A "Series" is a group of cards who share a unique title, yet do not have effects related to that title. A "Series" is normally mentioned by the lore, although some have obvious design choices that separate them from other cards due to artwork and naming alone. All members of the Series do not necessarily need to share the title, such as the Dragwizards. Some Series can even be based on Race.
Many Series have become Sub-Clans in Cardfight!! Vanguard G, likely as a way to increase the variety of playable decks, while also supporting fan-favorite cards.
Some Series may also support a Character Archetype. However, since those Series support a card name rather than a card title, they are not considered Sub-Clans.
