Enchant player
Whenever a land enters the battlefield under enchanted player's control, you create a 2/2 black Zombie creature token with decayed. (It can't block. When it attacks, sacrifice it at end of combat.)
Decayed does not create any attacking requirements. You may choose not to attack with a creature that has decayed.
Decayed does not grant haste. Creatures with decayed that enter the battlefield during your turn may not attack until your next turn.
Decayed represents a static ability and a triggered ability. “Decayed” means “This creature can't block” and “When this creature attacks, sacrifice it at end of combat.”
Once a creature with decayed attacks, it will be sacrificed at end of combat, even if it no longer has decayed at that time.
The controller of Curse of the Restless Dead gets the Zombie token. This may not be the same player as the enchanted player.
