As Null Chamber enters the battlefield, you and an opponent each choose a card name other than a basic land card name. Spells with the chosen names can't be cast and lands with the chosen names can't be played.
Discovered by Femeref mages, the Null Chamber is the ultimate testing ground for the uncreative.
