Editing Dominion 2019 Errata and Rules Tweaks

The '''Dominion 2019 Errata and Rules Tweaks''' were an update to existing Dominion cards and rules mainly intended to solve complex rules issues with the cards that some players had nicknamed "shapeshifters" or "emulators" but which, after the errata, became known as [[Command]] cards and [[Command variant]]s.

== Overview ==

These tweaks and errata involved modifying cards that changed their abilities at various times to instead playing the card and adding the [[Command]] type to prevent them from playing each other in loops. Certain [[One-shot|one-shots]] were changed to require the card to be trashed for the effect to trigger, as gaining their benefits repeatedly was too powerful. Cards were changed to not care about which cards of a type are yours, as you can literally lose track in certain cases. A few corresponding rules were added to facilitate these changes and simplify wordings.

==Card Errata==

===Fixed the behaviour of shapeshifting cards===
<p>
* {{Cost|5}}: {{Card|Band of Misfits}} — Plays a card from the [[Supply]], instead of becoming it. Further, it is now also a [[Command]] card and can't play Command cards (to prevent loops).</p><p>
* {{Cost|7}}: <span class="card-popup">[[Inheritance#Versions|Inheritance]]<span class="noprint">[[File:InheritanceOld4.jpg|360px|link=]]</span></span> — Inherited {{Card|Estate|Estates}} now become Actions with fixed ability and the set-aside card is played when an Estate is played, instead of the Estate gaining the types and abilities of the set-aside card. {{Card|Estate|Estates}} are Actions not based on who owns them, but rather based on whose turn it is. [[Victory]] cards are now inheritable, but not Command cards (to prevent loops).</p><p>
* {{Debt|8}}: {{Card|Overlord}} — Plays a card from the Supply, instead of becoming it. Further, it is now also a [[Command]] card and can't play Command cards (to prevent loops).</p>
* {{Artifact|Lantern}} — Now affects {{Card|Border Guard|Border Guards}} you ''play'' instead of those you ''own'' (this prevents the <span class="card-popup">[[Inheritance#Versions|prior versions of Inheritance]]<span class="noprint">[[File:InheritanceOld2.jpg|360px|link=]]</span></span> from causing issues, and works better with [[Command]] cards).

===Preserving how one-shots work===
&hellip;when {{Card|Band of Misfits}} etc. got errata
* {{Cost|4}}: {{Card|Death Cart}} — The trashing is optional, and the +{{Cost|5}} bonus is now contingent on trashing a card.
* {{Cost|5}}: {{Card|Pillage}} — All effects are now contingent on trashing the card.
* {{Cost|2}}: {{Card|Embargo}} — Adding an Embargo token is now contingent on trashing the card.

===Preventing Command card loops===
* {{Cost|6}}: {{Card|Captain}} — Now is also a Command card and no longer let's you play [[Command]] cards.

===Avoiding tracking problems===
* {{Cost|4}}: {{Card|Procession}} — It no longer let's you play [[Duration]] cards, due to a lack of tracking that came up with a [https://wiki.dominionstrategy.com/index.php/Duration#Prior_Rules rules change] .

==New Rules==

New rules were added to help facilitate the card changes and to help simplify wordings.

===Tracking for Command variants===

* Some cards, like the new Band of Misfits, can play a card that isn't put into play. 
* When you play Band of Misfits, leave it in play as long as you would have left the card it plays in play. 
** Normally that will be the same turn's Clean-up. 
** For a Band of Misfits playing a Duration card, it will be the Clean-up of the last turn the Duration card has any effects. 
** For a Band of Misfits playing a {{Card|Throne Room}} playing a Duration card, it will be the Clean-up of the turn the Duration card leaves play. 
** For a Band of Misfits playing a card that can move itself from play, like {{Card|Mining Village}}, the Mining Village can't move itself, so Band of Misfits doesn't leave play any earlier than normal. 
* If a Band of Misfits plays multiple Duration cards (e.g., you used Throne Room on it), leave it out until the Clean-up of the last turn that one of them still had effects.

===Stop-moving rule===

''Main article: [[Stop-Moving rule]]''

* An effect can move a card if it specifies where the card is coming from, or if the effect put the card where it is now. 
* If a card isn't where the effect would expect it to be, it can't move the card. 
** Played cards expect to be in play; they can't move themselves if they aren't.
** Gained cards are expected to be where they were gained to, even if this isn't the discard pile. 
* Cards in discard piles can be moved even if covered up by other cards; cards on top of a deck can't be moved once covered up.

This rule replaces the former [[Lose Track rule]].

===Look through discard when getting a card===
* When you are told to get a card from your discard pile that you choose or a card other than the top one, you can look through it to get the card. That's just implicit. You don't have to just look at the top couple of cards, you can look through the whole discard pile.

===Gain non-Supply cards when called out===
* When a card tells you to gain a non-Supply card by name, you can gain it from its pile, even though it's not in the Supply.

This allows simplifying the wording on cards that gain non-Supply cards, such as the updated {{card|Pillage}} wording.

===Costs don't go below 0===
* The cost in {{Cost}} of a card can't go below {{cost|0}}.
* The cost in {{Cost|P}} of a card can't go below 0{{Cost|P}}.
* The cost in {{Debt}} of a card can't go below {{debt|0}}.

==Trivia==
===Early discussion of exotic situations===
{{Quote|Text=[&hellip;] {{Card|Band of Misfits|oi=2}} and {{Card|Overlord|oi=1}} should be like {{Card|Necromancer|oi=1}} [&hellip;]

}}
===Reasoning===
{{Quote|Text=The reasons behind these changes are:
- It's possible for two copies of a card to have different abilities. This causes problems, the worst (extremely exotic) situation being, you play a card and don't actually know what it should do. The cards that do this are also confusing in general.

- There are cases where card interactions fail in an unintuitive way, due to it mattering if cards in a discard pile are covered up.
- Two minor rules clarify things a little and simplify texts a little, and are just coming along for the ride. [&hellip;]

===Errata to the Errata===
Other tweaks were made after feedback and discussion around the initial errata so that [[Command variant]]s can't play each other to help solve loops by adding the [[Command]] [[type]] later. This also tweaked <span class="card-popup">[[Inheritance#Versions|Inheritance]]<span class="noprint">[[File:InheritanceOld2.jpg|360px|link=]]</span></span> to target <span class="card-popup">[[Inheritance#Versions|Victory]]<span class="noprint">[[File:InheritanceOld4.jpg|360px|link=]]</span></span> cards as well.
Additionally, the look through discard rule was tweaked to not allow looking through the discard pile when explicitly getting the card on top that was just placed there to simplify card wordings.

{{Quote|Text=[&hellip;] I did make {{Card|Overlord|oi=1}} a {{Card|Overlord|Command}} [[Command|card]] for consistency, though it wasn't part of the loops; that cost very little though (you can make it matter by putting e.g. a [[Adventures tokens#Vanilla_bonus_tokens|Training token]] on {{Card|Band of Misfits|BoM}}).

===Use of Errata===
{{Quote|Text=Jay used to be against errata, unless really really necessary, because it would cause arguments when people were used to different editions. He initially resisted changing Carcassonne (the original scoring rules were worse) but when the game was a hit gave in there.

But when I finally said, let's do this thing, he was just on board. Phones have made it easier; you at least have the answer in your pocket.
