New World Order

New World Order refers towards Magic R&D's movement towards putting less complexity in the common rarity slot.

Description
R&D has always tried to make the cards as simple as possible (which is sometimes seen as "dumbing down the game"). The concept of New World Order was introduced in 2008.

One of the rules of New World Order is that common cards don't affect more than one other card while on the battlefield for simplicity of tracking the board.

New New World Order
An April Fools joke by Wizards of the Coast on April 1, 2013, introduced the concept of New New World Order. It started from a possibly believable premise and then just incrementally got crazier and crazier.
