Blizzard launched Hearthstone Update 29.0 and its accompanying patch notes early this week. The headliner is the Whizbang’s Workshop expansion, which brings 145 new cards into rotation on March 19.  You’ll also have access to the new “Miniaturize” keyword. Any card with that keyword that gets played will add a 1-mana, 1/1 version of the card to your hand. There were also a massive array of card balances and other features implemented in this patch, so be sure to check out the full notes below:


Whizbang’s Workshop Opens on March 19!

Hearthstone Card Updates

New Cards 

Warcraft Rumble can’t wait to join us for the birthday festivities! Four new Warcraft Rumble themed cards will be added directly into the free Core Set today, with Patch 29.0!  

Card Adjustments 

Several balance changes throughout the years were made because cards were too powerful for Standard, even if not necessarily too powerful in Wild. On March 11, with Patch 29.0, the following cards will be adjusted. Most of these changes are to cards currently in Standard, in anticipation of their rotation into Wild on March 19. The following cards will be reverted to their original form: 

The following cards will be updated or reverted as follows: Death Blossom Whomper  

Halduron Brightwing 

Switcheroo 

Tome Tampering 

Mechwarper (Mech) 

Balance changes to Core Set cards will also take place on March 11. See the Core Set blog for details.

The Year of the Pegasus Takes Off 

When Whizbang’s Workshop goes live on March 19, so will the start of the next Hearthstone year: the Year of the Pegasus. At that time, cards from the Year of the Hydra (Voyage to the Sunken City, Murder at Castle Nathria, March of the Lich King, and Path of Arthas) rotate out of Standard. The Core Set rotation—cards leaving and entering Core—will also happen on March 19. 

Battlegrounds Updates

Arena Updates 

On March 11, all ongoing Arena runs will end and a new Arena season will begin. Celebrate 10 years of Hearthstone with this special Arena Season that includes cards across all Hearthstone expansions! Instead of a group of sets that apply to all classes, each class has its own curated list of cards that can include cards from any expansion. The first pick of each Arena draft will be a Legendary card, which will be the only Legendary card offered in your draft. Duels Treasures have been removed from Arena drafts. 

Signature Frame Update 

We’ve made a new frame for Signature cards in Whizbang’s Workshop! The rarity gems on these Signature cards are also differently shaped for different rarities, making them more accessible and easier to read. This new frame pulls from general Hearthstone aesthetics, but is flexible enough to work with a variety of Signature card themes. All current Signature cards will remain unchanged, but all future Signature cards will use this new frame. The art style within each frame will update to match the feel and themes of each expansion. 

Whizbang’s Workshop Catch-Up Packs 

Catch-Up Packs are back for Whizbang’s Workshop! Just like Showdown in the Badlands Catch-Up Packs, Whizbang’s Workshop Catch-Up Packs include 5-50 cards from previous Standard sets, depending on your collection completion levels for those sets. However, because of the Standard rotation, there are only three eligible sets for Whizbang’s Workshop Catch-Up Packs: Festival of Legends, TITANS, and Showdown in the Badlands. Since these packs pull from three sets instead of five, the details have shifted to meet the overall goal of still giving 5-50 total cards per pack. You can read all the specifics on the updated Disclosure Page.This new breakdown only applies to 3-set Catch-Up Packs (currently only Whizbang’s Workshop). 5-set Catch-Up Packs (currently only Showdown in the Badlands) will still work as they did before. Each type of Catch-Up Pack is distinct and pulls from an established pool of cards, meaning that Badlands Catch-Up Packs are not updating to Whizbang’s Workshop Catch-Up Packs or changing in any way with rotation. 10-Year Anniversary Card Back Celebrate 10 years in style! Log in today and complete a special Legendary Quest to earn the 10-Year Anniversary Card Back.
