Deck Compare – MTG geliştiren: Mickael Couzinet

Compare two Magic: The Gathering decklists side by side, without copying or pasting anything.

Open a deck page, click the extension, and choose the second deck: from another deck tab you already have open, from your own saved decks, or from a pasted link. You get a full visual breakdown in a new tab — cards unique to each deck shown as image grids, shared cards listed with their quantity differences highlighted, and a similarity figure.

Because it reads the decklist straight from the page you are already on, a deck hosted on one site can be compared against a deck hosted on another. Nine deck sites are supported, Moxfield, Archidekt and ManaBox among them; the extension shows the full list under its settings.

Also included:

• Cross-compare: paste several decklists and see the most-played cards across them, the average decklist, the mana curve and the top sideboard choices
• A Compare button added to each site's own toolbar, which you can switch off in the settings
• Load your public decks by username, then find them by name
• Board filters for commanders, mainboard and sideboard, with every figure recalculated for what you are looking at
• Card images and types from Scryfall
