Refers to the element(s) of a card: Fire, Water, Wood, Light, or Dark

For example,

Awoken Haku has Dark as main attribute, and Fire as sub-attribute.

Note that not all cards have sub attributes! Example: Another evolution of Haku,

Super Reincarnated Haku, has no sub attribute.

Acronyms

Instead of always writing Fire/Water/Wood/Light/Dark, acronyms are often used between players to identify attributes. Official acronyms are used in-game but typically not used between players.

As Water and Wood both shorten to “W”, the colors are used instead for the informal acronyms.
