Manage Collection & Decks

The core of MTG Collection Lens is your database. Here's how to keep it synchronized and accurate.

Import Collection

To start highlighting cards, you need to upload your inventory. We support CSV exports from the most popular collection managers.

1. Use "Open Moxfield Collection" or "Archidekt Collection"

Inside the extension popup, use the Open Moxfield Collection or Open Archidekt Collection button. It will take you directly to the correct page and we'll highlight exactly where to click to get your file.

1b. Download Inventory from Deckbox, ManaBox or MythicHub

If you track your collection via Deckbox, Ma naBox or MythicHub, you can simply download your inventory CSV and upload it directly.

2. Upload to a named Binder

Set a binder name (e.g. "Trade Binder") and drag and drop the file into the extension's upload zone. Multiple binders allow you to keep your collection organized and tracked separately.

Decks Management

Adding your decks allows the extension to show you which cards are "Available" versus "In Use".

One-Click Sync (Recommended)

The easiest way to track your decks is the Import All My Moxfield Decks or Import All My Archidekt Decks button. Note that you must be logged into the respective service in your browser for this to work.

Manual Deck Insertion

Not on Moxfield? No problem. Use the New Deck button and paste your list. We support standard text formats (e.g., 1 Sol Ring).

Bulk Import from Folder/User

Use the Import Folder Link... button to import dozens of decks at once. Simply paste a link to a Moxfield User profile or a specific Archidekt folder, and the extension will scan and import every public deck found.

The [[Proxy]] Tag

Want to track playtest cards? Add [[Proxy]] to any line in your decklist. The extension will highlight these in Orange instead of Green, so you always know what's real and what's a proxy.

Category Management

New Categories: Create custom categories like "Standard," "Trade Binder," or "Playtest" using the New Category button.
Drag-and-Drop: Reorder your categories globally by dragging their headers, or sort decks within/between categories with ease.
Auto-Categorization: Moxfield imports automatically sort decks into "Commander Decks" if a commander is detected.
Flexible Deletion: Deleting a custom category is safe—any decks inside are automatically moved to "Others."

Settings

Customize the behavior and appearance of the extension to fit your workflow.

Count Decks as Collection: Toggle whether your decklists contribute to your total owned count.
Mark Unavailable: When enabled, cards needed for a list but not in your collection are marked as such.
Color Customization: Pick custom highlight colors for standard cards and proxies to match your preference.
Site Toggles: Choose exactly where the extension should activate. Support for EDHREC, Scryfall, MTGGoldfish, MTGDecks, and MTGTop8 can be toggled individually.
Show Binder Info: Display information about your specific binders on the respective websites.
Database Management: Export your entire state (collection, decks, and settings) as a JSON file for backup or multi-device sync.
