In a Paladin v Warlord match, could both mages put a Fortified Position down and reveal or is it a first come-first serve proposition?
When an enchantment is revealed, if it is attached to an object or zone which already has a revealed enchantment with the same name attached to that same object or zone, the newly revealed enchantment is immediately discarded without effect. Players cannot cast an enchantment which targets a zone or object if there is either (a) a friendly hidden enchantment with the same name attached to that zone or object, or (b) a revealed enchantment with the same name (friendly or enemy) attached to that zone or object. Note that it is possible to attach a duplicate enchantment to the same zone or object as an opponent’s hidden enchantment. This would be unintentional or accidental, because you will not know that the duplication exists. Later, if the enemy hidden enchantment is revealed, you will realize that you have attached a duplicate enchantment to the same object. When this occurs, you may leave the duplicate enchantment in play as a hidden enchantment. If you later reveal that enchantment while the duplicate is still attached, you will have to destroy and discard the newer copy which you just revealed without it having any effect. When you reveal an enchantment, you only discard it without effect if there is another revealed enchantment of the same name attached to that zone or object. A hidden enchantment of the same name does not cause you to discard the newly revealed enchantment.
