Is Pirate Rogue as efficient as Pirate Warrior? Probably not! But it's still one heck of a list that should get you pretty far on the ranked ladder. It has all sorts of tools for various situations, and all this is spiced up by a healthy number of pirates.
Try to equip Assassin's Blade as early as possible and buff it up using Cutthroat Buccaneer and Deadly Posion. Then, play Bloodsail Raider, Dread Corsair, and Phantom Freebooter. All of them will synergize perfectly with your 6/4 weapon, which alone can deal 24 points of damage.
Ticket Scalper and Cursed Castaway will provide you with card draw, so you will never be out of threats.
