World Enchantment, R (1)
Rare (R1)
At the beginning of each player's upkeep, Storm World deals X damage to that player, where X is 4 minus the number of cards in his or her hand.
Illus. Christopher Rush

10/1/2008: This has the supertype world. This supertype is similar to legendary. The difference is that when a world permanent enters the battlefield, 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 the battlefield at the same time, they're both put into their owners' graveyards.
10/1/2009: If the player whose turn it is has four or more cards in his or her hand as Storm World's ability resolves, the ability just won't do anything that turn.
