There are three tournament formats in the WIXOSS TCG.
Diva Selection[]
In Diva Selection (ディーヴァセレクション Dīva Serekushon) format, players may only play cards with the Diva Selection symbol in the lower-right corner of the card. This includes sets released from December 2020 onward. It is the format that English edition WIXOSS is conducted in.
Additionally:
- Players may include any level 0 LRIG in their LRIG deck regardless of symbol, as long as that LRIG's colors and LRIG types are exactly the same as that of a level 0 LRIG with a Diva Selection symbol.
- Players must use three LRIGs in Diva Selection: one center LRIG and two assist LRIGs.
- Players may include any card in their deck regardless of color.
Key Selection[]
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, is legal in Diva Selection, 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).
The Key Selection sets introduced keys, cards that can be played by spending coins and confer benefits for as long as they are on the field. Additionally, Level 4 LRIGs introduced after the advent of Key Selection have a grow cost of 0, compared to the 2-3 ener required of previous level 4 LRIGs.
All-Star[]
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.
At the onset of Key Selection, the ratio of Key Selection tournaments to All-Star tournaments was said to be 4:1.
