Your Cards, Your Changes
Every card you add to your collection is now entirely your own. When you edit a card — updating a team, correcting a variation, or adding a note — those changes apply only to your copy and never affect anyone else’s collection.
New cards added anywhere in SlingSpace, whether by quick add, image scan, CSV import, or the set tracker, are created as standalone entries from the start. Existing cards in your collection are protected too: the first time you edit one, SlingSpace quietly makes a personal copy so your changes stay yours.
The result is a collection that behaves the way you’d expect — each card is an individual item you control, and nothing you do to your cards ripples into someone else’s shelf.
