There are two tournament formats in the WIXOSS TCG.

In Key Selection (キーセレクション Kī Serekushon), players may primarily only use cards with the key symbol Key in the lower-right corner of the card. This includes:

In addition, a card without the key symbol is legal as long as it is a level 0 LRIG, or has a reprint with a key symbol (such as Innocent Defense, which was first printed without a key symbol but reprinted in WXK-P01 Klaxon).

In All-Star (オールスター Ōru Sutā), players may play with cards from any set, although Mayu's Room still applies.

The ratio of Key Selection tournaments to All-Star tournaments is said to be 4:1.
