The collection manager, also known as the collection, is where a player can go to view their collection of cards, construct and modify custom decks, and craft and disenchant cards. It is accessed from the main menu screen by clicking on the My Collection button, found at the bottom-centre of the screen.
Cards[edit | edit source]
Players can use the collection manager to view all cards in their collection. Individual cards can be inspected in more detail by right-clicking them, showing their flavor text, card set, artist and other information. Cards can be filtered by set and game format, through the button in the bottom-left corner; by mana cost, through the numbered icons along the bottom of the screen; and by class, through the tabs at the top of the screen. A search field at the bottom-centre allows for more detailed filtering based on various properties. At the bottom-right of the screen the player's supply of Arcane Dust is displayed. The 'Back' button returns the player to the previous screen.
By default the collection is set to show only cards usable in Standard format, as set by the filter in the bottom-left corner. If the player sets the filter to "All Cards" or a set which is part of Wild format, or edits a deck that is currently set to Wild format, the collection will switch to Wild format mode, with various changes in the interface to remind the player of the selected format.
Newly acquired cards which have not yet been viewed and moused over, are highlighted in blue, and are indicated in each class tab with a number.
Organization[edit | edit source]
In the Collection Manager, cards are separated into up to ten different tabs, one for each class, and one for neutral cards. Tri-class cards are found in the neutral section. A tri-class card will only appear in the collection if viewed without editing a deck, or editing a deck that can use said tri-class card. The tabs of the ten classes are organized alphabetically in English, with the neutral tab being last. In other languages, the order of the tabs stay the same. When no cards from a tab are valid for the current query, the tab will not appear, but the order of the other tabs will stay the same.
The cards in each tab are then organized by mana-cost. Cards without a mana-cost will be treated as 0-mana. The golden version of a card will appear immediately after the non-golden version of the card. Cards with the same mana-cost are then organized alphabetically in the language of the game client if the game client uses an alphabetical language. If the game client does not use an alphabetical language, cards will be organized by their Unicode values.
Search[edit | edit source]
A text search field at the bottom of the collection manager screen allows players to filter their collection, in further conjunction with the collection's "game format", "card set", "class", and "mana cost" filter interfaces.
The text search function searches for cards that feature the exact text string entered, with an additional feature of utilizing keywords (see below) for the query.
The text search function searches not only through card titles, but also through card texts, classes, types, subtypes, rarities, and card set titles. Any card which includes the exact search text in any of these locations will be listed in the search results. For example searching for "weapon" will return all weapon cards, as well as all cards which include "weapon" in their title or text. Also of interesting note, a search string will also match a run-on phrase that stitches together the card title and card text. For example, searching for "the chained bat" will bring up Raza the Chained, and searching for "hunter spell" will bring up Squallhunter.
This means the text search function searches for text within the following tag locations:
- Card title (whole or partial)
- Card class (mage, druid, Jade Lotus, etc)
- Card type (minion, spell, weapon, hero)
- Card subtype (Beast, Murloc, Pirate, etc)
- Card rarity (free, common, rare, epic, legendary)
- Card set (Naxxramas, Mean Streets of Gadgetzan, etc)
- Card text (whole or partial, including abilities such as Taunt or Charge)
While the search checks each of these search locations, the entire search text must be an exact quote within that location for the card to be returned. Also, the exact quote does not have to consist of whole words. However, when searching for text in locations different from card title or card text, the search text must be a whole word. For example, searching for "beas" will not return all Beast minions. Furthermore, all searches are non-case-sensitive.
- Searching for "rare" or "chicken" will bring up Angry Chicken, but searching for "rare chicken" will return nothing.
- Searching for "mech" or "thermaplugg" will bring up Mekgineer Thermaplugg, but "mech thermaplugg" will return nothing.
- Searching for "freeze character" will not return any results, but "freeze any character" or "freeze a character" will return Snowchugger and Ice Lance, respectively.
- Searching for "k k" or "k knight" will return The Black Knight and Clockwork Knight, even though the search query did not entirely contain whole words.
- Searching for "gnomes" will return all cards from the Goblins vs Gnomes set, but searching for "gnome" or "nome" will only return cards with the word / letter-sequence "gnome" or "nome" in their titles or card texts.
- Searching for the word "the" will result in all cards from The Grand Tournament, The League of Explorers, and Whispers of the Old Gods (since these card set names contain the word "the" in them), in addition to all cards which have the word "the" in their titles or card texts.
Any syntax corresponding to keywords (see below) will be utilized as additional queries to the search and will be quietly omitted from being used in the basic text comparison search as described above.
- Searching for "golden" will not return Elise Starseeker since it is a keyword for golden cards, even though the word "golden" appears in her card text, but a golden copy of Elise will correctly be returned if the player owns one.
- Searching for "mekgineer attack:9 health:7 thermaplugg" will successfully return Mekgineer Thermaplugg.
- Searching for "deck attack:5 has no duplicates" will bring up Elise the Enlightened, Inkmaster Solia and Raza the Chained if they are owned, or if in Crafting mode.
- Searching for "tree missing of life" will bring up Tree of Life, if the card is missing from the collection.
- Searching for "extra arm" will bring up Extra Arms only if there are extra copies of it, as well as cards which you have extra copies of and have "arm" somewhere in their card title or text, such as Armorsmith or Shield Slam.
Once search text is entered, reselecting the search field will cause the previous search text to become highlighted, causing further typing to overwrite it entirely. However, it is possible to edit previous search text through certain workarounds:
- Use an arrow key to get in 'edit-mode' (NB: This does not work on all platforms, such as Mac)
- Copy the text and then immediately paste it back in, allowing you to then modify it at will
- Right-click the text
Keywords[edit | edit source]
In addition to providing basic text searches, the search function incorporates the use of various special keywords.
Keywords are distinct from regular search text in that they apply special rules to the search, limiting results to cards matching their specific requirements. For example, 'golden' will return all golden cards in the player's collection, but will not return regular Elise Starseeker, whose card text includes the word 'golden' (although it will return a golden Elise Starseeker, if collected). This is because 'golden' is a keyword, and overrides the default behaviour of the search function.
- You can combine multiple keywords and regular text for focused searches.
- For example "attack:3-5 mana:2-4 deathrattle" will list any cards that have between 3 and 5 Attack, cost between 2 and 4 mana, and have the word "deathrattle" somewhere in their text or title.
- If two search requirements contradict each other, the search will fail. This includes external filters.
- For example "mana:2 mana:3" will return no cards, as will "mana:2" if entered while the visual mana cost filter is set to 1. However, the same search requirement can be stated multiple times without causing any problems.
The following keywords relate to the player's collection.
|New||new||Lists only newly acquired cards (those not yet moused over).|
|Golden||golden||Lists only golden cards.|
|Extra||extra||Lists cards that you have more than two copies of, and legendaries you have more than one copy of.
|Missing||missing||Lists only cards that you have fewer than two copies of, and legendaries that you have no copies of.
The following keywords can be combined with numerical or text values to limit results. Numerical values can be passed as single numbers or ranges.
- For example, "attack:1" will show only cards with 1 Attack. "mana:4-" will show only cards with a mana cost of 4 or less, and "health:7-9" will only find minions that have between 7 and 9 Health. "owned:3" will only show cards that you own precisely 3 copies of.
- "artist" allows you to search within the name of the artists responsible for creating the art for each card. For example "artist:blizz" will not return Blizzard but will return Mana Wyrm and Lightwell, whose credited artists are "Blizzard Cinematics" and "Blizzard Entertainment".
Keywords which require following values will only be considered keywords if a following value is provided. For example, "attack" will return a number of cards including Ice Barrier and Abusive Sergeant, while "owned" will not return any cards, no matter the size of your collection.
|Attack||attack:<value>, attack:<value>-, attack:<value>+, attack:<value1>-<value2>|
|Health||health:<value>, health:<value>-, health:<value>+, health:<value1>-<value2>|
|Mana||mana:<value>, mana:<value>-, mana:<value>+, mana:<value1>-<value2>, mana:even, mana:odd|
|Rarity||rarity:<value> [free, common, rare, epic, legendary]|
|Type||type:<value> [minion, spell, weapon, hero]|
|Owned||owned:<value>, owned:<value>-, owned:<value>+, owned:<value1>-<value2>|
|Has||has:<value> (same as default text searching)|
Various shorthand keywords exist for certain card sets. As noted previously, any whole words from the title of a card set will non-exclusively return all cards from that set, as well as any other matching cards. However, since this fits the rules for standard searching, only specific keywords are listed below.
As previously mentioned, these keywords return all cards from the specified set, but they also return cards from other sets that match the string.
- For example, if you search for "rr" you'll see all Rastakhan's Rumble cards, but you'll also see the basic card Mirror Image.
|Goblins vs Gnomes||gvg|
|The Grand Tournament||tgt|
|The League of Explorers||loe|
|Whispers of the Old Gods||tog, wog, wotog|
|Mean Streets of Gadgetzan||msg, msog|
|Journey to Un'Goro|
|Knights of the Frozen Throne|
|Kobolds & Catacombs||kc, kac, knc|
|The Boomsday Project||bp|
|Rise of Shadows||ros|
|Saviors of Uldum||sou|
|Descent of Dragons||dd, dod|
|Ashes of Outland||ao, aoo|
Decks[edit | edit source]
- Main article: Deck
Each deck is composed of 30 cards, and is tied to a specific class. For basic information and deck building restrictions, see Deck. Each deck occupies a 'deck slot', with the number of deck slots limiting how many decks the player can possess in the in-game client. There are 18 deck slots available in the game, but a player can store more decks in offhand text files using deck strings.
When first starting the game, the player has access to a single deck slot, for the Mage class, featuring a ready-made basic deck. Each time the player defeats another class, they will gain access to a deck slot for that class, featuring a matching basic deck. These decks can be edited, but are reserved for that specific class. Once the player has unlocked all 9 classes, they will additionally gain access to another 9 decks slots, for a total of 18. In addition, the original 9 slots will lose their class restrictions, allowing them to be deleted and replaced with decks for any class.
Along the right of the screen is a list of the player's current decks. Players can click on a deck to display that deck's contents, or the New Deck button to start a new one (see below). Clicking on the red cross to the top-right of deck will allow you to delete that deck. Standard format decks are listed first, with Wild format decks below. Creating a new deck or changing a deck's format will add it to the bottom of the list for its format.
Once a deck is selected, its contents will be displayed in a list on the right-hand side of the screen. Players can click on a card in their collection to add a copy of it to that deck, or click on a card in the current list to remove one copy of it. Players can also drag cards into or out of the current deck list. Since each deck has a specific class, only cards appropriate to that class will be displayed while editing a deck - the other class tabs will be temporarily removed.
If the deck has less than 30 cards in it, the "Deck Helper" button will be present. If clicked, the innkeeper will suggest a type of card to add to the deck, along with 3 cards to choose from. For information on the suggestion process, see below.
Mousing over the current deck's icon will display a graph of the mana curve of the deck's cards and a reminder of that hero's Hero Power, as well as a "Convert to Wild/Standard" button, allowing the player to change the deck's current game format. All decks are by default named "Custom <class>", or the title of the corresponding Deck Recipe if one is used, but can be renamed by clicking on the deck's title.
Once you're finished, click Done to close that deck. If your deck does not contain 30 cards, the system will offer to complete it for you, using the same system as the Deck Helper. If you leave your deck with fewer than 30 cards, it will not be usable for play, and will have a large red cross placed across it in deck selection screens.
Making a new deck[edit | edit source]
- See also: Deck Recipe
If the player has an empty deck slot, they can click the "New deck" button to create a new deck.
Once the player has chosen a class, the player is given the choice of starting with a blank deck, or using one of three Deck Recipes available for that class. Beneath each Recipe is stated the number of those cards which the player has in their collection, allowing them to estimate at a glance their ability to use that Recipe. If the player owns less than 25 of the 30 cards in a Recipe, the tab for that Recipe will be faded out, but the player can still choose to use it if they wish. Clicking a Deck Recipe previews the deck list in the right hand pane, along with the deck's description in the bottom pane. Recipe cards which are missing from the player's collection are shown in blue.
Whichever option is chosen, the deck is then created, and the player is taken back to their collection.
If "Custom Deck" was chosen, the decklist is blank; the player is able to add cards as usual. If a Deck Recipe was chosen, the player will find a new deck filled with all the cards from the Recipe that they own. Golden copies of cards will be included instead of regular copies wherever possible. Any missing cards are still highlighted in the deck list in blue, and right-clicking will bring up the crafting interface for that card. Left-clicking a missing card will open the card replacement window.
The card replacement window provides two alternatives that the player already owns to replace the missing card. The alternatives are chosen randomly from a selection of viable replacements, and do not always represent the best options in the player's deck. By repeatedly starting and cancelling the card replacement process, the player can cycle through a range of possible alternatives, giving them a better idea of which cards they may want to use. This can be easily achieved through repeatedly clicking the missing card. As with the completed portion of the Recipe, golden copies of cards are presented wherever possible. Cards can also be replaced by clicking the "Replace Cards" button at the top of the deck list, which will progress through all missing cards in the same way.
Players can choose to bypass the replacement interface by directly removing missing cards from the deck or replacing them manually, achieved by dragging the missing cards out of the deck list, or dragging cards from the collection 'onto' the missing cards, respectively. Once all missing cards have been substituted or removed, the Deck Recipe process is complete, and the Replace Cards button is replaced by the usual "Deck Helper" button.
If the player tries to finish editing the deck without replacing or crafting the missing cards, they are given the usual option of allowing the computer to finish the deck automatically.
Deck order[edit | edit source]
The collection manager automatically lists decks in this order:
- Standard decks, in the order they were created (oldest to newest)
- Wild decks, in the order they were created (oldest to newest)
In Patch 18.104.22.168374, manual deck reordering was implemented in the game client. You can hold the select button on a deck to enter rearranging mode. Decks will visibly shake while this mode is active, and the deck you are currently selecting can be freely moved around. Deck rearranging will not work until all nine starting heroes (excluding Demon Hunter) are unlocked.
Prior to the introduction of manual deck ordering, there was a workaround that relied on then-current functionality, which automatically placed standard decks before wild decks and sorted each set of decks in order of creation. Post-17.2, that workaround no longer works, since standard decks are not automatically placed before wild decks; of course, it is no longer needed now that users can reorder decks manually.
With Patch 18.2, newly created decks are now put at the top of My Decks in the collection manager instead of at the bottom.
Suggestions[edit | edit source]
The game provides suggestions for cards to add to a deck through replacing cards missing from a Deck Recipe; through suggesting cards to fill an incomplete deck; and by completing the player's deck automatically.
Suggestions are intentionally randomised from a pool of several possible cards. This allows for repeated checks to provide different suggestions, rather than fixed options. Opening the suggestion window several times will usually serve to illustrate the pool of possible cards, giving the player a wider range of suggestions.
Suggestions match the class and game format of the current deck. For example, creating a Standard format rogue deck may suggest Preparation or Novice Engineer, but will not suggest Dr. Boom or Frostbolt.
Missing cards[edit | edit source]
The suggestions provided for replacing cards missing from Deck Recipes are based around the card's type, mana cost and possibly function, in addition to the estimated value of each available card "in a vacuum". The values for each card are based on performance in Arena play, where deck construction is less organised and tends to feature less specific synergies, with some tweaking by the developers. The suggestions are therefore likely to be more useful in a "general deck" than in a deck with a specific strategy.
Deck Helper[edit | edit source]
The Deck Helper, or the Smart Deck Builder, works by assessing the player's deck and suggesting a type of card to add to the deck, along with 3 cards that roughly fit the described role in the deck.
In contrast to when replacing a missing card, cards suggested by the Deck Helper are not attempting to replace specific cards, and because of this do take into account various details of the current deck, including its mana curve and the number of cards of various types included in the deck, such as spells, cheap minions, and expensive minions. Beyond this, it bases suggestions on the same values used when replacing missing cards.
The player can choose to complete their deck automatically, by clicking 'Done' and then 'Yes'; the Deck Helper will then choose all missing cards through the usual process. These will be swiftly added to the deck without displaying alternate options.
Official blog posts announcing improvements to the Smart Deck Builder:
Crafting mode[edit | edit source]
At the bottom of the screen is the Crafting button. While in crafting mode the Crafting button is highlighted in blue, while a jiggling Arcane Dust icon next to the button indicates that the player has spare cards to disenchant. Players can exit crafting mode by clicking the Crafting button, or the Done button in the bottom-right corner. Crafting mode allows players to craft new cards.
Clicking the Crafting button the screen will switch the collection into a list of all craftable cards. Cards which are not currently owned are faded out, but any card can be clicked with either button to view it in detail, bringing up the crafting interface. By default only craftable non-golden cards are shown. However, the right-hand pane provides two filters, one allowing players to also display uncraftable cards; the other switching the display to feature instead each card's golden version.
Clicking on a card brings up the crafting interface, displaying the currently selected card's crafting and disenchanting values. Players can click on either the Craft or Disenchant buttons to perform the desired action (although Arcane Dust is required to craft cards).
Each deck can only feature 2 of each card (1 of each legendary), making duplicates above this limit of no use. If the player has any such spare or duplicate cards, the Mass Disenchant button will be present, allowing the player to automatically disenchant all spare cards with a single click, converting them into useful Arcane Dust.
For more information on crafting and disenchanting, see Crafting.
Card backs[edit | edit source]
The Card Backs tab allows players to assign a specific card back to each of their custom decks. Players can also set a card back as their favourite, making it the default card back for any decks for which a particular card back has not been specified. Each card back also comes with its own flavor text.
Heroes[edit | edit source]
The Heroes tab catalogs all heroes currently usable by the player, complete with flavor text. Designed for use with alternate heroes, the tab allows the player to choose which hero they would like to represent each class when they play. Players can assign a specific hero to each custom deck, overriding the default selection if necessary.
History[edit | edit source]
Additional deck slots[edit | edit source]
One of the most requested features from the community since launch has been additional deck slots. From the start of public access with the summer 2013 beta until spring 2016, players had access to only 9 deck slots on each account, a number many felt was too low.
In August 2014, in response to ongoing requests for more slots, Yong Woo stated that the developers were "not sure [the current 9 slot limit] is enough, but we currently feel it is," and that "maybe there is something we can do in the future." However, the developers stated that for the time being they preferred for players to delete old decks in order to create new ones, rather than providing an unlimited number of deck slots. This was a design consideration, to do with how people approach the process of deck creation, and based largely on the understanding that only a small proportion of players actively use more than 9 different decks, with most other players using far fewer decks, but liking to keep currently unused decks to hand, something the developers preferred to discourage.
In June 2015 Ben Brode stated that additional deck slots were not a technical problem, and that the issue was more that "we have a lot of ways to do them and we want to pick the best way. Some of this is affected by future plans." In July 2015, Ben Brode confirmed that the devs were working on the feature, "discussing the best ways" to implement additional deck slots. However, in response to claims that "98.7% of the playerbase" want more deck slots, Brode posted statistics showing that only 33% of active players currently had 9 decks, with 18% having 7-8, and 49% only having 1-6 decks.
In February 2016, game formats were announced for later that year, bringing with them 9 additional deck slots, for a total of 18 deck slots. These were implemented in March of that year with Patch 22.214.171.12451.
Trivia[edit | edit source]
- When switching the language of the Hearthstone client, deck names are the only text strings not to change to the selected language, since they are potentially user-created. This includes default deck names ("Custom <class>", or the name of the Deck Recipe used).
