This is the CosplayGrill Karazhan Tempo Mage Deck he was playing on stream today. AsmodaiTV has been playing a lot of Tempo Mage with subtle card changes. Mage has become a stronger, and much more popular deck since the release of Firelands Portal.
This list has one less Mirror Image in favor of more late game. It’s a slower Tempo Mage list than the standard builds, with Cabalist’s Tome and 2 x Faceless Summoners. You’re going to play Yogg-Saron most games, so start believing in the Yogg!
