Heroic Zinaar Deck
This is the deck that I used to defeat Heroic Zinaar after 2 tries:
The basic idea was to get huge value from a hand filled with "Wishes." I waited until I had two Flamewalkers on the board and the unloaded with 6 Wishes. This cleared the board of his minions and set up a situation where any spell I cast would do 4 additional damage. I finished with 24 health and a board full of minions. It is also important to keep some minions with Taunt on the board, as this protects your other valuable assets.

Used a contemporary Secret Paladin and won on my second try.
