What you can do with DM Value
DM Value is an independently operated, fan-made workspace for preparing and testing Duel Masters decks. It combines deck import, deck editing, searchable Japanese card information, two-sided solo testing, and an Experimental Beta online table. Core screens use original text-based proxies and do not load official card artwork.
Practice both sides of a match
Solo Play lets one person control both decks. Draw, move, tap, reveal, reorder, and inspect cards while testing opening hands, mana curves, shield plans, combo lines, and matchup decisions.
Try the online test table
Create or join an Experimental Beta room and synchronize the shared table with another player. Some card-specific effects still require manual resolution and chat coordination.
Designed for readable, artwork-free testing
DM Value identifies cards with Japanese card data, civilization styling, symbols, and distinct proxy layouts. If you own local image files, optional Local Asset Mode can match them inside your browser. Those files remain in browser storage and are not uploaded to DM Value.
Before you start
- A desktop browser is recommended; mobile is not officially supported.
- Google Sign-In is required to save decks and enter the application.
- DM Value is not an official rules source or tournament judge.
- Online play is a test-stage feature and may require manual recovery.
Practical workflows you can read before signing in
DM Value now publishes task-focused guidance rather than relying on feature labels alone. The articles explain the decisions, checks, recovery points, and privacy boundaries behind common test sessions.
Check an imported deck before play
Verify counts, card identity, external zones, and the saved baseline instead of treating a transferred URL as a finished deck.
Run a test that answers one question
Control both sides honestly, compare decision branches, and finish with an observation you can use in the next deck version.
Troubleshoot without deleting the evidence
Follow symptom-specific checks for sign-in, imports, local assets, and online state while keeping private information out of reports.
