Magic: The Gathering/5-Color Format

5-Color Format exists in slightly different variations in the online and offline Magic communities. 5-Color was initially a fan-created format, not supported by the DCI. The basic rules could be summarized as follows:

• Decks must contain a minimum of 250 cards
• Decks must have no less than 20 cards of each color
• No more than four of each non basic land card
• The game is played for ante, and ante cards, including Contract from Below, are legal

Due to the popularity of this non-sanctioned format, WotC created a similar format in the Magic online game.
