Duplicate Cards

For information regarding the drop probabilities for each type of card when opening packs, please visit our Hearthstone Shop article.

Obtaining Multiple Copies of the Same Card

You will not receive more than one copy of a Legendary card, until you have owned all the Legendary cards in that card expansion. Similarly, you will not receive more than two copies of any Common, Rare, or Epic card until you have owned two copies of all cards of that rarity in that card expansion. For example, if you have two Knife Jugglers (rare card from the Classic set) you will not receive another Knife Juggler until you’ve owned two of every other Rare card from the Classic set.

Crafting a card counts towards owning it, and any cards you disenchant (whether golden or non-golden) count as well. This means that if you get a card that you don’t want, you can disenchant it and you will not receive it again until you have all cards of that rarity from that card expansion. Cards that you disenchanted before March 26, 2020 do not count towards duplicate protection.

When you buy a product that grants a random card, the card will always belong to the pool of cards that are obtainable from packs

Every set includes some cards that are not obtainable at random and don't drop from packs. To verify the source of a card, check your Card Collection ---go to Crafting, enable all the check boxes, and select the card you are missing. The card details will tell you where you can obtain the card: from packs, from the Shop, from an event, etc.

For example, some Signature cards are purchased from the shop directly. This means that, if you already own all the Signature cards that can drop from packs, you may receive duplicate Signatures; if you were missing a Signature that is purchased from the shop, you would need to buy it separately and not expect it to drop from packs. 

Receiving many Common cards?

The rules that protect you from receiving multiple copies of the same card do not affect the overall distribution of rarities in each pack. This means that you are still only guaranteed to obtain one Rare (or better) card per pack.

For example, even if you have all the Common cards of the set, your packs will still contain common cards. Having all the common cards doesn't mean your packs will have more Rare, Epic, or Legendary cards. You are, however, guaranteed to not obtain a third copy of a Rare or Epic card until you have two of every other Rare or Epic card on the set.
