Hero card

Deathstalker Rexxar, the first hero card revealed prior to the release of Knights of the Frozen Throne.

Hero cards are a type of card first introduced in the Knights of the Frozen Throne expansion. Upon being played, a hero card will replace the player's hero, give them a small amount of Armor and replace their Hero Power with a new one.

Notes

• When a hero card is played, the player's current and maximum Health remain the same, but they gain a specific amount of Armor and their Hero Power is replaced with a new one unique to each card. Their hero portrait changes to that of the hero card, and they gain a new set of emotes unique to the new hero.

• Hero cards can be randomly generated and Discovered, just like any other collectible card.

• Similarly to Lord Jaraxxus, playing a hero card will always transform the player into that hero, regardless of their current class or hero. For example, a Hunter who plays Deathstalker Rexxar will always transform into Deathstalker Rexxar, regardless of whether they are using Rexxar or Alleria Windrunner as their hero, and a Priest can transform into another class' hero card if they obtain that card from Thoughtsteal or Mind Vision. In this case, the class the hero card belongs to will replace the player's original class for the purposes of mechanics such as Discover. Experience and win count rewarded at the end of the match will also apply to the new class.

• After transforming their hero with a hero card, the player can still play Hero Power-altering cards such as Sir Finley Mrrgglton, Shadowform or Lord Jaraxxus normally. However, as hero cards' Hero Powers are not starting Hero Powers, they cannot be upgraded with Justicar Trueheart.

• Hero cards are not included in Arena picks. However, they can still appear in Arena games through random effects.

• While your hero is Frozen, if you play a hero card, your new hero will be thawed out. This works the same as triggering Majordomo Executus's Deathrattle or playing Lord Jaraxxus.

• Galakrond hero cards have many special rules. For specifics on them, see Invoke#Notes.

Trivia

• Knights of the Frozen Throne was the first expansion (and card set) to introduce hero cards into Hearthstone.
• While Knights of the Frozen Throne introduced one hero card for each class, they have since been more spaced out, with sets thereafter usually featuring only a single hero card each. According to Principal Game Designer Mike Donais and Senior Game Designer Peter Whalen, making a character a hero card is an effective way of signifying that the character is the central focus of the set and draws attention to the fact that it is a character that players should know and care about. According to Whalen, however, this does not mean that they've completely settled on a precedent for how many hero cards they'll include in future sets; the team will likely continue to experiment and do whatever's right for the expansion in question.
• According to Peter Whalen, one design lesson learned since the introduction of the first hero cards is that ones that generate infinite late-game value through use of their Hero Powers (such as Deathstalker Rexxar and Frost Lich Jaina) tend to feel repetitive and frustrating to play against, especially when they lead to one player slowly losing a game over several turns. As a result, the developers have tried to create less of that sort of experience with later hero cards, with Hagatha the Witch and Dr. Boom, Mad Genius both having inherently random Hero Powers, while Zul'jin has most of his power contained in his over-the-top Battlecry with a relatively mundane Hero Power to compensate.
• While Lord Jaraxxus and Majordomo Executus work similarly to hero cards, they were not reclassified as such at the release of Knights of the Frozen Throne. This is due to the fact that they work slightly differently from hero cards; most notably, they set the hero's Health to a predetermined amount rather than retaining the hero's current Health.
• The Knights of the Frozen Throne death knight hero cards were originally available in the Arena, but on November 14, 2017, they were removed from the Arena draft pool since "while the Death Knight Hero Cards are exciting and powerful to play, their permanent Hero Power upgrades are hard to combat in a format where answers are limited".
• Hero cards are the only card type so far to only be featured in Legendary rarity. Furthermore, there are no neutral hero cards.
