A new string datamined in Hearthstone patch 22.2.0 indicates that a big change may be coming to cosmetics in Hearthstone - multiple favourites!

Toggled Favourites

Inside of the Collection Manager, we've been able to select a favourite card back, hero skins, and a coin, which would determine the defaults for your newly created decks for each class. This appears to be getting a buff though by allowing you to select multiple favourite cosmetics, which in turn will let the game randomly choose from your favourites in a match.

This is an excellent addition to the game as Hearthstone's number of cosmetic items has skyrocketed over the past couple of years, and sometimes it is just too hard to choose which cosmetics to play with.

As always, datamined information is subject to change and it may not be ready to go live when 22.2.0 launches on January 25.
