Discovery: The Expandable Card Game

From BoardGameGeek:

Discovery is a 1v1, constructed, duelling card game, set in a fantasy world where four guilds battle for control over a mysterious island that's risen from the sea. Leaning heavily into thematic design, it allows players to pull from faction and archetype-specific mechanics to create their perfect decks, with a variety of win conditions to choose from. Assuming the role of a powerful Hero, each of your chosen Minions and Spells will follow your every command as you set out to complete your Quest. The Quest system is an elegant marriage of mechanics, art and short-form storytelling that streamlines resource systems and deck building, while offering strategic depth and making the genre more accessible. -description from the designer
