Most collections are invisible. They live in a binder, a deckbox and a spreadsheet nobody else can read, so the trade that would make everyone happy never happens. A public profile fixes that: one link that shows what you own, what is available, and what it costs.
What a public card profile shows
Your Herald profile displays your name, avatar, cover image and the cards you actually own — never the cards you are still looking for. Each card carries a tag: free or a price, plus an on loan tag when it is currently with someone else. Visitors get counters for total cards, cards lent and friends, and a search bar to filter your collection by card name.
Share it anywhere
The link works for anyone, logged in or not. Post it in your Discord server, drop it in a Facebook trading group, or send it to one friend before a game night. From the profile a visitor can follow you, request a card, or send you a message — and if they are not signed in yet, they are prompted to create an account first, which also connects you as friends.
Add your digital game IDs
Paper cards are only half of collecting. Your profile can also show your MTG Arena, Pokémon TCG Live and Yu-Gi-Oh! Master Duel IDs. A tap copies the ID so a friend can paste it straight into the official app and add you there too.
Why it beats a spreadsheet
A spreadsheet is a snapshot that goes stale the day you finish it. A public profile updates itself: as loans open and close, and as cards are sold, the availability tags change with them. You maintain one list and everyone else reads the current version of it.
Getting started
Create an account, set a unique username so your link is memorable, add the cards you are happy to lend or sell, then share the link. Ten minutes of setup replaces every "do you still have that card?" message you would otherwise answer one at a time.
