Gwent Cards Database helps you go through all the cards in GWENT: The Witcher Card Game.
You can browse all the available cards or search for a specific one (or subset) by using various filters.
The Gwent card data is compatible with the latest version of the game's client available.
The Gwent data below is from the Gwent closed beta version 0.8.16. You can read the full changelog between previous version (0.8.13.1) and the cards you see bellow if you click here.
A lot will change before the game gets a full release.
