Dominion 2019 Errata and Rules Tweaks
The Dominion 2019 Errata and Rules Tweaks were an update to existing Dominion cards and rules to mainly solve complex rules issues with early Emulators.
These tweaks and errata involved modifying cards that changed their abilities at various times to instead playing the card to emulate and adding the Command type to prevent them from playing each other in loops. Certain one-shots were changed to require the card to be trashed for the effect to trigger, as repeated emulation 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
 Emulators with New Errata
- Band of Misfits — Plays a card from the Supply, instead of becoming it. Now is also a Command card and can't play Command cards (to prevent loops). :
- Captain — Now is also a Command card and can't play Command cards (to prevent loops). :
- Inheritance — 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. 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). :
- Overlord — Plays a card from the Supply, instead of becoming it. Now is also a Command card and can't play Command cards (to prevent loops). :
 One-shots with New Errata
- Embargo — Adding an Embargo token is now contingent on trashing the card. :
- Death Cart — The trashing is optional, and the + bonus is now contingent on trashing a card. :
- Pillage — All effects are now contingent on trashing the card. :
 Other New Errata
- Procession — It can no longer play Durations (to avoid tracking issues). :
- Lantern — Changes Border Guards you play instead of those you own (this prevents the prior versions of Inheritance from causing issues, and works better with the newer emulators).
 New Rules
New rules were added to help facilitate the card changes and to help simplify wordings.
 Tracking for Emulators
- 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 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 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, or has moved away from there and then back, 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 Pillage wording.
 Costs don't go below 0
- The cost in of a card can't go below .
- The cost in of a card can't go below 0 .
- The cost in of a card can't go below .
 Errata to the Errata
Other tweaks were made after feedback and discussion around the initial errata so that Emulators can't play each other to help solve loops by adding the Command type later. This also tweaked Inheritance to target Victory 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.
