"Reaction" is always a subtype, and the Reaction effect of a card is almost always detailed under a dividing line. As the name would suggest, Reactions have their effects triggered in response to something else happening; when its particular trigger occurs, a Reaction may be revealed by the player in order to get its effect. These triggers usually happen when the card is in its owner's hand or otherwise not visible to opponents; cards with when-gain or when-trash abilities are not considered to be Reactions. | |

+ | There are no official rules for Reaction cards in general. How to use them is detailed in the FAQ for each individual card, and in the rules descriptions of the specific mechanics on those cards. But there are official rules for certain kinds of Reactions. | ||
+ | === Reactions that can play themselves === | ||
+ | This rulebook section is from {{Set|Menagerie}}, and it applies to the following cards: | ||
+ | |||
+ | {{Set|Seaside|ed=2}}: {{Card|Pirate}} | ||
+ | |||
+ | {{Set|Prosperity|ed=2}}: {{Card|Clerk}} | ||
+ | |||
+ | {{Set|Hinterlands|ed=2}}: {{Card|Guard Dog}}, {{Card|Trail}}, {{Card|Weaver}} | ||
+ | |||
+ | {{Set|Adventures}}: {{Card|Caravan Guard}} | ||
+ | |||
+ | {{Set|Menagerie}}: {{Card|Black Cat}}, {{Card|Sheepdog}}, {{Card|Village Green}}, {{Card|Falconer}} | ||
+ | |||
+ | {{Set|Plunder}}: {{Card|Stowaway}}, {{Card|Mapmaker}} | ||
+ | |||
+ | * Playing one of these Reactions using its ability (the text below the dividing line) puts it into play, like playing it normally, but does not use up an Action. | ||
+ | * If you play a card on someone else's turn, you discard it in that turn's Clean-up, unless it is a Duration card with things left to do. | ||
+ | * If playing one of these Reactions draws you another Reaction that can be used at the same time, you can use it, and so on. For example, you might have one {{Card|Black Cat}} in hand when an opponent gains a {{Card|Province}}, play it, draw another, play it, draw another, play it. | ||
+ | * When playing one of these Reactions, you can choose to use a [[Way]] if there is one. | ||
+ | * If multiple players want to do things at the same time - such as play Reactions - the player first in turn order (starting from the player whose turn it is) goes first. This may change who wants to do what; after each thing, start again from the first player and see who has things to do. | ||
+ | * Sometimes a condition occurs that allows a Reaction to be played, and that Reaction creates a second condition that allows Reactions to be played. Resolve all Reactions for the new condition and then go back to resolving ones for the first one. For example one player gains a {{Card|Province}}, and another plays {{Card|Black Cat}}. Gaining a {{Card|Curse}} from Black Cat allows players to play {{Card|Sheepdog}}s; after resolving those you would go back to see if players had more {{Card|Black Cat}}s to play. | ||
+ | |||
+ | === When discarded === | ||
+ | This rulebook section is from {{Set|Hinterlands|ed=2|Hinterlands 2E}}, and it applies to the following cards: | ||
+ | |||
+ | {{Set|Hinterlands|ed=2}}: {{Card|Tunnel}}, {{Card|Trail}}, {{Card|Weaver}} | ||
+ | |||
+ | {{Set|Nocturne}}: {{Card|Faithful Hound}} | ||
+ | |||
+ | {{Set|Menagerie}}: {{Card|Village Green}} | ||
+ | |||
+ | * You cannot simply choose to discard these cards; something has to let you or make you discard them, to activate those abilities. The key thing to look for is a card actually telling you to "discard" cards. | ||
+ | * These abilities can happen on your own turn (such as due to {{Card|Oasis}}), or on someone else's (such as due to {{Card|Margrave}}). They do not happen in Clean-up, when you normally discard all of your played and unplayed cards. | ||
+ | * These abilities work when the card is discarded from anywhere - for example, from your hand (such as due to {{Card|Oasis}}) or from your deck (such as due to {{Card|Cartographer}}), or from being in [[Exile]] (a mat from {{Set|Menagerie|Dominion: Menagerie}}). | ||
+ | * If the card would not necessarily be revealed (such as when discarding multiple cards to {{Card|Cartographer}}), you have to reveal it to make the ability happen. | ||
+ | * These abilities are optional, even if the card was already revealed for some other reason. | ||
+ | * These abilities do not function if cards are put into your discard pile without being discarded, such as when you gain a card, or when your deck is put into your discard pile (such as with {{Card|Messenger}} from {{Set|Adventures|Dominion: Adventures}}). | ||
+ | * These abilities only happen once per time the card is discarded - you can't discard one {{Card|Tunnel}} and reveal it twice for two {{Card|Gold}}s. | ||
+ | * If you discard multiple cards at once (e.g. to {{Card|Margrave}}), they are all discarded at once, and then the abilities happen one at a time. This means for example that if you discard two {{Card|Trail}}s to a {{Card|Margrave}}, and playing the first {{Card|Trail}} causes you to shuffle, you won't be able to reveal the second {{Card|Trail}} (as it's lost in your deck at that point). | ||
+ | |||
+ | == Other rules clarifications == | ||
+ | Using the Reaction effect of a card does not necessarily involve playing the card (or putting it in the play area or carrying out its on-play effects); for instance, when you reveal a {{card|Moat}} to protect yourself from an [[Attack]], the Moat remains in your hand and does not give you +2 Cards. For Reaction cards that do cause themselves to be played as part of their Reaction effects, as listed above, their text specifically says that they may be played at that time. | ||
+ | |||
+ | Some Reaction cards' abilities instruct a player to discard them, trash them, play them, or set them aside when they are revealed for their Reaction effects. In the absence of such instructions, after being revealed, the card returns to wherever it was revealed from before the rest of its abilities are resolved. For instance, if one player plays an [[Attack]] card and another reveals a {{Card|Moat}} as a Reaction, the Moat returns to the second player's hand and may be revealed again against future Attacks, and may be played (as an [[Action]]) on their next turn. If the second player reveals a {{card|Diplomat}}, whose effect involves discarding from hand, the Diplomat returns to their hand as soon as they reveal it and may be one of the cards they discard while resolving its effect. | ||
+ | |||
+ | For the Reaction cards that are revealed from hand and remain in hand after being resolved, it is permissible to reveal the same Reaction multiple times in response to the ''same'' event; however, Reaction abilities are balanced in such a way that doing so rarely has any additional effect. | ||
+ | |||
+ | It is permissible to reveal a Reaction from one's hand in response to an event even if the Reaction was not yet in hand when the triggering event took place, provided that the ability that ''puts'' the Reaction in hand was ''also'' triggered by the same event that triggered the Reaction. For instance, if you gain a {{Card|Curse}} from another player, you may play a {{Card|Sheepdog}}, draw another {{Card|Sheepdog}}, and play it as well, and then draw a {{card|Watchtower}} and reveal it to trash the Curse. | ||
+ | |||
+ | If a player has multiple Reactions that react to the same event (e.g. if another player plays an Attack, you could react with both {{Card|Caravan Guard}} and {{Card|Diplomat}}), you can use those Reactions in any order. If multiple players have Reactions that react to the same event, players go in turn order, starting from the current player. For example, if player 1 gains a {{Card|Mill}} on their turn, then they may react with a {{Card|Sheepdog}}, player 2 may react with a {{Card|Black Cat}}, and player 3 may react with a {{Card|Falconer}}. In this case, player 1 goes first. | ||
+ | |||
+ | If another player uses a Reaction, any previous players in turn order get another chance to react (starting with the current player). However, once all players have declined to use a Reaction, no one may use Reactions anymore. Note that this only applies to Reactions and not other abilities. So if player 1 plays an Attack, then player 3 can reveal a {{Card|Moat}}, and that would give player 2 a second chance to reveal their own {{Card|Moat}}. But if player 1 didn't trash an {{Card|Urchin}} for a {{Card|Mercenary}}, they don't get a second chance to do so. | ||
+ | |||
+ | == Strategy == | ||
+ | Many Reaction cards may be revealed in response to an opponent playing an Attack card, and offer some type of defense against some or all Attack cards. Several Reactions that react to events other than Attacks may also offer some protection from Attacks; for instance, {{Card|Watchtower|Watchtower's}} Reaction ability protects a player against [[junking attack|junking attacks]], and its Action ability protects a player against [[handsize attack|handsize attacks]]. Since the first Reaction card that many players encounter is Moat, it is a common misconception among new players that ''all'' Reactions are revealed in response to Attacks being played, or even that all Reactions offer Moat-like cancellation of Attack effects. However, not all Reactions offer any protection against or interaction with Attacks at all (e.g., {{Card|Fool's Gold}}), and not all cards that protect a player against attacks are Reactions (e.g., {{Card|Lighthouse}}). | ||

+ | It would be that you put {{Card|Market Square}} into play when using it to get a {{Card|Gold}}, not that you play it. Well I would get to try the cards and see what worked best, but that's the idea. By putting the card into play, you use it up, and this is key for some effects, it stops loops.

Yeah, they should have all been like {{Card|Sheepdog}}. {{Card|Sheepdog}} is perfect, and exactly what they should be like. But that should be codified into reactions to save even more space, and make them simpler. And then I could have had more reactions. And the way, the whole reason reactions… Reactions were originally like that. So {{Card|Sheepdog}} says when you gain a card, you may play this. That’s the kind of reaction it is. So, it’s just that you can play it at an unusual time. But you can also just play it normally. It’s an action-reaction. And originally reactions were like that, but {{Card|Moat}} wanted to be used multiple times in a round, for multiplayer. And so it ended up being “you reveal it to do the reaction”. And then that ended up being how reactions worked. And it’s not… It’s very poor, because while {{Card|Moat}} is a good card to work that way, most things you might want to do don’t work so well that way. | ||
+ | |||
+ | |||
+ | And so, {{Card|Horse Traders}} tries to be, has this giant wall of tiny text in order to get the kind of ability I want, where it’s just “if somebody attacked I can draw card.” And instead, it should have been something like, when you play it and it says, “if anyone attacked since your last turn, +1 card”. That would have been fine. But it’s all this wording, and really you want it to be that just reactions are cards you can play at unusual times. You play them then. It does what it says when you play it. | ||

Reaction is a card type. Reaction cards have blue frames, and appear in most expansions. "Reaction" is always a subtype, and the Reaction effect of a card is almost always detailed under a dividing line. As the name would suggest, Reactions have their effects triggered in response to something else happening; when its particular trigger occurs, a Reaction may be revealed by the player in order to get its effect. These triggers usually happen when the card is in its owner's hand or otherwise not visible to opponents; cards with when-gain or when-trash abilities are not considered to be Reactions.
Reaction effects can occur anytime their trigger happens, not just during your own turn.

[edit] Rules
There are no official rules for Reaction cards in general. How to use them is detailed in the FAQ for each individual card, and in the rules descriptions of the specific mechanics on those cards. But there are official rules for certain kinds of Reactions.
[edit] Reactions that can play themselves
This rulebook section is from Menagerie, and it applies to the following cards:
Seaside (Second Edition): Pirate
Prosperity (Second Edition): Clerk
Hinterlands (Second Edition): Guard Dog, Trail, Weaver
Menagerie: Black Cat, Sheepdog, Village Green, Falconer
- Playing one of these Reactions using its ability (the text below the dividing line) puts it into play, like playing it normally, but does not use up an Action.
- If you play a card on someone else's turn, you discard it in that turn's Clean-up, unless it is a Duration card with things left to do.
- If playing one of these Reactions draws you another Reaction that can be used at the same time, you can use it, and so on. For example, you might have one Black Cat in hand when an opponent gains a Province, play it, draw another, play it, draw another, play it.
- When playing one of these Reactions, you can choose to use a Way if there is one.
- If multiple players want to do things at the same time - such as play Reactions - the player first in turn order (starting from the player whose turn it is) goes first. This may change who wants to do what; after each thing, start again from the first player and see who has things to do.
- Sometimes a condition occurs that allows a Reaction to be played, and that Reaction creates a second condition that allows Reactions to be played. Resolve all Reactions for the new condition and then go back to resolving ones for the first one. For example one player gains a Province, and another plays Black Cat. Gaining a Curse from Black Cat allows players to play Sheepdogs; after resolving those you would go back to see if players had more Black Cats to play.
[edit] When discarded
This rulebook section is from Hinterlands 2E, and it applies to the following cards:
Hinterlands (Second Edition): Tunnel, Trail, Weaver
- You cannot simply choose to discard these cards; something has to let you or make you discard them, to activate those abilities. The key thing to look for is a card actually telling you to "discard" cards.
- These abilities can happen on your own turn (such as due to Oasis), or on someone else's (such as due to Margrave). They do not happen in Clean-up, when you normally discard all of your played and unplayed cards.
- These abilities work when the card is discarded from anywhere - for example, from your hand (such as due to Oasis) or from your deck (such as due to Cartographer), or from being in Exile (a mat from Dominion: Menagerie).
- If the card would not necessarily be revealed (such as when discarding multiple cards to Cartographer), you have to reveal it to make the ability happen.
- These abilities are optional, even if the card was already revealed for some other reason.
- These abilities do not function if cards are put into your discard pile without being discarded, such as when you gain a card, or when your deck is put into your discard pile (such as with Messenger from Dominion: Adventures).
- These abilities only happen once per time the card is discarded - you can't discard one Tunnel and reveal it twice for two Golds.
- If you discard multiple cards at once (e.g. to Margrave), they are all discarded at once, and then the abilities happen one at a time. This means for example that if you discard two Trails to a Margrave, and playing the first Trail causes you to shuffle, you won't be able to reveal the second Trail (as it's lost in your deck at that point).
[edit] Other rules clarifications
Using the Reaction effect of a card does not necessarily involve playing the card (or putting it in the play area or carrying out its on-play effects); for instance, when you reveal a Moat to protect yourself from an Attack, the Moat remains in your hand and does not give you +2 Cards. For Reaction cards that do cause themselves to be played as part of their Reaction effects, as listed above, their text specifically says that they may be played at that time.
Some Reaction cards' abilities instruct a player to discard them, trash them, play them, or set them aside when they are revealed for their Reaction effects. In the absence of such instructions, after being revealed, the card returns to wherever it was revealed from before the rest of its abilities are resolved. For instance, if one player plays an Attack card and another reveals a Moat as a Reaction, the Moat returns to the second player's hand and may be revealed again against future Attacks, and may be played (as an Action) on their next turn. If the second player reveals a Diplomat, whose effect involves discarding from hand, the Diplomat returns to their hand as soon as they reveal it and may be one of the cards they discard while resolving its effect.
For the Reaction cards that are revealed from hand and remain in hand after being resolved, it is permissible to reveal the same Reaction multiple times in response to the same event; however, Reaction abilities are balanced in such a way that doing so rarely has any additional effect.
It is permissible to reveal a Reaction from one's hand in response to an event even if the Reaction was not yet in hand when the triggering event took place, provided that the ability that puts the Reaction in hand was also triggered by the same event that triggered the Reaction. For instance, if you gain a Curse from another player, you may play a Sheepdog, draw another Sheepdog, and play it as well, and then draw a Watchtower and reveal it to trash the Curse.
If a player has multiple Reactions that react to the same event (e.g. if another player plays an Attack, you could react with both Caravan Guard and Diplomat), you can use those Reactions in any order. If multiple players have Reactions that react to the same event, players go in turn order, starting from the current player. For example, if player 1 gains a Mill on their turn, then they may react with a Sheepdog, player 2 may react with a Black Cat, and player 3 may react with a Falconer. In this case, player 1 goes first.
If another player uses a Reaction, any previous players in turn order get another chance to react (starting with the current player). However, once all players have declined to use a Reaction, no one may use Reactions anymore. Note that this only applies to Reactions and not other abilities. So if player 1 plays an Attack, then player 3 can reveal a Moat, and that would give player 2 a second chance to reveal their own Moat. But if player 1 didn't trash an Urchin for a Mercenary, they don't get a second chance to do so.
[edit] Strategy
Many Reaction cards may be revealed in response to an opponent playing an Attack card, and offer some type of defense against some or all Attack cards. Several Reactions that react to events other than Attacks may also offer some protection from Attacks; for instance, Watchtower's Reaction ability protects a player against junking attacks, and its Action ability protects a player against handsize attacks. Since the first Reaction card that many players encounter is Moat, it is a common misconception among new players that all Reactions are revealed in response to Attacks being played, or even that all Reactions offer Moat-like cancellation of Attack effects. However, not all Reactions offer any protection against or interaction with Attacks at all (e.g., Fool's Gold), and not all cards that protect a player against attacks are Reactions (e.g., Lighthouse).
