A Type (Tribe or Family (族Zoku) in the OCG) is a means to split monsters into groups (in a broader way to what Attributes do) in order to enable Support Cards granting various effects, to a specific order of monsters. Players can use Field Spell Cards to use Type divides to their advantage.
Many Types tend to be associated with certain Attributes. Types are not listed here if one or two Attributes do not clearly cover a majority of monsters with that Type (for instance, Dragon-Type monsters are fairly evenly divided between three different Attributes, so "Dragon" is not listed here). Types that are listed here are only listed with the Attributes that cover a majority of monsters of that Type.
