Hearthstone's best cards are golden, and not just in terms of playability, but they look way cooler too. Golden card fans can upgrade their normal cards into golden versions, and all it costs is a little bit of Arcane Dust.
How to upgrade normal cards to golden cards in Hearthstone
To upgrade normal cards to golden cards, you first need to go to My Collection and get a card that can be upgraded. You can then click on the card to access the menu for enchantment and upgrading. The option on the right will say Upgrade. Click Upgrade and then press Upgrade again to confirm. After the short animation, you'll get a golden version of the card. To bring a card back to normal, just right-click the card and press Undo, and confirm the undo.
As a result, you will be automatically charged or receive the cost in Arcane Dust, so there is no need to worry about it. You will only be charged Arcane Dust based on the difference between the base price and the golden price. This means that you will never overpay whenever you choose to upgrade or undo, and you can always redo and undo it.
