About Grand Line
Grand Line (grandline.id) is a free, independent resource for the One Piece Card Game. We bring together everything a player or collector needs to follow the game in one place: a searchable card database, up-to-date market prices, the decks winning tournaments right now, and the latest product news — all free to browse, with no account required.
The site was built by a fellow One Piece Card Game fan who was tired of hopping between a dozen tabs — one for card details, another for prices, another for tournament results — just to answer simple questions like "what is this card worth?" or "what should I build next?". Grand Line is our attempt to put all of that in one clean, fast place, for players in Indonesia and around the world.
What you’ll find here
- Card Database — every set from OP-01 onward: Leaders, characters, events and promos, with artwork, traits, stats and market prices. Search and filter by colour, type, cost, rarity and more.
- Market Watch — real market prices with daily movement: the week’s biggest gainers and losers, value tiers, and a price-history chart on each card so you can see where a price has been, not just where it is today.
- Meta Decks — tournament-winning decklists with the full card breakdown and format filters, so you can study exactly what top players are running before your next locals.
- News — set announcements, product drops and lottery openings, each written up in our own words with a plain-English take on why it matters to players and collectors.
How our data works
Our prices are tracked over time and snapshotted daily, so the figures you see are built from our own ongoing record rather than a one-off lookup. The meta section is aggregated from published tournament results across Western and Japanese events and organised by set-format so you can see how archetypes rise and fall. We clean, de-duplicate and label this data ourselves — the goal is information you can actually trust at a glance.
Free site & the optional tracker
Everything described above is free. For collectors who want to go further, we also offer an optional Collection Tracker — add your cards and sealed product once and watch your portfolio’s value, profit and loss update in your own currency, with a deck-cost calculator and no ads. The tracker is a separate paid product; the public site stays free and open to everyone.
