Card set

Card sets are the major categories into which all collectible cards are divided into. Card sets reflect how collectible cards can be obtained, and they also determine whether collectible cards can be used in Standard format.

In Standard format, only the card sets from the first two Standard years are allowed for building decks. A card set rotation occurs every year at the beginning of April in which the card sets from the oldest Standard year are removed from Standard play. In Wild format, however, all card sets can be played. In Twist format, any card set may be able to be used, provided that it's part of the available sets in the current rotation.

List[]

As of Patch 27.2.2.184727, there are 35 card sets, 7 in Standard format and 28 in Wild format.

Mini-set cards are included in the "Collectible" section for each expansion.
LEGACY and EXPERT1 are the in-game names of two separate sets that are merged into one set, called "Legacy", in the Collection manager. EXPERT1 used to be the Classic set prior to March 30, 2021.

Categories[]

The main distinction between card sets is whether its cards are usable in Standard format or in Wild format.

Card sets can also be divided into more specific categories:

Core cards are the first cards players get in the game, received through the starting experience and leveling. Core cards are permanently part of the Standard format.
Legacy is a special set that was added when the Core set was introduced. It contains cards from every removed set: Promo and Reward sets, as well as all Classic, Basic and Hall of Fame cards.
Expansion cards are cards added through expansions - for example Goblins vs Gnomes, The Grand Tournament and Whispers of the Old Gods. Expansion cards released in the last two calendar years are part of Standard, while earlier cards are in Wild.
- Mini-set cards are cards that are considered to be part of an existing expansion and can be obtained through that expansion's card packs, but were added later and have a different watermark. Mini-sets are not considered separated card sets.
Adventure cards are cards added through adventures, for example Curse of Naxxramas. Similar to expansion cards, they may be in Standard or Wild format based on the calendar year their adventures were released.
There are also two special sets that are unique in structure and availability:
- Demon Hunter Initiate cards are a handful of cards added to the Year of the Dragon to support the new Demon Hunter class added in the Year of the Phoenix.
- Path of Arthas cards are a handful of cards added to the Year of the Hydra to support the new Death Knight class at the time of its release.

The sets could alternatively be categorized by the way players obtain their cards.

Standard expansion cards can be found through card packs of the corresponding set, crafting, as Arena or Duels rewards, or from Ranked rewards.
Wild expansion cards are obtained through card packs of the corresponding set or through Wild packs, purchased from the Shop.
The availability of Twist expansion cards depends on their format.
Craftable Legacy cards can also be opened from Wild packs.
Free cards are uncraftable, but can be obtained after completing New player's ranked system.
Adventure cards are earned by completing the corresponding adventure, or crafting once that adventure rotates to Wild.

For the purposes of the wiki, further categories can be realized for uncollectible cards:

Boss cards are used to categorize cards used by bosses. While not collectible by players, they are encountered during play in Adventures and Tavern Brawls.
Tavern Brawl cards are used to categorize cards used exclusively in Tavern Brawl decks. These are not collectible and are not featured outside of Tavern Brawl.
Battlegrounds and Duels cards are used to categorize cards used exclusively in Battlegrounds and Duels.

Core[]

Main article: Core

Core is the primary card set of Hearthstone. It was first made available on March 25th, 2021, shortly before Forged in the Barrens launched. It is the largest set in Standard format, usually featuring over 200 cards at any time.

The purpose of the Core is to provide a modern collection of starting cards to players of all types and make Hearthstone even more approachable for newcomers. Some of the Core cards return from previous sets, some are reimagined favorites, some are completely new. Regardless, all Core cards can be obtained for free through leveling up classes, while their golden cards can be obtained by winning in Ranked, Arena, or Duels games.

Unlike Basic and Classic, which were the main card sets of Hearthstone, Core is refreshed each year. At the end of every year, a new Core Set will take the place of the previous, composed of new and existing cards. When that happens, Core cards that are rotating will be swapped with new ones in the player's Collection automatically. The original versions of these cards can still be crafted and disenchanted, but the player will be unable to keep their Core versions.^[10]^[11]

Core cards can be used in Standard and Wild format, as well as Twist format provided the set is in the current available card sets, although you may still only have the normal number of copies of any given card in your deck (two for most rarities, one for legendaries).

Legacy[]

Legacy is a special Wild format card set implemented on March 25th, 2021. It is the largest set in the game, containing 412 cards. Legacy is made of cards from the former Basic, Classic, and Hall of Fame sets.

In the game data, Legacy is technically a representation name of two separate sets, coded as LEGACY and EXPERT1.

The true Legacy set contains these following cards:

All former Basic cards
All former Reward cards (Captain's Parrot and Old Murk-Eye)
All Promo cards (Elite Tauren Chieftain and Gelbin Mekkatorque)
All replacement cards for former Classic cards that were Hall of Famed, such as Icicle.
All new cards introduced in the Core set that did not return for the next Core set, such as Crimson Clergy.

Expert1 is a set that contains all cards that were in the Classic set in 2014 at the time of its release, including Classic cards that were put in the Hall of Fame throughout the game's lifespan. Gameplay-wise, Expert1 is represented as Legacy, having the same name as the true Legacy set.

Expansions[]

Main article: Expansion

Card sets based on expansions are the largest sets after Core, usually bringing around 130-180 new collectible cards (when combining with their mini-sets).

Cards from Standard format expansions can be obtained through:

opening card packs matching the expansion
through crafting
as Arena or Duels rewards
golden cards can also be obtained through the Highest Rank Bonus chest
participating in Rewards Track or Event Tracks

Cards from Wild format expansions were once obtainable the same way, but now can only be obtained through crafting or purchasing card packs.^[12] Neither individual cards nor card packs are offered as rewards in the Arena, nor do they feature in the Highest Rank Bonus chest. However card packs for Wild format expansions are available in the shop and any card packs already obtained can still be opened as usual. (See also Wild format#Availability.)

For information on specific expansion sets, see expansion pages, e.g., Whispers of the Old Gods.

Adventures[]

Main article: Adventure

Card sets based on adventures are smaller than expansion sets, usually bringing around 30-45 new collectible cards.

Cards from Standard format adventures can only be obtained through defeating their corresponding adventure wing, which will grant regular copies of the card. Once the player has obtained the regular version, they can then be able to craft and disenchant both the regular and golden versions of that card.

Cards from Wild format adventures can still be obtained through defeating adventure wings, but can now be crafted and disenchanted regardless of whether the corresponding adventure wing was defeated or not.

Mini-sets[]

Main article: Mini-set

Mini-sets are supplemental sets of around 35-38 cards, which continue the theme and mechanics of the previous expansion or year.

Mini-set cards can be obtained from their parent expansion's card packs, or through a bundle which includes all cards from the set. For the purpose of Achievements and progression, mini-set cards are considered part of their parent expansion, although they feature a slightly different watermark behind the card text to differentiate them.

As of Patch 27.2.2.184727, there are currently 8 mini-sets in Hearthstone.

Removed sets[]

Reward[]

Reward cards were moved to the Hall of Fame set on April 4, 2017 with the start of the Year of the Mammoth, effectively closing the Reward set. Reward cards were formerly two cards, Old Murk-Eye and Captain's Parrot, both of which were originally earned through completing certain unique quests.

Old Murk-Eye was rewarded for free upon collecting at least one of every Murloc in the Basic and Classic sets. Golden Old Murk-Eye was rewarded for free upon collecting at least one of every golden version of those cards.
Captain's Parrot was rewarded for free upon collecting at least one of every Pirate in the Basic and Classic sets. Golden Captain's Parrot was rewarded for free upon collecting at least one of every golden version of those cards.

The associated quests were initially removed in Patch 5.0.0.12574, but were reinstated as achievements in Patch 19.0.0.65614 when achievements were officially added to the game. They are also obtained through regular crafting, like most Wild format cards. For a list of associated removed quests, see Quest#Removed.

Promo[]

Promo or Promotion cards were moved to the Hall of Fame set on April 4, 2017 with the start of the Year of the Mammoth, effectively closing the Promo set. Promo cards were special cards awarded as part of specific Blizzard promotions. The Promo set featured 11 cards, only 2 of which were collectible, namely Gelbin Mekkatorque and Elite Tauren Chieftain.

Golden Promo cards were formerly available to be obtained as part of their corresponding promotions; it is no longer possible to obtain these golden cards. Following their promotion periods, regular versions of these cards were uncraftable, but were later made available for crafting. Golden Promo cards cannot be disenchanted, but regular versions can. For the removed promotional quests that offered golden Promo cards, see Quest#No longer attainable.

Golden Gelbin Mekkatorque was offered as a reward for beta testers who helped test the in-game store by making a real-money transaction during the game's beta test.
Golden Elite Tauren Chieftain was available exclusively as a reward for purchasing a ticket to Blizzcon 2013.

Promo cards were created with a design in mind that they offered no substantial advantage to the owner, since the cards were exclusive and of limited availability. Rather, the cards were designed to bring more of an entertainment and RNG aspect into the game. This prevented Promo cards from becoming "must-have" cards for higher-level play.

Promo cards were notable for being the only card set not available in Arena picks.^[13]^[14]

Basic[]

Main article: Basic

Basic was a large, freely available card set, with 150 cards, 133 of which were collectible. Many Basic cards were neutral, available to heroes of any class. There were also 10 Basic cards exclusive to each class. The Coin is also considered part of the Basic set. Because of the nature of the game system, Hero Powers and even heroes themselves are also categorized as Basic cards, but are not counted in this total.

All Basic cards were of free rarity, except for a few uncollectible cards that are common or have no rarity. All free cards are in the Basic set. "Basic cards" and "free cards" are therefore almost, but not exactly, synonymous. All Basic cards lacked the gem that normally indicates card rarity.

All neutral Basic cards were automatically included in players' collections. Five of the class-specific Basic cards were given to heroes as soon as they are unlocked; the other five are gained by advancing those classes in level. A new Basic card is granted for every two levels reached, up to level 10 in each class. All Basic cards are granted in pairs, enabling players to immediately include two of them in their deck if they so desire. Basic cards are uncraftable and therefore cannot be crafted or disenchanted.

A golden version of each Basic card could be obtained by leveling a specific class of hero to a certain level. Raising a hero of the correct class to the required level would 'unlock' the card, granting the player one copy of the golden version of that card. (The second golden copy of the same card is unlocked at a later level). Like the plain versions, golden versions cannot be crafted or disenchanted. While all class-specific golden Basic cards require a hero of the corresponding class to unlock, the required class for neutral cards varies.

The developers considered it important to keep cards from the Basic set relatively simple and their functions easy to understand.^[15]^[16] This allows newer players to get to grips with the game's mechanics before being forced to grasp the subtleties of cards in the other sets. In at least one case this has caused the developers to significantly change the function of a card in development, due to new players finding the function's subtleties too confusing.^[17]

The common rarity originally applied to approximately half of collectible Basic cards, identifying class cards that had to be unlocked by leveling up, and neutral cards that were not available until after the tutorial (with one exception, Goldshire Footman). However, the Year of the Mammoth changed these to be uniformly free. Among uncollectible Basic cards, common rarity still indicates tokens created by other cards, free rarity is used on cards created by Hero Powers, and The Coin and Excess Mana have no rarity at all.

In the Year of the Gryphon, the Basic set was removed from the game, and its cards were moved to the Wild-restricted Legacy set.

Classic[]

Main article: Classic (2014-2021)

Classic (formerly known as Expert) was the largest card set, with 294 cards, 240 of which were collectible. It featured 135 collectible class cards (15 for each class) and 105 collectible neutral cards. Classic cards could be recognized by the distinctive "Hearthstone swirl" behind the card text, not found on other cards.

As the larger and more advanced of the two "permanent" sets included in Standard format, Classic cards frequently featured as core cards in successful decks, and the developers constantly monitor the set's power to ensure it does not form too large a proportion of decklists, thus causing the meta to become excessively stale. As of early 2017 the Classic set is "the most powerful set by a wide margin".^[18]

Classic cards could be common, rare, epic or legendary.

In the Year of the Gryphon, the Classic set was renamed to Legacy. Most of its cards were moved to the Wild-restricted Legacy/Expert1 set.

Hall of Fame[]

Main article: Hall of Fame

Hall of Fame was a special Wild format card set, created on April 4, 2017 just before the start of the Year of the Mammoth. The set contained several collectible cards.

Cards were inducted into the Hall of Fame from the Classic, Reward, and Promo sets. Problematic, frequently-played, and design-hindering cards were moved to the Hall of Fame to remove them from Standard format. Cards were also moved to the Hall of Fame to eliminate the Reward and Promo sets. The developers state that, in the future, they will more likely move problematic Classic cards to the Hall of Fame, whereas problematic cards from other sets will be nerfed instead.^[19]

According to Yong Woo, if a metagame largely consists of decks with too similar cores and ideas, the development team will consider making changes to problematic cards found in such decks. Moving problematic cards into the Hall of Fame is one way in which a fresh meta can be ensured; however, it is not something that the designers plan to do on a regular basis.^[20]

Being Wild format cards, Hall of Fame cards could only be obtained through crafting.^[21] When cards were moved to the Hall of Fame set, they would be removed from their previous sets, and would no longer appear in card packs or be offered as rewards in the Arena, Highest Rank Bonus chest, or Heroic Brawliseum.^[22]

In the Year of the Gryphon, the Hall of Fame set was removed from the game, and its cards were moved to the Wild-restricted Legacy set or returned to their home set in the case of the cards from The Witchwood.

Wild Event[]

Main article: Wild Event

Wild Event was a promotional card set that existed from October 8th, 2019 until December 5th, 2019. It consisted of 23 collectible cards, 5 neutral and two for each class. Wild Event cards were extra copies of notable Wild format cards given to each player for free, and were usable in Standard format. These cards could not be crafted or disenchanted, and had no Golden versions.

All Wild Event cards were removed from the game at the end of the event.
