XMage — Magic, Another Game Engine
XMage is a full rules-enforcement engine for playing Magic against other players or computer AI, online or on your own server. It supports over 32 000 unique cards and more than 91 000 reprints across official sets, plus custom sets like Star Wars.
Local server supports a special test mode for testing combos and other game situations with pre-defined conditions.
There are public servers where you can play XMage against other players. You can also host your own server to play against the AI and/or your friends — including fully offline, with no internet connection required.

Performance tweaks
The main way to increase performance or fix micro-freezes -- increase max memory usage by special java flag:
- Run launcher -> Settings -> Java tab -> Client java options text field;
- Add or change existing flag to
-Xmx3000mor another value based on your free memory stats (recommended settings: 2000m for 1080p desktop, 3000m for 4k desktop). It's useless to give 5+ GB memory; - If you play many AI games then it's recommended to change Server java options with same value too;
