XMage is a client-server application for playing Magic: The Gathering (MTG). XMage’s development was started in early 2010. Since then, it has seen 182 releases, attracted an army of contributors, and it’s still being actively developed even now. All that makes it a good reason for us to contribute to its development too! So, today the PVS-Studio unicorn is going to check the code base of XMage and maybe even get into a fight with some entities.
