CardWeaver

From BoardGameGeek:

CardWeaver is a one-versus-all deckbuilding card game based on the world of The Shared Dream. Up to 3 players team up against another player and whichever team survives wins. Each player purchases cards from a market (called the Dreamscape) that is set by the character they have chosen. This gives each character its own capabilities, playstyle and strategies, while emphasizing teamwork since no one character can fill every role in the team. -description from the publisher
