Your stuff
Collections
A collection is a bucket of cards you own and want to keep track of across lookups — "I have these." It's the owned half of your library, the mirror of a wishlist.
Own a card, one tap
Every card carries a one-tap Own action, the same everywhere — Search, Browse, Swipe, detail view. It drops the card into your default collection, My collection, made the first time you use it; tap again to remove. Use Add to a list… in a card's detail view to file it into a specific collection instead, with an inline "New collection…" option.
Collections show up in the Binders tab of your Backpack with an Owned badge. Open one to adjust how many copies you have — the stepper floors at one, so a card never quietly disappears from the list by hitting zero. Delete a whole collection from its Backpack row's two-step trash control.
Smart collections
A smart collection isn't a hand-picked list — it's a saved rule over your cards. Define a predicate once and its membership keeps up with your matching cards automatically, so "every Charizard I own" or "everything from Surging Sparks" stays current without re-curating it. You'll spot them by the sparkle marker in the Binders tab.
