About 20cards

What it does

The goal is simple: a single place where you can browse every card in the game, build a competitive 20-card deck, see what tournament players are running, and figure out which packs to open next to improve your collection.

• •Card browser — filters across every set, with legality and synergy data
• •Deck builder — tournament-derived proposals and “Make it Work” suggestions around any card you pick
• •Best decks dashboard — top archetypes ranked by tier, win rate and meta share
• •Collection tracker — personal area that tells you which meta decks you can build now and which pack is the best next pull
• •Opening hand analysis and pull-rate calculators for the data nerds

Who's behind it

A Pokémon lover. 20cards is a personal side project, built and maintained by a single person in their spare time. No company, no ads, no paid tier. If it ever grows, this page will change.

The code is written in TypeScript on top of Next.js, Supabase and Vercel. Card data comes from TCGdex and other community-maintained sources. Tournament results are aggregated from public event databases.
