Card sets are the major categories into which all collectible cards are divided into. Card sets consist of all expansions and adventures, the two core sets of Basic and Classic, the Hall of Fame set, and the Demon Hunter Initiate set. 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, the other main game format, all card sets can be played.

The following table shows the calendar release schedule for all card sets. The highlighted sets are in Standard format.
- Closed beta began on August 26th 2013 in the Americas region, and September 4th 2013 in the Europe region.
- On January 21st 2014, the game entered its open beta phase.
- March 11th 2014 was the official release date of Hearthstone.
- From December 4-8, Goblins vs Gnomes was heralded with a special launch event which saw all Goblins vs Gnomes cards available in Arena, as well as some uncollectible cards available in constructed play.
- On April 5, 2016, several days before the release of Journey to Un'Goro, Volcanosaur was released into the game during a special launch event for the new Year of the Mammoth.
- On April 4, 2017, near the start of the Year of the Mammoth, all cards in the Reward and Promo sets were moved to the Hall of Fame, effectively closing both sets.
- The Boomsday Project was heralded with a special pre-release event on August 4-5 in which players could open their packs in special Fireside Gatherings and play with their cards in unique Fireside Brawls before the expansion's official release.
- On November 5, 2018, four new cards were added to the Classic set: Tome of Intellect, Pilfer, Call of the Void, and Icicle.
- From November 10 to December 3, 2019, Rastakhan's Rumble was heralded with a special pre-release event in which players could open their packs early and play with them in special Fireside Brawls.
- Starting from April 4, 2019, five days before the release of Rise of Shadows, players who logged in received the free legendary card Archmage Vargoth and were able to play with it in normal games.
- On July 1, 2019, eight new cards were added to the Classic set: Siegebreaker, Gift of the Wild, Righteousness, Brightwing, High Inquisitor Whitemane, Barrens Stablehand, SI:7 Infiltrator, and Arcane Devourer. Furthermore, two new cards were added to the Basic set, Radiance and Plaguebringer, replacing the old cards Mind Blast and Vanish, which were moved to the Hall of Fame in the same update.
- Saviors of Uldum was heralded by a week-long livestreams event in which broadcasters and content creators had early access to the new cards. Fireside Brawl participants also had special early access to the cards.
- On October 8, 2019, in the Doom in the Tomb event, 23 cards from old sets were added as Event cards to Standard play. These cards were temporary copies and not permanent additions to a player's collection. Even if a player already owned some of these cards, they still received copies of the Event cards. When the event ended on December 5, the cards disappeared from a player's collection. In total, there were 4 common, 4 rare, 6 epic, and 9 legendary cards temporarily added for this event.
- On November 5, 2019, Sathrovarr was released into the game, a month prior to the official release of Descent of Dragons. Sathrovarr was most likely introduced into the game as a possible inclusion in Holy Wrath Paladin decks at the time with Shirvallah, the Tiger.

Six new priest cards replaced the ones moved to the Hall of Fame: Psychic Conjurer, Power Infusion, Kul Tiran Chaplain, Scarlet Subjugator, Shadow Word: Ruin, and Natalie Seline.
- On April 2, 2020, the Demon Hunter Prologue was released, and players completing the mission unlocked 10 demon hunter Basic cards and the Demon Hunter Initiate set, which contained 20 demon hunter cards. The 30 cards were locked and unusable in Play mode until April 7th.
- On July 14, 2020, Transfer Student was released into the game, three weeks prior to the official release of Scholomance Academy.
Card sets can also be divided into more specific categories:
- Basic cards are the first cards players get in the game, received through the starting experience and leveling. Basic cards are permanently part of the Standard format.
- Classic cards are the vast majority of the cards that were available to collect at the launch of Hearthstone, forming the initial core of the game together with the Basic cards. They too are indefinitely in Standard format.
- Expansion cards are those 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.
- Adventure cards are those cards added through adventures, for example Curse of Naxxramas, Blackrock Mountain, The League of Explorers and One Night in Karazhan. Similar to expansion cards, they may be in Standard or Wild format based on the calendar year their adventures were released.
- Hall of Fame cards contain all cards formerly in the now-defunct Promo and Reward sets, as well as a few cards from Classic moved for game balance reasons. They are now collected and played as Wild format cards.
- 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.
The sets could alternatively be categorized by the way players obtain their cards:
- Basic cards are uncraftable and are obtained through accumulating experience and leveling classes.
- Classic cards and Standard expansion cards can be found through card packs of the corresponding set, crafting, as Arena rewards, or from Ranked rewards.
- Wild expansion cards are obtained through card packs of the corresponding set, purchased from the Shop.
- Adventure cards are earned by completing the corresponding adventure.
- Hall of Fame cards can only be obtained through crafting.
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.
Basic is a large, freely available card set, with 150 cards, 133 of which are collectible. Many Basic cards are neutral, available to heroes of any class. There are 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 are 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 lack the gem that normally indicates card rarity, leading to a common misconception that all Basic cards are free.
All neutral Basic cards are automatically included in players' collections. Five of the class-specific Basic cards are known by 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 can be obtained by leveling a specific class of hero to a certain level. Raising a hero of the correct class to the required level will '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 consider it important to keep cards from the Basic set relatively simple and their functions easy to understand. 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.
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.
Classic (formerly known as Expert) is the largest card set, with 294 cards, 240 of which are collectible. It features 135 collectible class cards (15 for each class) and 105 collectible neutral cards. Classic cards can 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 feature 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".
Regular and golden Classic cards can be obtained in four ways:
- through opening Classic card packs;
- through crafting;
- as Arena rewards;
- or through the Highest Rank Bonus chest, for Golden cards only.
- Main article: Expansion
Cards from Standard format expansions can be obtained through the same means as Classic cards:
- opening card packs matching the expansion
- through crafting
- as Arena rewards
- golden cards can also be obtained through the Highest Rank Bonus chest
Cards from Wild format expansions were once obtainable the same way, but now can only be obtained through crafting or purchasing card packs. 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.
- Main article: Adventure
Card sets based on adventures are smaller than expansion sets, usually bringing around 30-45 new collectible cards. Five adventures exist in total:
- Curse of Naxxramas
- Blackrock Mountain
- The League of Explorers
- One Night in Karazhan
- Galakrond's Awakening
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.
Hall of Fame
Cards are inducted into the Hall of Fame from the Classic, Reward, and Promo sets. Problematic, frequently-played, and design-hindering cards are 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.
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.
Being Wild format cards, Hall of Fame cards can only be obtained through crafting. When cards are moved to the Hall of Fame set, they will be removed from their previous sets, and will no longer appear in card packs or be offered as rewards in the Arena, Highest Rank Bonus chest, or Heroic Tavern Brawl.
All Hall of Fame cards are pictured below. Full dust refunds were granted on April 6th 2017 for those cards that moved from the Classic set (and not the Reward or Promo set) to the Hall of Fame set, up to the maximum usable number of copies owned, preferring golden copies over regular copies. For details on how the past dust refund worked, please see Hall_of_Fame#Dust_refunds.
|Name / Desc||Rarity||Type||Subtype||Class||Cost||Atk||HP||Description|
Give your minions Stealth until your next turn. Rogues conceal everything but their emotions. You can't get 'em to shut up about feelings.
Freeze a character. If it was already Frozen, deal 4 damage instead. The trick is not to break the lance. Otherwise, you have "Ice Pieces." Ice Pieces aren't as effective.
Destroy a minion. Your opponent draws 2 cards. Another one bites the dust.
Whenever a minion is healed, draw a card. They help the downtrodden and distressed. Also they sell cookies.
Give a friendly minion +4/+4 until end of turn. Then, it dies. Horribly. We cannot even describe how horrible the death is. It's CRAZY bad! Maybe worse than that. Just don't do it.
Double a minion's Health. Double the trouble. Double the fun!
Deal 5 damage to the enemy hero. This spell blasts you directly in the MIND.
|Acolyte of Pain||Common||Minion||General||Any||3||1||3|
Whenever this minion takes damage, draw a card. He trained when he was younger to be an acolyte of joy, but things didn’t work out like he thought they would.
Spell Damage +1
Battlecry: If your deck has only odd-Cost cards, draw a card. She's so odd, you can't even.
Battlecry: Silence a minion. Spellbreakers can rip enchantments from magic-wielders. The process is painless and can be performed on an outpatient basis.
Return all minions to their owner's hand.
Battlecry: If your deck has only even-Cost cards, deal 2 damage. Makes shockingly good unagi.
Battlecry: Each player draws 2 cards. They can see the future. In that future both players draw more cards. Spoooky.
Draw cards until you have as many in hand as your opponent. This is not just a favor, but a divine one, like helping someone move a couch with a fold out bed!
|Mind Control Tech||Rare||Minion||General||Any||3||3||3|
Battlecry: If your opponent has 4 or more minions, take control of one at random. Mind Control technology is getting better, but that's not saying much.
Your cards and powers that restore Health now deal damage instead. The Auchenai know the end is coming, but they're not sure when.
Spell Damage +1. Battlecry: Draw a card. They initially planned to be the Beryl or Cerulean drakes, but those felt a tad too pretentious.
Charge. Battlecry: Discard two random cards. Summoning a doomguard is risky. Someone is going to die.
Deal 5 damage. Restore 5 Health to your hero. Often followed by Holy Smokes!
Battlecry: Draw a Pirate from your deck. Pirates and Parrots go together like Virmen and Carrots.
Secret: When your hero takes fatal damage, prevent it and become Immune this turn. Ice is nice, and will suffice!
Your Hero Power becomes 'Deal 2 damage'. If already in Shadowform: 3 damage. If a bright light shines on a priest in Shadowform… do they cast a shadow?
Battlecry: If your deck has only odd-Cost cards, double the Health of your other minions. Some moths are attracted to flame. This one's attracted to disco.
Battlecry: If your deck has only odd-Cost cards, gain +2/+2. Majestic. Ethereal. Still pretty down in the dumps, though.
Costs (1) less for each other card in your hand. His mother said that he was just big boned.
Costs (1) less for each damage your hero has taken. He gets terrible heartburn. BECAUSE HE IS FULL OF LAVA.
Charge. Has +1 Attack for each other Murloc on the battlefield. He's a legend among murlocs. "Mrghllghghllghg!", they say.
|Elite Tauren Chieftain||Legendary||Minion||General||Any||5||5||5|
Battlecry: Give both players the power to ROCK! (with a Power Chord card) He's looking for a drummer. The current candidates are: Novice Engineer, Sen'jin Shieldmasta', and Ragnaros the Firelord.
Charge. Battlecry: Summon two 1/1 Whelps for your opponent. At least he has Angry Chicken.
Battlecry: Summon an AWESOME invention. He's the leader of the gnomes, and an incredible inventor. He's getting better, too; He turns things into chickens WAY less than he used to.
Start of Game: If your deck has only even-Cost cards, your starting Hero Power costs (1). Ever since Sylvanas killed his son, he's dreamed of getting… even.
Deathrattle: Take control of a random enemy minion. Sylvanas was turned into the Banshee Queen by Arthas, but he probably should have just killed her because it just pissed her off.
Double the damage and healing of your spells and Hero Power. He's been exiled from his home, and all his brothers turned evil, but otherwise he doesn't have a lot to complain about.
|Ragnaros the Firelord||Legendary||Minion||Elemental||Any||8||8||8|
Can't attack. At the end of your turn, deal 8 damage to a random enemy. Ragnaros was summoned by the Dark Iron dwarves, who were eventually enslaved by the Firelord. Summoning Ragnaros often doesn’t work out the way you want it to.
|Baku the Mooneater||Legendary||Minion||Beast||Any||9||7||8|
Start of Game: If your deck has only odd-Cost cards, upgrade your Hero Power. In her defense, it did look like a cookie.
|Showing all 35 cards|
|Name / Desc||Rarity||Type||Subtype||Class||Cost||Atk||HP||Description|
At the end of your turn, give a random minion +1/+1.
At the start of your turn, destroy this minion and draw 3 cards.
At the start of your turn, transform a random minion into a 1/1 Chicken.
At the end of your turn, restore 6 Health to a damaged character.
|Mind Shatter||None||Hero Power||Priest||2|
Deal 3 damage.
|Mind Spike||None||Hero Power||Priest||2|
Deal 2 damage.

Summon three, four, or five 1/1 Murlocs.

- This section contains information exclusive to Wild format.
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 formerly 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 formerly 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.
- This section contains information exclusive to Wild format.
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.
- See also: Patches
- Patch 188.8.131.52222 (2020-03-26): Demon Hunter Initiate set added. Cards able to be collected on April 2, 2020 upon completing the Demon Hunter Prologue. Locked from use in Play mode until the release of Ashes of Outland on April 7th.
- Patch 184.108.40.20636 (2017-04-04) Hall of Fame set added. Reward and Promo sets removed. Collectible cards in Basic set which were "common" rarity changed to "free".
- Patch 220.127.116.1174 (2016-04-24): Cards from the Reward set are no longer uncraftable. [This change was quickly reverted, before finally being reinstated in a hotfix on May 4.]
- Patch 18.104.22.16866 (2015-06-15): Promo cards are now listed when viewing the reward set.
- Patch 22.214.171.12434 (2014-12-04): The Expert card set has been renamed to “Classic”.
- Before the release of Journey to Un'Goro, in Hearthstone's game files, cards in the Basic set were tagged as being either of Free or Common rarity, but they are now all tagged as being of Free rarity.
