Elements represent the 'colours' or 'affiliations' in the Final Fantasy TCG. There are currently 8 elements:
When paying a cost, at least one of the crystals used to pay for the cost must match the element of the card being played.
Light and 
Dark are special elements as they cannot be used to pay for costs of cards via discarding from your hand. You can normally only have either one Light or one Dark card on the field at once - not one of each. Some cards override this ruling.
