The Purple Cube enables a balanced and flavorful Magic experience for casual players and experts alike. It captures broad and deep Magic flavors and themes with the minimum cards needed for a full draft table. It has some less traditional guidelines:

• Minimize cheap blowouts and high variance cards.
• Encourage two-color decks.
• Few gold cards but ample mana fixing.
• No cheap mana denial.
• Honor the color pie.
• Limit cards that are clearly better or worse than most of the cube.
• Value versatile cards, e.g. cards with many modes or that fit into multiple spots on the mana curve.

Some more specific rules that limit the design space:

• No specific color protection.
• Two Planeswalkers for each mono color, and multi-color Planeswalkers only where they are a great choice for that guild slot.
• No "strictly better" cards.
• No functional reprints.

Also to support novice players:

• Avoid textless cards.
• Avoid cards with back faces.

This cube has been used for:

• six to eight player conventional drafts (-- and even a sanctioned draft once)
• 2v2 team sealed.
• 3-player free-for-all sealed.
• 1v1 sealed, Tenchester, and grid drafts.
