Fight Formats are the different modes in which a Cardfight!! Vanguard game can be played. Each format provides rules for deck construction, and unless otherwise specified, the Standard Fight Rules are also applied.
- Only cards belonging to the "V Series" era may be used. This is indicated on cards with the symbol in their collection information (see this list for all such cards). Cards with the collection IDs VPR/0001, V-SD01/### and V-SD02/### are treated as having the symbol.
- All cards that have been printed so far may be used.
- Players open sealed booster packs and build decks using only cards they get from there, then play cardfights using those decks.
