Enchant creature Enchanted creature gets +3/+3 and attacks each combat if able. When enchanted creature dies, this Aura deals 3 damage to that creature's controller.
原文If the enchanted creature can't attack for any reason (such as being tapped or having come under that player's control that turn), then it doesn't attack. If there's a cost associated with having it attack, the player isn't forced to pay that cost, so it doesn't have to attack in that case either.
