 EDIT: It's been awhile since I've visited this deck and I know there were some people really interested in the archetype at the time. I really wanted to make a deck that used Leeching Poison properly and was unable to fulfill that with this deck. However, with the addition of Kingsbane, I feel like Leeching finally has some relevance. The dream is to get a big Kingsbane but this deck can get along well and stall even without. Previous comments about choices still apply but I've edited the weapon section to make more sense.

Included Pirates

This deck is not meant to be an aggro deck despite the inclusion of pirates. Each of the pirates provides a different, specific role:

Swashburglar: Here primarily to provide an early body while giving a stolen card. Also used as Golakka Crawler bait.

Patches the Pirate: Deck thinner with the bonus of giving a 1/1 to charge with. Not essential to the deck but a good addition.

Naga Corsair: Aggressive body that helps buff your dagger to trade or get closer to Luckydo.

Captain Greenskin: The extra charge on weapons is very very nice and the extra attack combos well with Naga to get closer to Luckydo

Luckydo Buccaneer: Insanely strong card that is often unexpected and can close out games. Most people will blow removal on Nagas, Greenskin or Peddler, leaving you open to make big plays with this. Very easy to get buffed up.

Non-Included Pirates

Southsea Squidface: Although this gives a fantastic buff and I have included it in previous weapon buff decks, it's too hard to set up properly and has worse stats than Corsair. The one extra damage isn't worth the trouble IMO.

Southsea Deckhand, Southsea Captain, Dread Corsair, Bloodsail Raider: These are all fantastic cards that I have included in the past and would include in an aggro version or one that is more pirate focused. However, they all are either far too easy to remove and/or have negligible effects. I've had way too many issues with running out of cards with pirate decks and including tons of cheap pirates runs you out of cards very quickly.

Runeforge Haunter: Not a pirate, but definitely pirate-like in that it affects your weapon. I'm on the edge for this card still. It's definitely an awesome effect but the body is not as good as Naga Corsair or Freebooter making it hard to justify including this over them.

Phantom Freebooter: A tough choice to kick to the curb but far too weapon dependent and often with far too low health to stay a threat.

Thief Cards

I've essentially included every thief card available to rogue. There's some other ones that are a bit more obscure (new Elise, Lotus Agents) since they're either too slow or don't guarantee a non-rogue card. You could use Shadowstep or Mimic Pod to generate more but it seems to situational or slow to do so. Ethereal Peddler is a phenomenal card because it not only has vanilla defensive stats but also has a high value effect.

Weapons and Spells

With the new game-changing addition of Cavern Shinyfinder and Kingsbane, we have an extremely high chance of getting an early Kingsbane and abusing weapon buffs plus Leeching Poison. All other weapons are bad compared to this one and adding more dilutes the pool with Shinyfinder. Yes, if you get unlucky, you won't draw it and you'll draw buff cards, but you're always welcome to blow some buffs on your daggers.

Why Leeching Poison?

This deck is a midrange deck meant to wipe out small threats and drop our own big ones with tempo moves using weapons and combos. Then we use our weapons and minions to close out the game before big control decks start getting their pieces together. Most midrange decks do not feature huge healing so why should this one?

Rogue is unique in that the class hits things with its face all the time to gain tempo (it has the best hero power for tempo) but has no healing sources. So unlike other midrange decks that can contest the board at a safe health total, if rogues want a board advantage, they have to lower their health, making them susceptible to aggro charge and burn spells. Leeching Poison is here for the sole purpose of giving us a bit more time against aggro decks for a very low price. It also allows us to push face with weapons while regaining health to survive whatever board we're ignoring.

It also gives us an absurd late game with Kingsbane in that we can continue to remove minions later into the game while still healing.
