I beat Maexxna using a version of this.
Heroic Maexxna Guide(Naxxrammus) - Hearthstone Decks
Basically have to mulligan for explosive trap and novice engineer, using engineer as the draw engine for early rounds. Clear spiders initially with explosive trap then drop a pyromancer and clear the rest. After that she's easy. It says a lot about the AI then when you basically have the cheese the game in order to beat them. All they (the bosses) are using are OP powers and numerous copies of the same card with zero strategy.
