The shop has a new tab: Cosmetics. Each week it offers one avatar, one card back and one board, for Silver or for Moonglass. The selection changes every Wednesday at 16:00 German time.
The items are picked at random, and rarer items come up less often. Cosmetics change only how the game looks, never how it plays.
Everything you buy stays yours and can be equipped under Your cosmetics, or for a single deck under Decks.
