Editing Exchange

To '''exchange''' a card is to return it to its pile ([[Supply]] or otherwise) and put another card in the discard pile in its place.  The card returned is not considered [[trash|trashed]], and the card received is not considered [[gain|gained]].  All cards that exchange themselves are [[Traveller|Travellers]], but there are two cards that can be exchanged ''into'' ({{Card|Champion}} and {{Card|Teacher}}) that are ''not'' Travellers.
== Official Rules ==
* When a player discards a Traveller from play, he may exchange it for the card indicated; he returns the card being exchanged to its pile, takes the card he is exchanging it for, and puts that card into his discard pile. 
* For example when exchanging {{Card|Peasant}} for {{Card|Soldier}}, he puts Peasant back into its pile and takes a Soldier and puts it into his discard pile.
* Exchanging is not [[trash|trashing]] or [[gain|gaining]], and so does not trigger abilities like {{Event|Travelling Fair|Travelling Fair's}}. 
* It is optional. 
* It only happens when the card is discarded from play; discarding it from hand, such as due to not playing it, will not trigger it. 
* It only happens if the card being exchanged for has any copies available; if there are no Soldiers in the pile, Peasant cannot be exchanged at that time. 
* If multiple cards do something when discarded from play, the player picks the order; for example, with no Soldiers left in the pile, a player with Peasant and Soldier in play could first exchange Soldier for {{Card|Fugitive}}, then exchange Peasant for that Soldier.
=== Other rules clarifications ===
* Exchanging must happen both ways; there must be somewhere for the discarding card to return to.  If a Traveller is bought using {{Card|Black Market}}, there is no pile to return it to and therefore it cannot be exchanged.
* However, if  {{card|Estate}} (via {{event|Inheritance}} or {{card|Band of Misfits}} is imitating the abilities of a Traveller, it can be exchanged by being returned to its own pile.

-Aside from Travellers:
-* {{Card|Changeling}} (from {{Set|Nocturne}}) can be exchanged into when gaining another card,
-* {{Card|Vampire}} and {{Card|Bat}} (also from Nocturne) exchange into each other,
-* {{Card|Trader}} allows you to exchange any card you gain for {{Card|Silver}},
-* {{Card|Hermit}} can be exchanged for a {{Card|Madman}}.

-===From Nocturne===
-* Nocturne has three cards that tell a player to "exchange" a card for another card. The card being exchanged is returned to its Supply pile, or non-Supply pile, and the card being exchanged for is taken and put into the player's discard pile. This does not count as gaining a card. The exchange only happens if both cards can be exchanged; if the pile is empty, the cards are not exchanged.
 === Other rules clarifications ===
-* Unlike gaining, exchanging can happen with a non-Supply pile without special instructions. For instance, you can use {{card|Trader}} to exchange a {{card|Horse}} for a {{card|Silver}} even though the Horse pile is not part oft the Supply.
+* Exchanging must happen both ways; there must be somewhere for the discarding card to return to.  If a Traveller is bought using {{Card|Black Market}}, there is no pile to return it to and therefore it cannot be exchanged.
-* The card being returned as part of the exchange must have a pile to go back to. Therefore cards that don't have piles of their own anywhere, such as [[Shelter]]s, [[Heirloom]]s, or [[Zombie]]s, cannot be involved in an exchange.
+* However, if  {{card|Estate}} (via {{event|Inheritance}} or {{card|Band of Misfits}} is imitating the abilities of a Traveller, it can be exchanged by being returned to its own pile.
-* The {{card|Black Market}} deck is not considered a pile; so for example if a Traveller, {{card|Vampire}}, or {{card|Hermit}} is bought using {{Card|Black Market}}, there is no pile to return it to and therefore it cannot be exchanged.
