Null Chamber
World Enchantment
As this enchantment enters, 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.
Rulings (3)
You choose which opponent makes the choice. Null Chamber does not target that opponent.

This has the supertype world. When a world permanent enters, any world permanents that were already on the battlefield are put into their owners' graveyards. This is a state-based action called the "world rule." The new world permanent stays on the battlefield. If two world permanents enter at the same time, they're both put into their owners' graveyards.

If you somehow manage to cast this while other spells are on the stack, those spells won't be countered.
