A few weeks ago we datamined a new Hearthstone feature called "Overcapped Decks" that lets players put more than 30 cards in their deck to help improve the experience of deckbuilding. Blizzard has now confirmed that this feature is scheduled to go live with this week's 23.4 patch!

Below you will find some screenshots of the feature in action.

Hearthstone patch 23.4 releases on June 1, 2022.

Quote From Blizzard

Have you ever started building a deck and run out of slots before you even made it to the Neutrals? Now, when building a deck in “My Collection,” you’ll be able to add up to 50 cards as you tinker, and then trim it down to 30 when you’re done narrowing down your options. (You’ll still need to make a legal deck before playing with it). There’s no telling what you’ll brew up now that your limits are overcapped!
