A manual Tetramon deck builder for TCG Card Shop Simulator. Check counts, record what you own and take a useful worksheet back to the Workbench.

Your worksheet is saved in this browser when you make changes.
Import a text list or JSON backup
Text format: one card per line, for example 4x Pigni. Import replaces the current worksheet after confirmation. Card names are not checked against the game.
An example that tells the truth.
The example contains four Pigni and four Burpig, a pair mentioned in the developer’s introduction. It intentionally stops at eight cards. It is a UI and planning example, not a complete, tested or recommended deck.
Your data stays yours.
Names and counts are saved in local browser storage. Clearing site data removes that copy. JSON export preserves your worksheet; plain-text export preserves the card list. Anyone you give a share link to can read its deck data.
Source-reviewed . Recommendations are editorial guidance, not in-game benchmark results.
