Sylvanas is OK in some control decks. I would wait for Iron Juggernaut if you have a lot of the other good control warrior cards. 

THIS meta? Before Naxx it was 70% zoo, 30% ramp druid, that was literally 99% of decks in all mid-range levels where most play is done for most players. 

Every version of the game will have a dominant deck style. I am playing the mad scientist hunter because it is very versatile. I've ran into tons of secret mages though, which can be effective, and bloodlust shamans. I am rank 7 right now, haven't really seen one main deck other than mirror hunter matchups now and then because the popularity of this site and others that post the deck, haha.

This deck works perfectly. You do exactly as it says, make seven 1 attack enemies all he has, and keep playing Keeper of Kings for +6 health each turn. If you have it, use Alexstraza, too, and then while you heal for 6 each turn, you use Leeroy or any 1 other charge enemy to wittle down their health. Works like a charm. Makes the insane battle easy. Well done.

Well, they announced a while ago that there is no reward until you defeat ALL bosses for ALL wings on Heroic. You get the unique card back. That is the only heroic reward.

They discussed having gold cards being the rewards but deemed it too difficult. So while underwhelming, the only reward for Heroic is beating all bosses for all wings.
