notable changes: 

• Dropped Cutting Class under the assumption that Silverleaf Poison can safely replace it as it has so many poison synergies, may generate more cards in the long run, and is often cheaper than Cutting Class.
• Running only one copy of Sneaky Delinquent to fit in more poisons and one copy of Swinetusk Shank. Seems like one shank is probably sufficient give its effect.
• Replacing Southsea Deckhand with Efficient Octo-bot for that 2-mana Emperor Thaurissan goodness since charge is dead.
• No more Eviscerate. We replace with more poisons.
