## What it is
XMage is a free, open-source, full rules-enforcement engine for playing Magic: The Gathering online against other players or AI opponents, supporting over 32,000 unique cards and many formats like Commander and drafts. It ships as a Java client-server application with a deck editor, tournaments, and a Glicko rating system, and can be self-hosted or played offline.

## Use cases
- play magic the gathering online free
- play mtg against computer ai opponents
- host my own magic the gathering server
- play commander multiplayer online with friends
- test card combos with predefined game situations
- build and import mtg decks
- play magic offline without internet
- join free mtg tournaments and drafts
