Kobolds and Catacombs Secret Mage (Season 45, December 2017)

This secret mage runs a lower curve than the KOTFT secret mage because of the addition of Explosive Runes and Aluneth. These cards allow for an extremely aggressive play style due to Aluneth's ability to give you a hand refill in the late game, while Runes can gain you a tempo advantage on board, or simply close out a game entirely by giving a bit of extra reach.
