About buynder

buynder is a free tool for the two TCGs I actually play. It does three things well:

• Browse + filter every card. ~4,300 One Piece cards (including alt arts and reprints) and ~21,500 Pokemon cards with type / rarity / set / regulation filters and a compact search DSL.
• Build legal decks. 50-card OP decks with leader + 4-copy limit enforcement, 60-card Pokemon decks with variant printing picks. Multiple decks per game, save in the cloud, sync across devices.
• Track your binder + value. Per-game binders priced at TCGplayer market. Make a binder public to share a link like buynder.com/u/<you>/pokemon.

One-click TCGplayer Mass Entry

From any deck you build, the “Open Mass Entry in TCGplayer” button hands TCGplayer a pre-filled cart of every card by product ID — no name matching, no set-code guessing, no copy-pasting decklists. Same one-click flow Limitless uses.

Where the data comes from

• Card data: the official One Piece Card Game card list (English) and pokemontcg.io for Pokemon. Both scraped and normalized into our own data files.
• Card images: TCGplayer’s product CDN, keyed by product ID per variant — so Shadowless / 1st Edition / Black Dot Error etc. each show their actual photo. Old cards without a TCGplayer product fall back to pokemontcg.io.
• Prices: TCGplayer market values mirrored daily via TCGCSV. 99% coverage across both games.
• Tournament decks: scraped from Limitless TCG. OP via direct site scrape; Pokemon via Apify.
