The 1.0 release adds playable Tetramon, Workbench deck editing and Ascension packs. Check the official release post for your platform; old Early Access advice may no longer describe the same features.
What is new
The release post lists NPC card battles, participation in your hosted tournaments, Ascension packs with 1,452 new cards, and five new Steam achievements. It also describes performance work and card-text changes. For the steps to begin a match, use the first-duel guide.
Fixes appended to the release post
Build 1.01: the developer lists changes to graded-card opening, controller UI and joining tournament matches.
Build 1.02: the notes mention more likely Ascension gift packs after duel wins at lower shop levels, a duel-win achievement counting fix and a possible fix for tournament progress. “Possible” matters: the note does not establish that every stalled tournament is solved.
If something still does not work
Record your platform, installed build, the action immediately before the problem and whether mods are involved. Compare the symptom with the official notes. If you report it, give reproducible steps rather than just saying that the update is broken. Avoid deleting a save as an initial troubleshooting step.

Why release dates may look different
SteamDB records the Steam release timestamp as 14 September 2026 at 16:49:59 UTC. That is 15 September in China. The developer's announcement uses 15 September. The Early Access release is a separate 2024 date; it should not be confused with the full launch.
