This turn, you may put one of your Action cards onto your deck when you discard it from play.
Scheme is an Action card from Hinterlands. Often a very powerful card, it allows you to place back on top of your deck an Action that you played this turn. This allows for good consistency in what you can play each turn.
 Official FAQ
- When you play this, you draw a card, get +1 Action, and set up an effect to happen later in the turn; once, when you discard an Action card from play, you can put it onto your deck.
- The Action card can be Scheme itself, or any other Action card you have in play, which might have been played before or after you played Scheme.
- Scheme is cumulative; if you play two Schemes, or Throne Room a Scheme, you will be able to put up to two discarded Action cards onto your deck, and so on.
 Other Rules clarifications
- Unlike Herbalist, Scheme still has its clean-up effect even if it is no longer in play by the time you start your clean-up phase; specifically, if you play Procession on Scheme, at the start of clean-up you will be able to put two action cards from play on top of your deck, even though your Scheme has already been trashed and will not be in play itself.
- Scheme cannot top-deck a Traveller card after it has been exchanged. This is due to the Lose Track rule. Similarly, a Traveller cannot be exchanged if it is top-decked with Scheme.

Scheme is, quite simply, awesome. It’s basically like the stage crew for a rock band. It’s never standing in the limelight, and really isn’t anything special on its own, but it works to let the main players do their job. Without it the band has much less time to rock out and compose killer riffs and snort coke and … I think this analogy got away from me. Anyway, Scheme is very often worth a pick up as it lends itself very well to most engines and can be used for several very clever plays.
 The Reliable Engine
We’ve all had games where we play a Torturer only to draw 3 Villages dead. Well Scheme gives you all the benefits of a complex engine, while reducing the variance of shuffle luck, sometimes to zero. Being able to top-deck a Village/Smithy pair or a couple of Hunting Parties or whatever else it is that makes your engine go is an amazingly useful ability. Almost any engine can benefit from the addition of some Schemes.
Of course, there is a balance to strike. Every time you buy a Scheme, you aren’t buying another engine component. So in a sense, Scheme sacrifices raw power for reliability. Normally this is a good thing, but it can be taken too far. If you find yourself returning way more actions than you need to draw your deck or the Schemes themselves because you don’t have enough other things to return, you’ve likely over-invested.
Scheme is therefore best when you drop to Fishing Village.and can’t afford an engine part. It is easy to buy Scheme over Silver in most engine games, but more of a dilemma picking Scheme over
 The Non-Colliding Terminals
In Big Money type decks which only buy a few actions, Scheme can, essentially, act like a second copy of whatever flavor of terminal action you’re using. Instead of Witch/Big Money, you can simulate Witch/Witch/Big Money without the risk that the second “copy” of Witch will collide with the first. This, however, comes at a price. Whenever you draw your Scheme after your terminal, you only get to play the terminal once that reshuffle. Had the Scheme been an actual second copy of the action, you’d have gotten two plays. Over the course of a game, the double terminal deck gets more plays of the terminal action than the Scheme/terminal deck. So typically, you favor a second terminal over a Scheme.
However, when a card is more important to play early, where the chance of collision is higher, Scheme/terminal becomes the better option. Specific examples of terminals which benefit from a Scheme include Jack of all Trades, Sea Hag, and Witch.
 King's Court Abuse
King's Court is definitely the king of Scheme combos and deserves its own section. Ordinary Schemes can be used for reliability, but King's Court takes it to the next level and pushes Scheme to the point of abusiveness. The key is that a KC Scheme lets you return three cards to the top of your deck, including the KC and the Scheme itself. So technically, you don’t even need anything else: KC/KC/Scheme/Scheme/Scheme lets you start every turn with 9 cards, guaranteed. But there’s no reason not to push the envelope. Replace that third Scheme with just about anything, and you can create ridiculous games:
- Possession: KC/KC/Scheme/Scheme/Possession is a war of attrition. For every turn your opponent takes, you take three with his deck. No matter how he builds his deck, there’s not much he can do to overcome the fact that you’re playing four times as many turns as he is.
- Saboteur: Saboteur is a weak card normally, but KC/KC/Scheme/Scheme/Saboteur just obliterates your opponent’s deck far faster than they can replace it. A triple Saboteur every turn can overcome quite a bit.
- Most other attacks: KC/KC/Scheme/Scheme/Mountebank is not quite as deadly as Saboteur, but that will be of little comfort to your opponent. The problem with such attacks, though, is that the attack’s presence makes the combo a bit more difficult to set up.
- Bridge: We all know that KC/KC/Bridge/Bridge/Bridge is game over because it reduces costs by 9 and gives enough buys to buy out all the Provinces in one turn. Adding Scheme both helps set up the engine and makes it easier to set up the final death blow. This game by Mean Mr Mustard (with an Apothecary added in) is a good demonstration of how to set up a KC/Scheme engine.
- Vault: KC/KC/Scheme/Scheme/Vault leads to a 12-card discard and a guaranteed Colony every turn.
 When Not to Buy
Scheme isn’t a card you always want to buy. It’s typically a great addition to any engine and can potentially boost a Big Money deck but there are some specific times when you might want to avoid them.
The one true counter: There is one card which absolutely destroys Scheme. I am referring of course to Minion. Not only does it force you discard the nice things you top-decked, but because you are discarding your good cards, the pool you have to draw your new 4 card hand is weaker. Double Ouch.
Discard attacks: While not enough to completely forgo Scheme, discard attacks do discourage it a little. First, you don’t want to top-deck too many cards because you’ll just have to ditch them. This is in particular bad for KC/KC/Scheme/Scheme/X combos. Second, you might want to hold on to Schemes when you get hit, but the blind draw on them could mean you end up discarding a better card from hand than what you draw, which creates a bit of a dilemma. If there are discard attacks around, more than 3 Schemes is never going to help, unless you're top-decking a Moat.
Already reliable engines: As I said before, Scheme sacrifices power for reliability. But when you have an already reliable engine, and particularly when you have engine components at the same price point, you can probably forgo Schemes altogether. Something like Wharf/Fishing Village is a good example.
- King's Court
- Conspirator: Normally, the correct way to play Scheme is to top-deck your other actions. In a Scheme/Conspirator deck you want to put back 2 Schemes every turn. This guarantees that every Conspirator you play is activated, and basically lets you buy Grand Markets.
- Outpost: Scheme/Outpost needs a third card to work, but Scheme effectively neutralizes the typical drawback of Outpost by ensuring your 3 card hand has what you need in it. Menagerie and Scrying Pool are particularly outstanding candidates, though any Village/Smithy pair will do.
- Hunting Party: Hunting Parties let you set up some really fast combos that can reliably get a Province per turn, until, of course you don’t draw a Hunting Party. Then your deck with a single Gold and a ton of green can’t do much of anything. And since you really only need one Silver in your deck, there is no lost opportunity cost for picking up a scheme when you fail to hit . Scheme turns the already reliable and fast Hunting Party stack into a true juggernaut nearly immune to greening.
- Remake: Open Remake/Scheme and trim your deck super fast while still building up economy by consistently turning Estates into Silvers. Then as you transition into an engine, you already have a Scheme to help smooth it out.
- Double Tactician: These kinds of decks, when properly set up can do some amazing things and lead to extremely fast games. But if you fail to draw a Tactician to play, you can easily find yourself playing catch up. Scheme will thoughtfully place that old Tactician right back on top for you to keep it going.
- Golem: Golem/Scheme/X, once set up, will, with high probability, allow you to play the same turn every game. Replace X with a killer attack and this is a good substitute for the abusive KC combos described above. Alternatively, Golem/Scheme/Counting House is a major improvement on just Golem/Counting House. As with all cute Golem tricks, you should be wary of the fact that Golems take a long time to get and that there may be faster options.
- Scrying Pool: This card’s only weakness in an Action-heavy deck is that you might not play it every turn. Scheme solves that problem, and Scrying Pool returns the favor by drawing the Scheme back into hand.
- Monument: Want free every turn?
- Herbalist: Even the lowly Herbalist gets some use, because the Herbalist returns Treasure and the Scheme returns Actions. Pair the two up: Gold/Remodel, Alchemist/Potion. Or just return the Herbalist every turn, allowing you to return a Potion every turn, to buy up all the Vineyards.
- Trading Post: Trading Post is a uniquely nice early game trasher that benefits strongly from Scheme. Ordinarily Trading Post drops precipitously in efficacy past the first few turns of the game, but Scheme can keep it relevant through the midgame. And as you transition into another engine, the Schemes can be switched over to, say, Laboratories.
- Hermit: On turns when you don't buy anything, by choosing Scheme's effect to happen first, Hermit loses track of itself when the Madman is gained, and given that this gaining is not contingent on Hermit self-trashing, you can essentially get infinite Madmen this way.
- Prince: By Princing a Scheme, you can essentially have a flexible "Prince-anything", as the Scheme's cantrip pays for the cost of playing the Action, and can change which Action you have Princed retroactively.

Scheme had a minor functional change when Dominion was updated for its second edition. Previously, cards that were not discarded from play during Clean-up (such as Durations) could be chosen by Scheme's effect; this is no longer possible.
