I have gone from rank 4 to rank 2 with a similar list. I was running Crystalsmith Kangor and Tirion Fordring, but don't think they make the deck better. The result is this budget version, the epic cards are necessary though.

Against most classes the gameplan is just to pressure the opponent until they're dead.

Against hunter you will need the healing from Bronze Explorer and Lightforged Zealot. The Annoy-o-Module is also very good against them.

The hardest match-up was warrior, they have better tempo and more value.
