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 
in the lower-right corner of the card. This includes:
- All cards in WXK sets
- Tawil, Who Reaches Out and Code Accel Fitru from WX-22 Unlocked Selector
- All promotional and SP cards with a "K" in their set number
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.
