The Martian Gathering brings two armies of Icehouse pyramids with different powers to the battlefield, where their commanders apply their leadership and magical skills through Magic cards to achieve victory. You need Icehouse pieces for the five colours of Magic: The Gathering plus a clear set if you want to use colourless spells. The game plays fine with the basic set and fewer card colors. Each player also needs 20 Magic cards which fit their anticipated army. Knowledge of the Magic: the Gathering rules is assumed. Rules Link
