Hex Shards of Fate is a fully digital Trading Card Game (TCG) that officially runs on Windows and OSX, but also runs well unofficially under Linux. I stream Hex several times per week on my Twitch Page and you can find archives of my streams on my YouTube Channel. I also write for HexTCG.com
If you are a Magic the Gathering player looking to get started with Hex check out my intro guide here. I also keep a list of competitive, budget standard decks updated here. You can find a general new player resource guide here.
