PolyTCG is a market screener for trading card games (TCGs) that provides real time price tracking for cards across eight major franchises: Pokémon, One Piece, Magic: The Gathering, Yu-Gi-Oh, Dragon Ball, Disney Lorcana, Weiss Schwarz, and Digimon. The platform covers over 320,000 individual cards and includes data on PSA grading, enabling users to monitor graded card values alongside raw market prices. A portfolio tracker and market capitalization view are also offered, allowing collectors and investors to assess the aggregate value of their holdings and the relative size of different card markets. The tool is designed for users who need up to date pricing information for buying, selling, or managing collections. Typical workflows involve searching for a specific card by name, set, or grading tier, then reviewing its historical and current price data. The portfolio tracker lets users add cards and track their combined value over time, while the market cap feature provides a broad view of the financial scale of each TCG market. The screener aggregates data from multiple sources to present a consolidated view of prices, trends, and grading information. No technical requirements beyond a standard web browser are mentioned, as the service is accessed through the website at polytcg.com. The platform does not require downloads or installations, and it supports both casual collectors and serious traders who need reliable, real time market data for decision making.
