You already own more decks
than you think.
DeckBorn reads your collection once and weighs it against thousands of decklists. You get an ordered list of what you can build tonight, and the exact cards standing between you and everything else.
- Import · any CSV with a Scryfall ID
- Decks · indexed every few hours
- Card data & prices · Scryfall
One file. Then never again.
Export a CSV from wherever your collection already lives and drop it in. Every row is resolved to a real printing and indexed once — from then on the whole site knows what you own.
- A CSV you already have, not a form to fill in
- Rows resolved to real printings, not name strings
- Your collection is stored under your account and never shared
The CSV drop, the import line running, and the first card count landing on an empty account.
Every decklist, weighed against your shelf.
Thousands of decklists scored against what you own, ordered by how close you are. Narrow by format, set a floor on the match percentage, or sort by what other people liked.
- A match percentage before you open anything
- Filter by format and by minimum match
- Every filter is in the URL — shareable, and the back button works
The match list re-ordering as the format filter changes and the minimum match slider moves.
The exact cards in the way.
Open a deck and the breakdown splits it in two: what you already have, and what is missing — with a current price against each missing line, so the cost of finishing it is a number rather than a feeling.
- Owned and missing, card by card
- A price against each missing line
- Basic lands called out separately, so they do not skew the gap
A deck page scrolling from the match percentage down through the missing list, prices totting up.
Build from what you own. Watch what it's worth.
Start a worksheet blank, from a decklist you paste, or from a URL. Your collection page keeps the value history behind it, and names the cards that moved.
- Three ways to start a deck: blank, pasted, or imported
- Search the full card index while you build
- Collection value over time, and the movers behind it
The builder filling a curve from card search, then the collection value chart drawn across thirty days.
