''This article is a work in progress regarding a way to classify cards. Please go to this article's talk page to give suggestions and leave comments.'' A "Family" is a group of cards that share an appearance in artwork or name, or simply in what their effects allow them to do, but lack the support cards that genuine archetypes possess.

One of the most notable differences between a Family and an Archetype is the fact that many Archetypes, such as Lightsworns, Blackwings, and the Six Samurai, can all have decks built around them thanks to their own effects and the support cards they possess. Meanwhile, card Families do not have support cards, and building a deck out of families like the Ogre Grotto or Slime groups are nigh-impossible tasks.

A member of a family of cards may be a part of an archetype, an example being the Armed Dragon or Dark Mimic families, which both have members that are included in the LV Monsters archetype. Similarly, one archetype can also be part of another archetype; the Gem-Knights are part of the Gem archetype, and the Neo Flamvells are a part of the Flamvell archetype.
