Hearthstone Wiki

Expansions are major card set additions to the game of Hearthstone. Expansions introduce the majority of collectible cards into the game, with each expansion introducing around 130-145 new cards. These cards, referred to as expansion cards, are used primarily to create and build decks to play in Casual or Ranked mode, in either the Standard, Wild, or Twist game format modes. These expansion cards are obtained chiefly through purchasing and opening card packs, through crafting, or through earning Arena rewards.

In early 2017, the developers announced their plans to release three expansions each year, with each expansion featuring around 130 new cards, abandoning their previous annual release cycle of expansion-adventure-expansion.[1] Starting with Knights of the Frozen Throne in August 2017, expansions also featured optional solo-player content in the form of Missions, effectively integrating an adventure into each expansion.[1]

Hearthstone's first expansion was Goblins vs Gnomes, released in December 2014.

Expansion cards[]

Expansion cards are cards added to the game through expansions, or the game's original release, rather than through adventures or other means.

How to get[]

All Standard format expansion cards are obtainable through card packs, through crafting, or as Arena rewards. Standard expansion cards may also be found in the Highest Rank Bonus chest at the end of each Ranked season.

Wild format expansion cards are obtainable through crafting or card packs.

Twist format cards can be obtained depending on whether the current available sets are part of Standard or Wild.

Expansion cards are added to the game in large batches with each new expansion from patch updates. They are different from adventure cards in the way they are obtained. Adventure cards are obtained in small batches, as each wing of the corresponding adventure is released. The introduction of new expansion cards thus tends to have a larger impact on the game's meta than that of adventure cards. The old adventures can still be bought either in-game or in the online Blizzard Shop.

Standard format[]

Main article: Standard format

When the first new expansion is released each year, all card sets that weren't released in the same year or the year prior are removed from Standard format. Cards from these removed sets are termed Wild cards and can only be used in Wild format matches, or Twist format matches, should the current rotation allow it. For details on how the Standard format year works, see The Standard year.

Expansions and adventures[]

Starting in 2014, only a few months after the game's release, Hearthstone presented two different forms of content: adventures and expansions. The former featured a small number of cards and a substantial solo experience, with special bosses and challenges; while expansions brought far larger amounts of cards, but without solo content of any kind. Additionally, while adventures' cards were earned through defeating bosses, expansions' cards were earned through regular means such as crafting and card packs.

Despite these differences, in more general parlance, adventures can be considered equivalent to expansions in other games, with substantial changes to the game's basic play experience that far exceed the impact of a regular patch. For example, Curse of Naxxramas, the game's first adventure, is commonly considered its first 'expansion'.

Between the release of the game in March 2014 and the start of the Year of the Mammoth in spring 2017, Hearthstone saw an alternating pattern of adventures and expansions. However, in early 2017 the developers announced plans to integrate future adventure content into expansions. Starting with the second expansion of 2017, each release will feature optional single-player missions, themed around the expansion and serving to illustrate its story, setting and characters. These missions will be free of charge, but may not award cards in the same way or numbers in which adventures have until now. Further details will be announced later in the year.


  • By the time an expansion is released, Team 5 are "already working a lot on future expansions",[2] including "not only the next [expansion] but the one after that as well".[2] Former Game Director Ben Brode states that the team always have "3-ish expansions in development",[3] although it is likely this also includes adventures. According to Senior Producer Yong Woo, the developers are always "trying to get ahead of the curve".[2] In April 2018, shortly after the release of The Witchwood, Ben Brode stated that the next set had passed through final design, the stage in development during which Team 5 focuses on refining the balance and clarity of the set's new cards. The set after that was currently in the final design process, and the set after was in the initial design phase, during which Team 5 comes up with the ideas for the set's general theme and for the cards and their mechanics. All in all, there are usually at least three sets that Team 5 know about but which players don't yet know about.[4] Later in 2018, the expansion development process was described as a full year cycle with different people working on it for about 16 weeks per team. First, the initial design team spend about 16 weeks nailing down the mechanics, art, and voice overs for the set before passing it onto final design, who refine and tweak the set's mechanics to "make an awesome set that's fair and fun, has cool themes, and all that stuff". At the same time, artists work on creating the card art and golden card animations. When final design starts finishing up, the team records all of the voice lines for the cards while the sound department engineer the various sound effects and the effects artists create the in-game visual effects and animations. At this point, when final design is done and animation is in progress, the engineering team spend time "cleaning up [...] whatever horrible things we've done in design" to ensure that cards function on a technical level and don't cause server or client crashes. The set then heads towards the very end of the cycle, at which point the PR team starts working on how best to market the set and reveal all of the various cards before it is finally released and becomes available to players.[5]


  • Future expansions may bring increased level caps for heroes, although this has not yet been the case.
  • World of Warcraft already has eight expansions, with the latest being Dragonflight. However, only two of the Hearthstone expansions so far have matched with one of these (Wrath of the Lich King, the Burning Crusade), with a preference for original themes that stem off of smaller pieces of Warcraft lore.


The Lich King vs Battle Pets

"Only YOU can decide who will be the victor in this epic conflict."

  • Eric Dodds has jokingly referred to a potential The Lich King vs Battle Pets expansion.
"There was another idea out there... well actually it wasn't really an idea out there, but I was kinda wishing it would have been [...] because it's one that I think would be super awesome, is the idea that maybe we could do something like, you know, "THE LICH KING... VS... BATTLE PETS" [...] of course I've only put that up there to have a little fun with it, but on the other hand as I've been looking at it and thinking about it, it... it's starting to grow on me, actually..."[6]
