With Hearthstone's most recent expansion, The Boomsday Project, a little over a month old, the development team released information pertaining to the health of the game and what players can look forward to in the future. 

In the blog post, Blizzard relayed their perspective on the state of the Standard and Wild meta, cards they will be keeping an eye on for nerfs going forward, an adjustment to the new player experience, the in-client tournament add-on and more. The full post can be found here. 

In addition to the details above, the Hearthstone team announced the addition of four new cards to the same that will be available to craft and open in Classic packs next month. As more and more cards have rotated into the Hall of Fame set, Blizzard felt it was appropriate to replace them to further solidify a class' identity. 

Mage picked up two new cards in Icicle and Tome of Intellect. Icicle naturally fits in the Mage's theme of freezing opposing minions and replaces the slot that was left when Ice Lance rotated out, even though they operate quite differently. Tome of Intellect adds randomness to the class and the ability to add a random Mage spell which synergizes well with existing cards and archetypes that exist.

Warlock picks up Call of the Void to further push their Demon-minion-focused decks while being cheap enough to allow newer players to see what crazy creatures the game has under the Demon tag. It's harmless enough that it likely won't see play in top meta decks but it should help build out the Classic set for Warlock. 

The final card added, Pilfer, fits right into the identity Blizzard has been pushing for a while, theft. A cheap card that allows less-experienced players to experience the wackiness that comes with stealing a powerful card from your opponent's class can create some fun and ever-lasting memories. 

Blizzard's statement regarding the addition of the new cards and the potential for more in the future is as follows: 

"When designing these cards we are thinking about new players’ first experiences playing Hearthstone.  They should be relatively straightforward while still creating some exciting moments. They also give players a chance to see and play with cards that they don't own. At the same time, it’s important that they aren’t so powerful that they limit future design or cause problems (since they’ll be in Standard for longer than 2 years.)

Looking forward, we expect more cards to join the Hall of Fame. There are also still some gaps in Classic where neutral Legendary cards joined the Hall of Fame, so we’re considering adding some new cards to the Classic set in the future."
