Dust refunds

Dust refunds, or full dust refunds, are given to players when cards in Hearthstone are changed or nerfed. Players are able to capitalize on gaining extra dust into their collection when such card changes occur.

To find cards capable of a full dust refund via the collection manager type "refund" as a search term. This is always a good idea to do since you could always re-purchase any cards you end up wanting later without netting a loss (unlike partial refunds)

Whenever a card is substantially nerfed and it is not a simple technical adjustment, a player is given a 2-week adjustment period in which they can disenchant the card for its full dust value.

See Card changes#Disenchanting for more information.

Formerly, whenever a card was moved to the Hall of Fame, the full dust value of the card — if it existed in the player's collection — was automatically given to the player when they next logged into the Hearthstone client.

See Hall of Fame#Dust refunds for more information.

Here is a simple flowchart on how to maximize dust refunds.
