MAGE allows you to play magic against one or more online players or computer opponents. It includes full rules enforcement for **7210** unique cards (12178 in all). Starting with Eventide, all regular sets have all the cards implemented ([status in detail](http://ct-magefree.rhcloud.com/stats)).
There is at least one public server where you can play MAGE against other players. Apart from this, you can also host your own server to play against the AI and/or your friends.
You can visit the official MAGE forum [here](http://www.slightlymagic.net/forum/viewforum.php?f=70).
After you extract the contents of the arhive, you will find batch files to start the client/server in the corresponding directories. See the included readme files for more instructions.
