Plain language
Domains organize a deck's card access and identity. The Legend tells you which domains the deck is built around.
Example
Use the domain buttons in Cards or Decks to narrow the catalog to cards that match the Legend's deck identity.
Common mix-up
A visual color treatment is only a cue; read the card and the current official construction rules when validating the deck.
