Cornered Market

Enchantment, 2W (3)
Players can't cast spells with the same name as a nontoken permanent.
Players can't play nonbasic lands with the same name as a nontoken permanent.¹
Don't step on the livelihood of other vendors, or they may step on you. -Mercadian saying.
Illus. Edward P. Beard, Jr.

Gatherer Card Rulings [Nov 2009]

• 10/4/2004: Cornered Market does not prevent effects which put a card onto the battlefield. It only stops people from casting.
• 10/4/2004: This card only looks at permanents, not spells on the stack. So it is possible to cast two instances of a spell onto the stack.
