I caved and bought Karazhan. To those who may be wondering, Malcheazzar is every bit as op as the card description reads, especially for a control player.
Now I know how you bastards who bought Kel'Thuzad felt.
don't worry Clowns I don't play aggro shaman... I do C'thun control mage... Still need Brann though but that takes a while since I refuse to spend money on the game
