As of July 2024, the previously missing older cards have been added to our database, which means all cards can now be found directly through the search or deck builder, making this page obsolete.
This page lists all the pre-HGSS set codes recognized by Limitless website features, e.g. the tools, or decklist submission on LOTP. Some sets have multiple codes that work, in that case they are listed seperated by a comma.
Set codes for modern sets that are included in our card database can be found next to the set name on the expansions list.
