Proteus: why a modular deckbox changes everything

One box, a thousand faces

Every TCG player knows this dilemma. You love your deckbox, but you never play just one deck. There is the aggressive Friday night deck, the casual Sunday deck for family games, the brewing project waiting for its moment: each one has its own personality, and a single box always ends up telling only one story.

That is exactly the problem the Proteus was built to solve. Its promise fits in one sentence: one box, a thousand faces. Every face of the Proteus is an interchangeable magnetic panel, and the front face welcomes sculpted 3D medallions. Switching decks? Switch faces. No tools, no fuss, done in an instant.

The multi-deck player's problem

One box per deck, really?

The classic answer is to buy one box per deck. That is perfectly legitimate, and plenty of players enjoy doing exactly that. But the approach has limits: the budget grows with your collection, the shelf fills up, and the day you take a deck apart, its box ends up orphaned.

Identity is not a detail

The other option, one generic box for everything, has the opposite problem: it says nothing about what is inside. Yet your deck has an identity. The theme you picked, the colors, the vibe: all of it deserves to show the moment your box lands on the table. A deckbox is not just storage, it is the cover of the book.

Interchangeable panels, held by real magnets

The heart of the Proteus concept is its panels. Engraved illustrations, vintage card designs, fantasy themes: the panel library keeps growing, and you can collect and combine them freely. A custom visual is also possible if you want a face that is truly yours.

N52 neodymium magnets built into the structure

For interchangeable panels to be a good idea, they have to hold. The Proteus integrates N52 neodymium magnets directly into its structure. They are what keep panels and medallions firmly in place, and what makes swapping instant, with no tools and no delicate handling.

One important clarification for anyone searching for a magnetic deckbox: at DeckSmith, the magnets serve the interchangeable panels and medallions, not the closure. The box closes with a mechanical interlocking lid, with no magnet on the closure at all. The result: no accidental opening in your bag, and no closure magnet weakening over time.

3D medallions: the relief that signs your box

On the front face, the Proteus welcomes sculpted 3D medallions: a pirate ship, a knight, a dragon. That small piece of relief changes everything. It is what gives the box its handcrafted character, the detail people notice from across the table and want to pick up.

And since panel and medallion combinations are completely free, every configuration tells its own story. A fantasy panel with a dragon medallion for the reptile deck, a vintage card panel with the pirate ship for the treasure deck: you are the one composing.

A capacity built for all your games

Beneath its many faces, the Proteus remains a serious deckbox: up to 125 standard double-sleeved cards. Enough room for a 100-card Commander deck with its tokens, a 60-card deck with a generous sideboard, or anything in between.

It is compatible with your Magic: The Gathering, Pokémon, Lorcana, One Piece and Yu-Gi-Oh! cards, and more broadly with any TCG using standard card sizes. If you play several games, that is one more argument for modularity: the same base follows you everywhere, only the faces change.
