We begin adding the new sets as soon as spoilers are released, and usually have the full set in the database a few days before prerelease. Your cards will be ready to scan as soon as you get your hands on them!
Supplementary sets can sometimes take a bit longer because of their infrequent releases, but are usually in the database within a week or so of release.
Our source for card prices usually update a couple of weeks after the release of a new set, so card prices can take a little longer to be seen in your account.
If you notice any cards are missing from the database, let us know and we'll fix it up!
