Hearthstone Blackrock Mountain - Hidden Laboratory Strategy

I have beaten the final wing of Hearthstone Blackrock Mountain Hidden Laboratory Normal Mode the same night it was released. With that, I have obtained all the Blackrock Mountain and class cards. I walk the talk and I will guide you to get more Legendary cards without purchase.

The final wing Hidden Laboratory bosses were all beaten with one class, namely Priest. The reason, the computer either had 2 silence cards or 2 removal cards in their deck. It is very easy to take advantage of it even when playing against real players. When both cards are used up, you just need to buff one taunt card to very high health and there is no way they can get pass it. So the win condition will be to buff a Deathlord to extreme high health with even free Power Word Shields, Divine Spirit, Dark Cultist (Nax). I was lucky to have 1 Velen's Chosen, 1 Temple Enforcer and 1 Inner Fire with the free decks from those quests of spectating a friend win. Finally, a Kel'Thuzad to repeated revive your Dark Cultist and Temple Enforcer and buff your minions health to seal the victory.

Omnotron Defense System

Hero Powers (Normal) -
Activate Arcanotron! (2 mana)
Activate Toxitron! (4 mana)
Activate Electron! (6 mana)
Activate Magmatron! (8 mana)
Activate! a random tron! (4 mana)

Hero Power (Heroic) -
Activate Arcanotron! (0 mana)
Activate Toxitron! (2 mana)
Activate Electron! (4 mana)
Activate Magmatron! (6 mana)
Activate a random tron! (2 mana)

I chose Priest due to past experiences. First try and I was successful. I put in all my favorite free spells like Holy Smite, Holy Nova as damage would +2 for Arcanotron and cost -2 for Electron. Also removal and buff spells. Their Toxitron will help you to AOE 1 damage but your hero healing power is 2. I saw in gamepedia the boss deck had 2 Earth Shocks and no removals. So if they do not draw Earth Shock and you buff your Deathlord (Nax) to oblivion and Inner Fire, it will be a textbook boss win.

I saw in other sites like gameskinny recommended Warrior as well. I believe it will work as Toxitron will buff your enrage minions or multiply your Grim Patron.

Recommended Class: Priest/Warrior
Recommended Cards: Holy Smite (F), Holy Nova (F) Northshire Cleric (F), Dark Cultist (Nax), Divine Spirit (F), Power Word Shield (F), Shadow Words (F), IBO, High Health Minions, Kel'Thuzard (Nax), Inner Fire, enrage minions, Gurubashi Berserkers

Hearthstone Blackrock Mountain - Blackwing Lair Strategy

I have beaten Hearthstone Blackwing Lair. I will guide you with real-time strategies and personal experiences with clearing them with with most of my basic, Nax and Blackrock wing cards as much as possible. I walk the talk by clearing the wing myself first, then help you get more Legendary cards without purchase.

Razorgore the Untamed

Hero Power (Normal) - The Rookery - Give all Corrupted Eggs +1 Health, then summon one. (1 mana)

Hero Power (Heroic) - The Rookery - Give all Corrupted Eggs +1 Health, then summon one. (0 mana)
I used the basic face rogue deck from Sottle at Icy-Veins with card swaps to defeat Razorgore. You'll need the tempo e.g. Backstab, Shiv, Fan of Knives, Assassinate, Deadly Poison, Sap to clear the Corrupted Eggs before they get bigger and hatch. Combine this with a good mana curve of cheap, effective/Deathrattle minions, weapons and finally expensive efficient minions like Chillwind Yeti, Loatheb, Sludge Belcher and Boulderfist Ogre to defeat Razorgore. RIP Razorgore.

Good luck!

Hearthstone Blackrock Mountain: Blackrock Spire Strategy

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

Hearthstone Blackrock Mountain: Molten Core Strategy

Cleared Hearthstone Blackrock Mountain: Molten Core on my first night with my basic decks plus cards from Curse of Naxxramas. Similar to Hearthstone Blackrock Mountain: Blackrock Depths I cleared on the first night, you must take note of the computer's heroic powers before and when you play them.

Without further ado, let's burn in...

GARR

Garr's Heroic Power is deal 1 damage to all minions (including his own). What's the perfect hero for it? You've guessed it. Warrior enrage deck. The class challenge showed me the way later. I cleared first time with Priest as I do not know what was the Garr's Heroic Power and usually from experience, Priest do well in adventures.

Things to note is his 7 Firesworn minions, each of which deal a certain amount of damage for each one that dies during a turn. That's just 1 damage in Normal mode, but it goes up to a whopping 3 in Heroic. Even if you managed to pick them off individually, that would be 21 damage. On top of that, they stack. If two die at the same time in a single turn, each one does 6 damage. You can see how easily this can get out of hand.

Also Garr uses Druid spells as one of 1st spell to come out was Mark of Wild (+2/+2 Taunt) enabling the 0/5 Firesworn minion to become 2/7 with Taunt and attack. So pack some Silences, IBO or/and Mass Dispels with you. Disrupt each Firesworn health differently so that they die individually and not altogether. Use the 1 damage to your advantage to heal and draw cards with Northshire Cleric. Heck, Nerubian Eggs help too. Power Word Shield, Divine Spirit and Dark Cultists helped me a ton as I managed to bring the health so high that they are unkillable. Remember Grim Patron in the 1st Wing? Here, you can make full use of it to populate the whole board. Good luck!

Recommended Class: Priest/Warrior
Recommended Cards: Silences, Mass Dispel, Northshire Cleric (F), Dark Cultist, Divine Spirit (F), Power Word Shield (F), IBO, Grim Patron, Enraged minions, Rampage, Nerubian Egg
