Arena Rotation Updated

The Hearthstone Arena has rotated! Here are the current expansions that are playable in the Arena.

New Card Backs

Two new card backs have been added.

  • Shado-pan Card Back
    • Long ago, this card back took up its sacred duty to keep negative emotions from overrunning your board. Though mysterious, it is highly effective.
    • Rewarded for July 2019 Ranked Play
  • Stolen Thunder
    • The hardest part of stealing thunder is getting away with it quietly.
    • Sourced from an upcoming "authorized promotion".
    • The patch notes state this is rewarded for "purchasing the Masters Bundle"


Official Patch Notes

Quote From Blizzard

Today’s Hearthstone update adds a new neutral Legendary Minion, card buffs for every class, new Arena sets, and much more! Read on for details about the Rise of the Mech update.

Introducing SN1P-SN4P!

Make the most of the Rise of the Mech event by logging in anytime between June 3 and July 1 and you’ll earn a golden copy of the new neutral Legendary Mech SN1P-SN4P! Crash this clawed clunker into another Mech to build a behemoth of a bot, then do it again!

Missed the event? Normal SN1P-SN4P can still be crafted for the usual cost of 1600 Arcane Dust.

Important Note: SN1P-SN4P will be considered part of the The Boomsday Project and will rotate with that set, however SN1P-SN4P will NOT drop from The Boomsday Project card packs. Golden SN1P-SN4P will only be obtainable as part of the Rise of the Mech event, and the normal SN1P-SN4P can only be crafted with Arcane Dust.

Card Changes

The terrible tinkerer Blastmaster Boom has been busy in the lab and has cooked up some buffs to cards from every class! For more details on these changes, including developer insights, check out the Rise of the Mech announcement blog here.

Reconnect Improvements:
  • Players who are disconnected from Hearthstone due to an unstable connection, switching applications, or by locking their mobile devices will no longer be directed back to the login/launch screen when attempting to reconnect.
  • The game will now seamlessly reconnect in the background from any screen, instead of only during gameplay. This includes during deck editing, or while browsing the Collection Manager.
    • Note: We are still improving this feature, and you may encounter some issues with the current version.
  • A new popup has been added to alert players of their offline/reconnect status.
Accessing Hearthstone Offline:
  • Players can now access their collection even when their device has lost connection to the Internet.
    • The following features of the Collection Manager can now be accessed while offline:
      • View owned and unowned cards in the collection
      • Create Decks
      • Edit Decks
      • Delete Decks
      • Rename Decks
      • Set Favorite Heroes
      • Set Favorite Cardbacks
      • Opening a pack that was in the process of being opened
    • Any changes made in the collection manager while offline will be saved on the player's device until the next time they regain network access. Note that some changes may be lost if a player creates multiple decks or edits the same deck simultaneously on multiple devices.

Matchmaking Improvements:

  • We've implemented a new feature to reduce chances of matching against the same player and same class multiple times in a row. Some exceptions may occur when players have few matchmaking options near their rank.
  • Match quality should be improved for players in ranks 25 – 21.

Arena Set Rotation

Blastmaster Boom needs more test subjects, and what better place to find them than the Arena? Starting with the Rise of the Mech update, the available cards in Arena drafts will be rotating to the following explosively exciting sets:

  • Classic
  • Basic
  • Goblins vs. Gnomes
  • The Grand Tournament
  • One Night in Karazhan
  • The Boomsday Project
  • Rise of Shadows

Bug Fixes

  • Fixed several issues encountered when making changes to windowed mode, fullscreen mode, and when resizing the game.
  • Fixed a visual issue causing Flare to animate twice when drawing a Cast When Drawn card.
  • Fixed an issue causing the animation times for Kalecgos and Rebuke to play at a different speed from other similar effects.
  • The animation for Togwaggle's Scheme shuffling a high number of cards (5+) has been updated to shuffle in batches of 5 cards and at a higher speed.
  • Hadronox's Deathrattle animation no longer appears larger than intended when it triggers an opponent's Duplicate secret.
  • Fixed an issue that could cause Kabal Chemist to disconnect your opponent when played.
  • Playing Soularium and Plot Twist quickly together will no longer cause a visual issue.
  • Fixed an issue causing the game to freeze if Voidcaller is drawn at the start of your turn while Fel Lord Betrug and Spiritsinger Umbra are on your side of the board.
  • Triggering a secret that was transformed from Shifting Scroll or Chameleos no longer causes the client to lock up for both players.
  • Fixed an issue that could cause streaming data to stop downloading if the game's language was changed during the download process.
  • Fixed issue where the Collection Manager’s filters would not work for newly created accounts.
  • Fixed an issue where heroes would briefly display the banned banner in the collection manager.
  • Fixed an issue which would occasionally leave the screen blurry after finishing a game under certain circumstances.
  • [Monster Hunt] Fixed an issue where Monster Hunt bosses would sometimes incorrectly be displayed as Gobbles during the upcoming boss fight screen.
  • [Dalaran Heist] Bartender Bob should no longer show an empty speech bubble upon exiting a friendly encounter.
  • [Android] Changed how texture packs on Android devices are handled. This may cause some users to have to redownload these assets.
  • [Mobile] Fixed an issue that could cause players to get duplicate season roll popups when relogging on a mobile device.

Dalaran Heist Issue

Quote From Blizzard

Hey everyone,

We wanted to make you all aware of an issue being introduced with today’s (6/3) update that will affect chapters 2-5 of The Dalaran Heist. We are actively working on a fix, and hope to have something out later this week to address the following:

  • Players who are in Chapter 2 – 5 of the Dalaran Heist will be shown the Chapter 1 starting boss in the boss card flip screen instead of the actual boss they are facing.
  • Chapter 2 – 5 will show the crowns for heroes that have beaten chapter 1 instead of the actual progress for chapters 2-5.
    ** This is a visual only issue, progress is still being tracked appropriately.
  • The Hero Power and Deck selection checkmarks will show the chapter 1 versions instead of the correct chapter 2 – 5 versions.
    ** Like the crowns, this is a visual issue only.

Thank you for your patience.
