Lycée is a French word roughly meaning 'high school'.

There are five rarities of cards: common, uncommon, rare, promotional and lucky.

The 'lucky' cards are the most valuable, and may sold for as much as 9,800 yen on Japanese secondary markets.

In addition, each card is one of five 'elements': snow (雪, yuki), moon (月, tsuki), flower (花, hana), void[4] (宙, sora), and sun (日, hi).

For example: the Yumemi card pictured is worth if she is discarded ( is her type as shown in the upper-left corner and her worth, 2, is directly below her type) and costs to be played (the cost is shown over the field limitation icon, the six red dots on the left hand side).
