As with most Duels decks, getting the right treasures is key. I got fireshaper first. It came in clutch a few times to get the upper hand in board presence. But the two important ones were Emerald Goggles, and then the two important treasures were Blade of Quel'Delar and Hilt of Quel'Delar. If you get both of these, you silently receive Quel'Delar and always draw it on your first turn. This weapon is 4/4 for 6 mana and deals 4 damage to all enemies after you attack. It's very powerful but isn't always an instant win.
