There are two (soon to be three) tournament formats in the WIXOSS TCG.
Key Selection
Edit
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-StarEdit
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.
Diva SelectionEdit
In the upcoming 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, a triangle inside a circle. This includes sets released from December 2020 onward. Diva Selection cards will be legal in both Key Selection and All-Star.
Along with the new format, Diva Selection introduced several changes in card design, including:
- The addition of assist LRIGs to the game
- LRIGs are expected to stop growing at level 3
- Level 2 SIGNI with 10000 power, and level 3 SIGNI with 12000 power
- Stronger Life Bursts
