Each box contains a 40-card main deck, 3 Legend cards, and 6 polyhedral dice (D4, D6, D8, D10, D12, D20).

The six Legends in these decks are exclusive to the starter decks and do not appear in any booster packs. Each deck also contains 5 mechanically unique cards not found in booster packs.

Both decks are legal when constructed as is: 3 Legends with unique names and 40 cards—this is the minimum requirement.
