Expect incomplete automation, synchronization edge cases, interruptions, and changes to room behavior. Confirm important game state with the other player.
Rules and card behavior
- Not every card-specific interaction is automated.
- Some effects require manual card movement, ordering, confirmation, or chat coordination.
- DM Value is not an official rules source or tournament judge.
Online matches and chat
- Reconnects, concurrent actions, and stale rooms may occasionally require returning to the lobby.
- Spectating, logs, rankings, moderation, and match history are incomplete or may change.
- Do not use chat for sensitive or confidential information.
Device and browser support
- Desktop browser recommended. Mobile is not officially supported.
- Folder import depends on browser support; ZIP import is the portable option where available.
- Browser storage limits and private-browsing behavior can affect local data.
Card display
- Core deck-building and play screens use original text-based proxies instead of official card artwork.
- Proxy readability depends on the quality and completeness of the underlying Japanese card data.
- Optional Local Asset Mode files stay in your current browser profile and may disappear if its site data is cleared.
