I'm a f2p casual player since season 1. Usually finish season about rank 3-4 because i don't have enough time to grind for legend. First time hit legend this season mainly because of this deck. I don't keep score but i'm sure winrate is really high. I recommend this deck to everyone trying to go for legend. You can substitute some cards as a personal preference but this list gave me best results. You can steal so many games with early Edwin VanCleef and Questing Adventurer and 1xArcane Giant just seems perfect for me and its usually gonna be less than 5 mana. 2xSwashburglar and 1xSouthsea Deckhand are my pirates to go with. I feel like 3 is just enough to trigger Patches the Pirate consistently and Southsea Deckhand doesn't perform much better then Swashburglar on turn one since you're almost always trading with 1/1s. Pirate warrior and midrange hunter are usually good matchups if you can get a big vancleef or questing early on. Taunt warrior is a bad matchup and i suggest you go all in as soon as possible. Quest rogue is 50/50 more dependent on his good or bad draws too be honest, you should just try to put as much pressure as you can and clear his board wisely till you recognize its time to go all face just watch out for Vanish. Elemental shaman and midrange paladin are kinda bad matchups but they are not as popular as other decks.
I hope you will enjoy playing this deck, and hit legend like i did. Good luck everyone and have fun :)
