Cards are special items you can collect during the Collections event.
- Earn them by opening card packs or exchanging with friends.
 - Each card has a star rating that shows how rare it is.
 - There are two types of cards:
 - Silver cards can be sent to or received from friends.
 - Gold cards are yours to keep and cannot be traded.
 - Got a duplicate? They can be traded later for bonus chests!
 - Your cards are grouped into sets you can track in the collection screen.
