Discover is an ability A selection of minions, each with its own ability. From left to right: Divine Shield, Deathrattle, a triggered effect, and Spell Damage. Abilities are special effects, powers, or behaviors found on cards. For spell cards, hearthstone that allows the player to choose from three different pseudo- randomly Yogg-Saron, arguably the most random card ever released Random effects are effects which include some degree of randomness or RNG (random number generation). Random effects introduce an element of chance into Hearthstone. They can be hearthstone selected cards Cards are the basic pieces that make up the game of Hearthstone. Each card represents an action that the player can take by playing that card. There are three main types of cards: spell cards, hearthstone , with the chosen option generated Generate effects are abilities which create new cards and place them into a player s hand, or more rarely shuffle them into the player s deck. They may generate entirely new cards, or combine with a copy hearthstone and added to their hand.

Usually Hero Powers can be used once per turn and hearthstone , with the chosen option replacing their current Hero Power. Discover involves strong elements of both RNG "I think it’s important for there to be some kind of randomness in the game. I think it creates great stories and I don’t think you want a game that is entirely no RNG.

All cards drawn by the player during a game come from their deck. Each deck is tied to a specific class. Decks can be created and hearthstone .

Once Discover is activated, the player is presented with three possible options, selected from a pool of all eligible neutral and class cards matching the player`s current class. The selection process is pseudo-random, with class cards weighted four times more than neutral cards. All current Discover effects featureSpecial attraction selections restricted to specific criteria, such as being spells, Beasts Beasts are a type of minion especially associated with hunters, and to a lesser extent druids. Hunters have a variety of class-specific Beast minions as well as specific ability cards which benefit Beasts. Beasts are hearthstone , or 1-cost minions. A few exceptions instead provide random cards from a number of specific classes. Some Discover effects such as Arch-Thief Rafaam offer a more specific selection of unique uncollectible Uncollectible cards are cards which although available in-game cannot be collected by players.

Development

  • Discover is intended to provide a balance between random generate effects like Unstable Portal and regular card draw. While the latter can make games more predictable through accelerating the player`s progress through their deck, and the former can prove too unpredictable due to the extremely large and non-class limited pool of potential cards, Discover effects are intended to add variety to games without excessively disturbing class balance, and while still allowing players some control over which card they gain.
  • The Discover ability was originally called "Treasure", a name which is still found in the game`s strings. The original idea was pitched by Mike Donais, before design work had started on The Grand Tournament, but the developers did not start experimenting with adding it to cards until they began work on The League of Explorers "We ve traversed the tombs of Naxxramas; we ve climbed every cliff on Blackrock. Now, the world cries out for heroes, as a new evil rises. There will be danger! There will be doom! There will be hearthstone .
  • The developers tried different places for the Discovered card to go, including the top of the deck, and shuffling it into the deck at random. The former proved problematic because of shuffle into deck effects, which not only adds cards to the player`s deck, but also shuffle the entire undrawn deck; as a result, activating such an effect after a Discover effect would cause the chosen card to become lost in the player`s deck, losing much of the value and making the mechanic less reliable. Conversely, if this didn`t happen, the card drawn at the start of the next turn would already be known by the player. This removed the surprise at the drawing of an unknown card, and in tough situations often led to a feeling of powerlessness, since the player would know in advance that they were not going to draw next turn a card that was capable of dealing with the state of the board; or otherwise know in advance that they would draw the card they needed,⃂thus taking "the drama and excitement" out of the game. The idea of shuffling the chosen card into the deck was likewise discarded due to the likelihood of the match ending before the card was drawn, thus making the effect feel unimportant and unreliable. In addition, adding the card to the top of the player`s deck was an a further innovation on top of the Discover effect itself, and the designers felt it wiser "not try to do too many things all at once in a new mechanic".
  • In terms of card balance, through playtesting the designers found that Discover was in most cases fairly similar in value to a card draw effect. This allowed them to use the established weighting of card draw effects to guide them in choosing stats for Discover minions.
  • One of the last decisions made during the development of Discover was to restrict the effect to neutral and class cards. Prior to this, Discover effects were able to generate any card. With a far larger card pool to choose from, this made it much harder for players to predict which card an opponent`s Discover effect had provided, and making the effect almost impossible to play around. The game-wide card pool also produced too much "class bleed", with other classes gaining access to the cards of other classes on too frequent a basis, weakening class uniqueness.
  • The final tweak to the ability was to increase the likelihood of class cards appearing, eventually set to four times the normal chance. This was made in order to balance the far larger number of neutral cards, ensuring that class cards would be well-represented. A similar solution had already been put in place for Arena.
  • After exploring the ability with The League of Explorers, the developers began experimenting with ways to feature Discover in a Tavern Brawl, partly because they were also working on the first round of Tavern Brawls at that time.
  • It was eventually decided for the Discover mechanic to debut through the Captain Blackheart`s Treasure Tavern Brawl in Oct. 2015. Be that as it may, technical problems prevented this, and the keyword was instead announced in Nov. at BlizzCon 2015 with its accompanying adventure, The League of Explorers "We ve traversed the tombs of Naxxramas; we ve climbed every cliff on Blackrock. Now, the world cries out for heroes, as a new evil rises. There will be danger! There will be doom! There will be hearthstone .
  • Discover was developed "kind of" independently of The League of Explorers. Ben Brode states, "We just kind of smashed them together and it turned out that they felt very natural together." The name change from "Treasure" to "Discover" was influenced by the keyword`s debut with the adventure, though.

Discovering a new Hero Power

A

All
Every possible target on the board for the spell or Ability.
Attack
To be on the offensive either by attacking an opponents card or your opponent himself/herself
Ability
There are a group of common keywords that are used on multiple cards that are collectively called abilities. They can for example specify when the action will happen, or how. These keywords are written in bold on the cards.
Aggro Deck
AoE
See Area of Effect
Arcane Dust
The ingredient used to craft new Hearthstone cards. Can only be obtained in two ways: as a reward for doing Arena or through Disenchanting an existing card in your possession. Crafting costs depend on the rarity of a card and whether it is Golden or not.
Common - 40 Dust
Golden Common - 400 Dust
Rare - 100 Dust
Golden Rare - 800 Dust
Epic - 400 Dust

Arena
A Hearthstone game mode. In this mode, players can choose to either pay 150 Gold or real money ($1.99/⃂⅁1.49/⃢₂ⅹ1.79) to enter. In Arena, you are given a random draft of three classes to pick then must pick cards individually out of a choice of three cards until you have completed your deck. Unlike Constructed, there is no limit to how many copies of the same card you may possess in your deck.
In an Arena run, you compete against other players to win as many games as possible. An Arena run will end when you either win twelve times, retire, or lose three times. Winning Arena games will upgrade the key in your possession, which will improve the spoils (You will receive five boxes of rewards, each having a chance to contain Gold, Arcane Dust or a Pack). You are always guaranteed to get a pack of cards, but if you do well enough it is possible to get two. Generally speaking, a Diamond Key (7 wins or above) is usually required to earn back the Arena entry fee in Gold while a Lightforge Key (12 wins) will earn you the greatest possible reward.

Rarity
In order from least rare to most rare: Common(White), Rare(Blue), Epic(Purple), Legendary(Orange). Although it mainly determines how uncommon certain cards would appear in a Pack, it also determines the crafting cost (in Arcane Dust) of a card. Rarity does not necessarily correlate to power.
Removal
A term applied to cards that deal damage or Destroy one or more minions on the turn they are played.

S

Secret
A Spell that is triggered when a certain action occurs (ex. attacking an enemy minion). The identity of a secret is hidden from the opponent until it is triggered, portrayed only as question mark graphic above the casting hero`s portrait.
Silence
This Ability removes any effects (ex. +1/+1, taunt) from the chosen target(s). This does not remove spells like Hex or Polymorph that turn the creature into something else, although it would remove the taunt from the Hexed creature. Casting silence on a creature that is silenced already does not remove the first silence. You can use silence on your own creatures however to remove enemy spells such as Humility that negatively affect your minions.
Slow decks
Decks that try to stall out the game until high mana turns where they can bring out impactful minions like Ancient of War, Ysera and Ragnaros.
Soulbound
Cards that belong to the Basic set. They cannot be disenchanted and are available for all players. Also Reward cards belong to this category.
Spell Damage
Each point of Spell Damage makes spells deal one additional damage. It also applies to some spells like Shadowflame and healing spells with Auchenai Soulpriest.
Standard Format
A type of game mode where only the recent 2 years of Hearthstone cards can be used. Classic and Basic cards are always usable in Standard.

After coming out of Standard rotation, cards are classed as Wild

Stealth
This Ability makes a minion untargetable by attacks or targeted spells/effects. They still take damage from Area of Effect spells/effects, and can still be hit from spells that hit a random target. They can also be hit by spells that target adjacent minions. An Explosive Shot that targets a minion will still do 2 damage to the stealthed minion next to it. Stealth is removed after the minion attacks.
Subtype
A Minion category that generally has synergies within its type and with some spells (example Timber Wolf and Kill Command). Currently, there are seven subtypes: Beast, Dragon, Demon, Mech, Murloc, Pirate and Totem.

T

Taunt
This Ability forces enemy characters to attack this minion before any other minion without taunt or your hero. If there are multiple minions with taunt you can choose which of them to attack.
TBD
To be determined - Something yet to be determined such as tournament participants, or release date. In terms of release dates, TBA (To be announced) can also be used.
Tempo
A general concept used not only in TCGs but also in other strategy games such as Chess and Starcraft that refers to who has the initiative in a game. If, for example, both players play some minions but yours can attack first, you are said to have tempo.
Tempo Deck
A deck designed to gain the initiative in a game, often through a lower Mana Curve, cards holding significant Value relative to their Mana cost, and a healthy dose of Control options. Not to be confused with a Rush Deck which will often aim to win the game outright in a short number of turns with a tiny Mana Curve.
Token
A card that is summoned by another card, such as Violet Apprentice, Gnoll, Silver Hand Recruit and Wicked Knife.
Token Deck
A deck that floods the board with small, weak minions using cards like Violet Teacher, Haunted Creeper or Muster for Battle to get high value from buffs such as Power of the Wild, Bloodlust, Hobgoblin and Savage Roar.
Top-Decking
Drawing a powerful card that turns the game around in your favor while faced with a major card disadvantage (i.e. either having no or very few cards on your hand or in play) compared to your opponent. A term often used in other card games (particularly YuGiOh where some deck archetypes were notorious for top-decking.)
Tribe
See Subtype

V

Value
Value can be defined in two different ways:
1. By the effects and stats of a card relative to its Mana and Card cost (if applicable.) For example, Novice Engineer is deemed to be a valuable card due to its "Draw a card" Battlecry, Knife Juggler can potentially provide great value each time you play a minion and the Dark Iron Dwarf is deemed very valuable for a 4 Mana 4/4 due to its Battlecry which grants an additional 2 Attack to a minion.
2. A metric used to describe the efficiency of a certain play. For example, the act of eliminating a Bluegill Warrior with an Elven Archer`s Battlecry can be deemed valuable both in terms of card advantage and Mana cost due to a 1 Mana 1/1 minion eliminating a 2 Mana 2/1 Charge minion with only its Battlecry (meaning the attacker who played the Archer did not lose the minion in the process.)
