|You may play an Action card from your hand twice.|
Cards similar to Throne Room are often called Throne Room variants.
- Playing an Action card from your hand is optional. If you do play one, you resolve it completely, then play it a second time.
- You cannot play other cards in-between (unless told to by the card, such as with Vassal or Throne Room itself).
- Playing Action cards with Throne Room is just like playing Action cards normally, except it does not use up Action plays for the turn. For example if you start a turn by playing Throne Room on Village, you would draw a card, get +2 Actions, draw another card, and get +2 Actions again, leaving you with 4 Actions.
- If you Throne Room a Throne Room, you may play an Action card twice, then may play another Action card twice; you do not play one Action card four times.
Other rules clarifications
- If you use Throne Room to play a Duration card, the Throne Room also stays in play until you discard the Duration card. This enables you to track the fact that the Duration card was played multiple times. Even if only one play of the Duration card is keeping it in play, such as using Throne Room on Gear and only setting aside cards one of the times, Throne Room stays in play with it. If the Duration card leaves play without being discarded, such as by being trashed with Bonfire, even if the Duration card is not done doing things, Throne Room is discarded the turn the Duration card leaves play.
- Throne Room plays a card twice; it does not double the effects of a card. It is possible that the card played by Throne Room does different things each time it's played.
In the first edition of Dominion, using Throne Room's ability was mandatory if Throne Room was played. Donald X. Vaccarino revised the card because that offered no provision for keeping the player honest: if a player claimed that they had no Actions in hand, and that was why they weren't activating Throne Room's ability, there was no way for their opponents to verify that this was the case.
The first-edition card text could sometimes have adverse effects in a chain of stacked Throne Rooms and draw cards: if you Throne Room a Throne Room, by the time you play the second Throne Room a second time, you might have Actions in hand that you don't want to play. Under the first-edition card text, you would be forced to play one of them (twice) anyway; in the second edition, you don't have to if you don't want to.
Throne Room is a flexible card that can be a source of +Actions, draw, or payload. Throne Room depends on having other Action cards in hand, so it's better when your deck has a high density of Action cards. Therefore, Throne Room is less good early in the game, in games where you can't get rid of your starting cards, and in games without Action payload.
Throne Room is an unusual source of +Actions. Using Throne Room to play an Action card twice nets you one more Action than you would have if you played two copies of that Action card. For example, playing two Laboratories leaves you with the same number of Actions you started with (netting +0 Actions). Throne Room playing Laboratory nets you +1 Action—if you started with 1 Action, you would end with 2. Playing two copies of a terminal Action such as Smithy costs 2 Actions; Throne Room playing a Smithy draws the same number of cards but costs only 1 Action.
Using Throne Room to play a Throne Room does not increase the number of Action cards you can double-play, but it does grant +1 net Action. For example, using Throne Room to play Throne Room to play two Laboratories grants +3 net Actions. Chaining Throne Rooms in this way is especially useful with terminal draw cards. You can start a turn by playing Throne Room playing Throne Room playing Smithy, at which point you draw 6 cards and then can duplicate one more Action card from your hand. If you can play a non-terminal Action, you can continue playing more Action cards after that. You can even continue the chain of alternating Throne Rooms and terminal Actions. Throne Room is a very efficient source of +Actions in decks with strong non-terminal cards like Laboratory. With mostly terminal Actions, Throne Room is more awkward. You generally need two Throne Rooms and a terminal draw card in your starting hand to be able to fully exploit your deck’s capabilities, and your deck is more fragile as a result. For that reason, Throne Room benefits from an alternative source of +Actions, especially one that carries over to the next turn, such as Villagers or Fishing Village.
Throne Room can duplicate the on-play effect of any Action card, so it varies in strength based on the Action cards in the kingdom. Using Throne Room on cheaper Action cards such as Merchant or Village is okay, but Throne Room is even stronger when you can use it to double-play cards such as Artisan and Laboratory that are both more expensive to gain and more impactful on play. Some cards have effects that don’t stack, e.g. draw-to-X cards such as Library) and certain Attacks (e.g. Militia), so using Throne Room on them has little to no value. Throne Room plays an Action card twice, but it doesn't put two copies in play; so cards with valuable while-in-play text such as Highway are not ideal Throne Room targets. Strong Duration cards such as Wharf can be good targets for Throne Room, but be aware that the Throne Room will stay in play with the Duration card, meaning that you can’t play the Throne Room on the next turn.
Throne Room offers a lot of flexibility, both during a single turn and throughout the game. Within a single turn, you can use early Throne Rooms to help you draw your deck, and later ones to amplify your Action payload. As the game progresses, you can adjust the number of Throne Rooms you use on drawing cards to adapt to the number of stop cards in your deck. Throne Rooms also allow you to pivot strategies more easily as the game proceeds. For instance, playing multiple Witches early in the game allows you to attack your opponents more quickly, but Witch becomes much less useful after the Curse pile empties. Using Throne Room, you can duplicate the Attack of a single Witch early on, and then choose to play Throne Room with other cards later, allowing you to avoid having to gain multiple Witches. In games with an important Action card whose pile might empty, Throne Room can allow you to play additional copies, enabling you to prioritize other objectives over ensuring you get enough copies of that card.

Secret History. My feeling was that you didn't want to buy two on turns 1 and 2, and probably didn't want to buy one on either of those turns (except with the
