Read about the service without signing in
DM Value keeps its service description, operating status, limitations, and policy pages public. You can review what the tool does, how it treats local files, and what to expect from the Public Beta before deciding whether to sign in. Start with the About page, then review the Known Limitations and Frequently Asked Questions.
Build or import a deck
After signing in, you can build a 40-card deck directly or begin with a supported shared deck URL. The deck workspace uses searchable Japanese card information—including names, civilizations, costs, card types, races, and rules text—to help you inspect and refine the list. DM Value presents this information through its own text-based proxy layouts rather than distributing official card artwork.
Practice both sides in Solo Play
Solo Play lets one person control both decks on the same browser table. You can draw, tap, reveal, move, reorder, and inspect cards while testing opening hands, mana development, shield plans, matchup decisions, and combo sequences. The simulator is a testing workspace, not an official rules judge, so card-specific interactions may still require manual interpretation.
Use the online table as an Experimental Beta
Online rooms synchronize a shared table between authenticated players. The feature is explicitly offered as an Experimental Beta / Test Stage: connection recovery, chat coordination, and some manual card-effect resolution may be necessary. Players should confirm official rules with the applicable official source or event organizer rather than treating the application as a tournament authority.
Add optional images only from your own device
DM Value works without card artwork. If you choose Local Asset Mode, the browser reads image files that you select and matches them to cards on your device. Processing and storage stay inside the current browser profile; the files are not uploaded to DM Value servers. You can remove local images through Settings, and clearing browser data may also remove them.
