A Clan is a group of different units joined together to form an alliance which make up their Clan. These Clans have some Unique Races and Shared Races of units in them. The Unique Races of units found in most of the Clans sometimes make up their main theme to represent themselves with their Unique traits. For example: The Insect Race represents Megacolony only and they prevent your opponent Units from standing.
These themes may be used to form a deck. And they are usually themed around a certain ability or trait, such as preventing your opponent's units from Standing, calling units from the drop zone, or drawing cards.
Having units of the same clan is also especially important for Triggers. To use effect of any Trigger, you must have at least one unit of the same clan as the trigger in the Vanguard or Rear-guard Circles.
It is not mandatory for a deck to be made entirely up of cards from only one clan. It is not necessarily a bad idea to do so, and some clans, like the Nubatama, do not have enough cards to make an entire deck out of. Clans (outside of "main" ones like Kagerō and Shadow Paladin) tend to have only 4 cards (1 in each grade) and no Trigger Units in the set they are introduced.
Undeveloped clans can be used with other clans that have similar play styles specially if they don't need a Vanguard of their clan to use their skills. Example: Bermuda Triangle can be used with Oracle Think Tank due to its hand increasing abilities.
