Hearthstone released Onyxia’s Lair Mini-Set Cinematic Trailer for the new 22.4 patch. According to the new trailer, new cards and more events are coming to Hearthstone. Onyxia’s daughter, Lady Prestor (who appears in the trailer as a human), serenades the viewer before transforming into a dragon and releasing fire. This is just to reveal new cards for the mini-set.

On Feb.15, Hearthstone will release Onyxia’s Lair in the Fractured in Alterac Valley Mini-Set. There are 35 new cards in this Mini-set, which will be revealed a few at a time, but there are 66 in total. The 66 cards will be divided into 4 Legendary Cards, 2 Epic Cards, 28 Rare Cards, and 32 Common Cards.

Players can find these 66 cards in packs of Fractured in Alterac Valley, or you can purchase the entire set for $14.99 or 2000 Gold. Hearthstone will also offer, for the first time, an all-Golden set of all 66 Mini-Set cards for $69.99.

Onyxia, the human/dragon villain of the Lair, seems to be telling the heroes that their pride will be their downfall and that she is bringing something new. This will be something they have never experienced before, alluding to the new cards. While it may seem like a big event, this is mostly just to tell players about the new cards.
