'Hearthstone' players everywhere are waiting for the recently announced Blackrock Mountain Adventure mode to finally release; bringing in new cards, a new board, new strategies, and a whole lot more. In light of that, on March 26, Blizzard let their loyal gamers in on some details about a new BRM wing - Hidden Lab.

Check out the original Blizzard post here that showcases some of the new cards featured in the upcoming BRM expansion.

Below is a general breakdown of the three new cards revealed for the upcoming Blackrock Mountain Adventure mode:

Volcanic Drake, 6 mana 6/4 common neutral dragon

Costs (1) less for each minion that died this turn.

Drakonid Crusher, 6 mana 6/6 common neutral dragon

Battlecry: If your opponent has 15 or less health, gain +3/+3.

Nefarian, 9 mana 8/8 legendary neutral dragon

Battlecry: Add 2 random spells to your hand (from your opponent's class).

Out of the three new cards revealed today, Nefarian is the only Legendary one that comes with the standard dragon coiled border. Evidently, marking this card as Legendary makes sense considering he was one of the more revered final raid bosses in Blizzard's 'World of Warcraft' MMO.

On that note, it seems that the BRM expansion is going to bring about the same type of content additions as the previous adventure mode expansions, a slew of new cards, a new game board, new single player bosses to defeat and reap the rewards from, and a mess of new deck strategies.

While there is no release date for the upcoming BRM expansion, rumor has it that it's going to be available relatively soon, considering it's available for pre-order now. Players who choose to pre-order the upcoming Adventure will obtain the Molten Core card back.
