How DiscDex works

A persistent tracker for the Brixton DGPT trading card set.

Browse the checklist

Pick a set, then a subset. View it By Player or By Parallel to find exactly the card you're after.

Mark your cards

Tag each card Sale/Trade, Want, or PC. Add a whole parallel at once with the Bulk Want panel.

Add photos and details

Record serial numbers on numbered cards, add photos from your camera or files, and choose which PC or Sale/Trade photos appear publicly.

Find a match

Your Sale/Trade cards appear in the Market. DiscDex automatically matches what you offer with members who Want it, and shows offers from your Want list.

Auction a card

Want to let the market set the price? Hit Auction on any Sale/Trade card in My Stuff to set a starting bid, increment, and end time. Other members browse Market → Auctions and place bids. The seller and winning bidder see each other's contact info when time runs out.

Message privately

Prefer a direct deal? Select one or more cards from the same member and start a private bundle conversation — either side can add their own cards too, for a real two-way trade. Nothing is saved until you send the first message.

Complete the deal

Either member can adjust bundle cards and quantities. For a one-directional bundle, the seller chooses Mark sold/traded. For a two-way trade, each side confirms — the trade completes once both have.

The terms you'll see

Sale/TradeCards you have spare. Anything you mark here is listed in the Market for other members to find.

WantCards you're chasing. Use the Bulk Want panel to add a whole parallel across every player at once.

PCPersonal Collection — keepers you're holding onto, not trading away. Drives your completion bar.

AuctionA timed listing where buyers place bids. The seller sets a starting bid, minimum increment, and end time. Highest bid when time runs out wins.

ParallelA color or foil variant of a player's card — Base, Gold, Shimmer, and so on.

Run /NPrint run: how many of that parallel were ever made. /10 means only ten exist.

Pulled / availableHow many copies members have logged versus how many of the print run are still unclaimed.

Messages and privacy

Each conversation belongs to exactly two members. A bundle can be one-directional (all cards from one member) or a genuine two-way trade (cards from both sides).
Each active conversation can contain up to 20 cards total, from either or both sides.
Opening a bundle draft does not create an inbox entry; the first sent message does.
Additions, removals, and quantity changes appear as notices in the thread.
Message dates and times display in each viewer's local timezone.
Completed conversations stay private and move from Active to Archived.

Auctions

Create an auction from the Auction button on any Sale/Trade card in My Stuff, or from Market → Auctions → + Create auction.
Set a starting bid (whole dollars), a minimum bid increment, and an end date and time.
You can auction a single card or a multi-card lot in one listing.
Bids are max bids: you enter the most you're willing to pay, and the system only shows/requires the minimum needed to keep you in the lead — your true max is never shown to anyone, including the seller.
Choose an ending style: Sudden death ends exactly at the scheduled time, or Bump timer extends the end time by a seller-chosen number of minutes whenever a bid lands within that same window.
Sellers can cancel an auction before any bids are placed.
The auction closes automatically at the end time. The highest max bid wins, at the lowest price needed to beat the next-highest bidder.
After closing, the seller sees the winner's contact info and the winner sees the seller's — connect via Whatnot or Discord to arrange the deal.
If no bids were placed, the auction ends with no winner and the cards remain on your Sale/Trade list.
Bid history shows how the price moved over time, never any bidder's private max.

After a sale or trade

For a one-directional bundle, only that bundle's seller can mark the deal complete.
For a two-way trade, either side can confirm first; the trade completes automatically once both have confirmed — nothing is removed from either collection until then.
Changing the bundle (adding, removing, or adjusting a card) clears any existing confirmations, so a two-way trade always completes on its current terms.
Completion removes exactly the bundled quantities from each side's own Sale/Trade listing and preserves any remaining copies.
If availability changes, the bundle must be corrected before completion.
Removing the final card cancels and archives the bundle.
Archived threads are read-only and can be removed separately by either participant.
Removing your archived view does not remove the other member's copy.
