After much anticipation, the upcoming Mini-Set for Hearthstone's Fractured in Alterac Valley expansion was announced on Thursday afternoon. Titled "Onyxia's Lair," players will be introduced to 35 new cards (66 in total) when the set launches alongside Patch 22.4 on Feb. 15.

Similar to past Mini-Sets, players can purchase the entire card set outright for $14.99 or 2000 in-game Gold. However, for the first time in the game's history, the entire set can be purchased golden for a price of $69.99.

The breakdown of the 66 card set is as follows: 4 Legendary cards (one of each), 1 Epic card (two in total), 14 Rare cards (two of each), and 16 Common cards (two of each).

In the announcement trailer, Lady Prestor (who is the human form of Onyxia, Deathwing's daughter) serenades an audience of heroes with a jingle about their impending doom. Behind her sinister smile are silhouetting shadows of fire, dragons, and destruction. She's joined by a few gnarly looking whelps who praise their "mama's" destructive ways and further emphasize how the Hearthstone universe "ain't seen nothing yet."

The roughly two-minute video ends with her inevitable transformation into Onyxia who lets out a bellowing roar and scorches the earth.

Players won't have to wait long to see who else Lady Prestor is bringing alongside her when the Mini-Set launches on February 15 as card reveals are scheduled to take place over the course of the next few days.
