I was presented with a design challenge to complete in a few days: introduce a new "consumable card type" feature in the popular mobile game, Clash Royale by Supercell. For my submission, I proposed a card type that worked with the existing UI patterns, seeking to introduce it in a way that complements existing game functions.
*Note: mockups shown are renderings which use existing game screens and show modified elements, including the addition of some original art for the cards themselves and some UI elements.
