Editing Lose Track rule

The '''Lose Track rule''' is a rule covering what to do with a card when it is not where an effect expects it to be. In such situations, according to the rule, the effect is unable to move the card.  This rule was officially codified in [[Dark Ages]], though [[Donald X]] had invoked it in card rulings previously.

It is possible for a card to lose track of itself, if it has an effect that tries to move itself, which is then thwarted by another effect moving it first.  For example, {{Card|Hermit}} loses track of itself when you don't buy anything in a turn, and try to trash it and gain a {{Card|Madman}}, but use {{Card|Scheme}} to top-deck Hermit before you trash it.  Because Hermit is not in play, where it expects itself to be, it loses track of itself, and does not trash itself.

* For example, if you {{Card|Procession}} a {{Card|Madman}}, Procession first puts Madman in play; then you resolve Madman, getting +2 Actions and drawing cards and returning Madman to the Madman pile; then Procession fails to put Madman into play again, because Procession expects to find Madman in play, but it is not there, it's in the Madman pile; then you resolve Madman again, only getting +2 Actions this time, since it says "if you do" before the card-drawing, and you did not actually return it to the Madman pile this time; then Procession fails to trash Madman since Procession again expects to find Madman in play and it is not there; and then you gain an Action costing {{Cost|1}} if you can.  

* For example when Procession puts Madman into play, that does not cause Procession to lose track of Madman; it is Madman moving itself that causes Procession to lose track of it.  

* {{Card|Thief}}

* {{Card|Royal Seal}}

* {{Card|Prince}}

In addition, all [[Reserve]] cards and [[One-shot]]s can be lost track of by any effect that tries to move them out of the play area, and all [[Duration]]s can be lost track of by any effect that expects them to be discarded during Clean-up.

A couple cards on this list do not yet have interactions with current cards that can invoke the Lose Track rule, but their effects could theoretically lose track of cards. For example, Thief would lose track of any [[Treasure]] it trashed with an on-trash effect similar to {{Card|Fortress|Fortress's}}.

For the most part, effects that reveal or set aside cards, then move them somewhere else, are not included here, as the act of revealing or setting aside a card does not (as of yet) trigger any sort of effect.  Likewise, effects that only trash cards, with no other movement of the card involved, are not included.  However, effects that try to set aside or trash a card ''after'' having first moved them into play or a discard pile ''are'' included.
