Hearthstone Cataclysm expansion launches on March 18

At the recent Hearthstone Spotlight, Blizzard unveiled Cataclysm, the game’s next expansion featuring two new keywords and an array of new cards.

In this new expansion, Murozond shattered the Hourglass of time and brought forth a major threat to this timeline. While Deathwing by himself is a fearsome foe, what makes this scenario even more dangerous is the fact that this version of Deathwing is one who succeeded in his timeline’s Cataclysm.

Hearthstone’s own Cataclysm was revealed with a new cinematic trailer, which you can watch here:

As with other expansions, this one features the return of the Colossal mechanic, and this time, they are more fearsome thanks to their new Keyword: Herald.

How it works is that playing a minion with Herald summons a Soldier that carries the same effect as your Colossal’s appendages. Using a Herald twice doubles the power of your Colossal, appendages, and soldiers. Plus, Herald even empowers Deathwing.

Next, there’s the new Shatter keyword. When you draw a card with Shatter, it breaks apart, and its pieces fly to opposite ends of your hand. By making these pieces touch again (through playing the cards between them), they recombine and grant two effects instead of just one.

Along with these, the expansion also features a series of in-game events, as well as an array of rewards for participants. As a bonus, all cards from Into the Emerald Dream and The Lost City of Un’Goro (including Goldens) will be free to play for everyone starting March 11.
