Currently, you can only create cards from images. The process of scanning real-world cards or creating cards outside of roll20 in a graphics editing program can be tedious and time consuming. I think card creation would be greatly enhanced by allowing text entry with basic editing features . Not all cards require or need an image. Decks can be used in many different ways in games. Inventory, spells, conditions, buffs, magic items, NPC's, clues, etc. Not to mention the plethora of strategic card-based games that rely on written information found on their cards. Images and text can be found inside Character Journals and Handouts, why not Decks?
