The key is to survive until you have at least Malchezaar Imp, Mechathun and Tome Tampering in your hand. Try to utilize the heal of Aranasi Broodmother as it can be affected by the drawing mechanics of Kobold Librarian.
The hardest matchup should be mill decks, Big Priest, Secret Mage and deck containing disruption like Theotar and Dirty Rat. This deck should dominate aggro decks since it has too many defensive tools, especially Defile.
