I used my own Hearthstone Blackrock Mountain: Blackrock Spire strategy to clear on my first night again with my basic decks plus cards from Curse of Naxxramas. Similar to Hearthstone Blackrock Mountain: Molten Core I cleared on the first night, you must take note of the computer's heroic powers before and when you play them.
This wing I felt was even easier for Normal Mode as not much surprises like the previous final stage of Molten Core. My general feeling is Blizzard wants to give you the cards.
The strategies and personal experience covers the normal mode. Without further ado, let's see how my strategy tran-Spired (pun not intended)...
Highlord Omokk
Normal: 1 Mana - Me smash: Destroy a random damaged enemy minion
Heroic: 0 Mana - (Automatic): Destroy a random enemy minion
As usual, I did not know their heroic powers and ventured with Priest. Well, you've guessed it. I was slaughtered as my minion just have to be damaged to be killed. Divine Shield will help you in Normal mode but not in Heroic mode. I believed I cleared it either with Paladin or Warlock. Anyway, if you were using Paladin pack yourself with Divine Shields and minions with that, Avenge (you should have that from Nax), Champion swords etc. to get board control and also no damage.
For Warlock, I used deathrattle cards so that all units had to be killed twice even with their heroic powers and also for the card draw. Use low cost minions as they will die if damaged anyway. It should not be too hard for normal mode.
Recommended Class: Paladin/Warlock
Recommended Cards: Divine Shields (F), Shielded Minions, Avenge, Champion Sword (F), Deathrattle cards
