Hearthpwn

Deck is built around the assumption that you will use the stone on first turn, and then stall out/control the board until you can fish one of the runeblades from the Instructors deck and beat him with it.  One runeblade will give you 40 points of damage, and while victory is possible without the runeblade, it's not as likely.  As there are 4 of them in the deck,. your chances of getting one are greatly increased.

Everything else in the deck is there to either mitigate the runeblade, or help stall. The AI will generally ignore Lightwell, so it's possible to use this to help keep you going.  Lightwell also helps counter the Instructor's hero ability.  Plan to have the runeblade eat one minion, and also hold back Acidic Swamp Ooze and Bloodsail Corsair to deal with it, as the AI will generally attack with it the turn that they play it, and this generally leaves it as a 10/1.

You always want a taunt up, as the runeblade will deal 20 damage to you if the Instructor hits you in the face with it.  While trying to keep control of the board, keep in mind that the instructor has Brawl, but he may not be the smartest about playing it.
