Most often, we added one set of common cards from each of the Arabian Nights, Dark and Legends sets. Beware adding cards that allow players to mess with the libraries like Demonic Tutor and Natural Selection . Balance between colors is nice to think about, but really isn't necessary as every player has equal opportunity to draw any one color. Whenever a player is eliminated, his immediate neighbors are now considered adjacent to each other and may attack each other. This limit only applies to creature attacks and not creature special abilities, spells or other fast effects.
Players form two teams of three players, and teams sit across from each other.
Each team elects one of their players to be their Emperor. The Emperor sits between his two teammates. After determining which team goes first, play alternates by teams not players. When a team's turn comes up, the Emperor decides which player on his team gets to play that turn. However, one additional creature maneuver is allowed.
