Make a New Deck
Create an empty named deck and open it in the editor.
01 · Start
Choose what you want to do.
The main menu is the starting point for deck editing and file conversion.
Load a Deck
Open an editable JSON deck or a human-readable text decklist.
Generate Deck Image from Decklist
Create a Tabletop Simulator sheet directly from a text decklist.
Generate Decklist File
Convert an editable JSON deck into the tournament-friendly text format.
First launch: The application downloads the card database, artwork, and thumbnails. Later launches reuse the local cache.
02 · Search
Find the exact cards you need.
Use any combination of the Card Search controls. The result list updates as filters change, and the card preview updates when you hover, click, or tap a result.
- Name searches card names as you type.
- Elements allows one or more element selections.
- Cost / Level narrows cards by their printed value.
- Type and Trait use values extracted from the database.
- Keyword uses declared labels found in current ability text.
- Expansion limits results to a specific set.
- Include playtesting cards reveals cards hidden from normal searches.
Choose Clear to reset every filter at once.
03 · Build
Add cards to the main deck or sideboard.
Mouse shortcut
Right-click
Right-click a search result to add one copy to the Main Deck. Hold Shift while right-clicking to add it to the Side Deck.
Drag and drop
Place it directly
Drag a search result into either deck area. The insertion marker shows where the new copy will appear.
The deck model enforces the total zone sizes and the maximum of four copies across the main deck and sideboard. If a card cannot legally be added, the deck remains unchanged.
04 · Organize
Reorder, move, remove, or sort.
- Select a batch
Hold Control on Windows or Linux, or Command on macOS, and click individual card copies in the Main Deck or Side Deck. Selected copies receive a colored border. Starting a selection in the other deck area replaces the current selection.
- Move the batch
Release Control or Command, then left-drag any selected card. Drop the batch at a new position in the same deck area or move it between the Main Deck and Side Deck. Selected cards keep their relative order.
- Move one card
Left-drag an unselected card to reorder it or move it between deck areas.
- Remove
Right-click a deck card, or drag it onto the Card Search panel, to remove one copy.
- Sort
Choose Sort Deck to replace custom ordering with the standard automatic order.
Custom order is intentional: Saving preserves the current visible order. Sorting is only performed when you choose the Sort Deck button.
05 · Save and load
Keep an editable deck or share it.
- Save
- Updates the current editable JSON file. If the deck has not been saved yet, a save dialog opens.
- Save As
- Writes the deck to a new JSON file and makes that the active save location.
- Open
- Loads either an editable JSON deck or a text decklist into the editor.
- Rename
- Changes the display name and the default filename offered for future exports.
Deck files stay wherever you choose in the system file dialog. They are separate from the application's downloaded card-data cache.
06 · Export
Prepare decks for tournaments or Tabletop Simulator.
Export Decklist
Writes the readable Speedrobo Games format with deck metadata, quantities, sets, totals, and sideboard contents.
Export Main
Creates a Tabletop Simulator PNG sheet for the main deck, including the bundled card back.
Export Sideboard
Creates a matching Tabletop Simulator PNG sheet containing the sideboard.
Install to TTS
Writes a portable saved object that references shared online face sheets and the MTD card back. Multiplayer participants can load the same assets without receiving files manually.
One-click installation: Standard Windows, macOS, and Linux TTS locations are detected automatically. If TTS uses a custom data directory, select it once and Caster's Compendium remembers it for later exports. If the shared catalog cannot be reached or does not contain a card, the application clearly reports that it used the original local-image fallback instead.
For file conversion without entering the editor, return to the main menu and use the deck-image or decklist generators.
07 · Data and appearance
Keep the card library current.
At startup, the application compares its installed release marker with the publisher-authorized hosted catalog and can prompt when either data or artwork changes. Every downloaded database is checked against its published size and SHA-256 before installation. Choose Update Card Database from the main menu whenever you want to force a complete refresh.
Choose Diagnostic Information when reporting a problem. The application displays a reviewable support summary containing the release, source revision, operating system, architecture, setup state, card count, and hosted catalog endpoint. It excludes deck contents, credentials, usernames, and exact filesystem paths, and nothing is transmitted automatically.
Settings lets the application follow the operating-system theme or use a persistent Light or Dark appearance. It also offers the unobstructed default interface and the bundled Academy Rift and Caster Duel backgrounds; both choices persist between launches.
The stable application ID remains
io.github.hybriduofa.casterdeckbuilder, so upgrading or moving to the new repository does not discard existing cached data.
