How we rank decks and check facts

1.Tier placements come from a named tracker, with a date

Our tier lists and meta reports do not use a house score. They copy the placement, decklist count and win rate shown by a public tracker such as One Piece TCG Meta, which says its leaders are “ranked S/A/B/C by win rate and tournament results”, or Limitless event results. Each article names the tracker and the day we read it, because these pages refresh often.

2.Card text, colors and bans come from the publisher

Card effects, colors, set codes and banlist dates are checked against the publisher's own pages, for example the official One Piece Card Game card list and Bandai's restriction notices. A card ID that resolves in our database is not enough on its own.

3.Every fact has a logged source

For every new or re-checked article we keep a source table: the fact, the URL, a short verbatim quote from that page and the date we opened it. A number or date with no matching row is removed before publication.

4.Re-checked articles show the date

When every fact in an article has been re-checked, the article shows a “Last reviewed” date and a “How we checked this” note with the number of facts traced. We do not add that date to articles that were not re-checked.
