Now on the wiki! http://wiki.dominionstrategy.com/index.php/Masterpiece#Strategy_Article

There's a lot to be said for Silver.  For a while, Silver was used as a baseline for moderate-price cards, although the "Silver test" is regarded more with scorn than anything nowadays.  Silver is reliable - it adds literal buying power to your deck.  Over the expansions, we've seen cards that devalue and revalue Silver - from the highs of the base set where Big Money reigned supreme, to the lows of Prosperity where Silver just couldn't cut it anymore, and back up again with Hinterlands and Dark Ages, the latter of which gave us Feodum, finally giving Silver its place in the sun - no longer just the means to gaining Victory points, but potentially the actual Victory points itself.  Trader, Bureaucrat, Talisman - all great Feodum enablers, but all of them pale in comparison to Masterpiece.

Well, what is it?

Masterpiece is quite simple - perhaps the only simpler kingdom Treasure is Cache.  When you buy Masterpiece, the number of coins you overpay is turned into the same number of Silvers for you to gain.  Once it's in your deck, it's just an expensive Copper.  Unlike other overpay cards which are at least sometimes worth buying for their nominal cost, Masterpiece is an idiotic purchase to make at its stated price.  $3 for a Copper?  You must be out of your mind.  Well, how about $4?  Now you're getting a Silver with your Copper, but often you'd be happy buying Silver at $4 anyway, so what do you need this extra junk for?  $5 - now we're getting somewhere.  Two Silvers for less than the price of two, and all I need to do is take a Copper with it?  Not a bad deal.  At $6 and beyond you are now really starting to get your money's worth.  But how often do you want an enormous pile of Silvers?  In Big Money strategies, buying Masterpiece for $6 or more can sometimes be superior to Gold, but most engines will sputter and die with that many non-drawing cards in your deck.

So how do I use it?

For BM-Terminal draw, focus on getting one big Masterpiece buy.  After getting your Council Room or DoubleJack, purchase a Gold on your first $6, and then buy one big pile of Silvers.  You want the benefit of the Silvers to overpower the single "Copper" you're buying as much as possible, so aim high!  Then just reel in the Provinces.

Other than BM kingdoms (or just plain crappy ones), Masterpiece is best in kingdoms that want lots and lots of Silver - in other words, alt-VP kingdoms.  Gardens directly benefits, and Silk Road and Duke are much helped by the influx of coin.  But Feodum is the superstar here.  Paying $6 for a Masterpiece immediately raises the point value of each of your Feoda by 1.  If you take every Masterpiece (at a good price), and take, say, 36 of the 40 Silvers, you're looking at 12 point Feoda.  That's DOUBLE Province, and more than Colony.  With all 8 Feoda, you're looking at a maximum of 96 points.  Obviously, only an idiot (or a bot) would let you take the whole Feodum and Silver piles, but even with half of each, that's still 4 6-point Feoda for a total of 24 points.  Not to mention that 20 Silvers in your deck will help buying other Victory cards.  A note for this strategy - it's far more important to win the Silver split than the Feodum split - better to ratchet up the Feoda you have (while increasing your buying power) than to crack down hard on the pile.

Outside of alt-VP strategies and Big Money, you probably won't want to buy more than one Masterpiece.  Just picking up one for $6-$9 will dramatically improve your deck.  And the Masterpiece itself then makes an excellent target for Trash-for-Benefit cards, such as Salvager, Apprentice, Bishop, Mine, Counterfeit, Remodel...  The Silvers gained with it can also make good targets for these cards.  Or you can just pass the Masterpiece to your opponent with Ambassador or Masquerade - the only useful part of the card is its on-buy overpay, which your opponent will not be able to get here.  These two cards are also great for trashing away the Estates and Coppers in your starting deck, and along with Chapel, they are great companions to Masterpiece - trash away everything except your pile of Silvers, and you'll be getting Provinces quite quickly.

Because the Masterpiece itself is just a Copper, if you're going for a TfB or Big Money strategy, you'll want to either find some way to quickly get rid of the Masterpiece, or to never gain it all together.  Trader it into one more Silver, or Watchtower it into the trash.  Watchtower can then dump the whole pile of Silvers on top of your deck, possibly ensuring a Province buy.

But if you're going for an engine, you may want to ignore Masterpiece entirely, particularly on boards where you're ignoring Silver anyway, such as Colony/Platinum boards, where Silver can actually be just as bad as Copper.  Why would you overpay for a Masterpiece when you can get one Platinum that won't clog your Goons engine?

My opponent just bough a huge pile of Silvers with Masterpiece!  What do I do?

There are a couple options.  You could try to outrace them with a sleek engine that isn't clogged with Silvers.  You could wait them out with a VP token or Gardens strategy.  You could buy your own Masterpiece!  But there are direct ways to combat the pile of Silvers.  Discard Attacks are the obvious route, as 3-card hands aren't very good at buying Provinces in decks with mainly Silver.  General discarding Attacks like Militia or Margrave fill this role, but Treasure specific Attacks are also useful - Cutpurse moreso at the beginning, to prevent your opponent from getting the Masterpiece in the first place, whereas Taxman will be useful the whole game.  Even Thief is useful against Masterpiece deck, as you are now much more likely to hit a "good" Treasure than to whiff on Copper.  And, as usual, Cursers and Looters will make it much harder for your opponent to line up enough Silvers.

Conclusion

So Masterpiece will work in some decks, but not in others.  Regardless, there's an elegance to how the card works.  There's even a certain elegance to the theme of this card - you get out of it exactly what you put into it, which is the case for actual works of art.  The more you put into it, the more you reap.

Synergies:
-Feodum, Gardens
-Other Alt-VP (except perhaps Fairgrounds)
-Any BM strategy
-Trash-for-benefit cards
-Heavy trashing (Chapel, Ambassador, etc)
-Watchtower/Trader

Anti-synergies:
-Engines
-Colony/Platinum

In my experience, Gold is better than $6 Masterpiece for BM strategies. The reason is that with Masterpiece, you'll get lots of mediocre hands, and with Gold, you'll get one better hand and another hand that's not as good. Getting that better hand is especially important in games with Masterpiece, since every extra dollar is an extra Silver and the more Silver you can get with a single Masterpiece, the less Masterpieces you will need in your deck.

Also, I think you should mention that Masterpiece is mostly just a nice addition to decks like DoubleJack, but absolutely nuts with terminal draw BM, especially Council Room. Masterpiece benefits from the huge handsize and the +buy comes in handy a lot of time too, and additionally, unless your opponent goes for Masterpiece himself, any Council Rooms he plays will help you much more than the Council Rooms you play help him.

For the same reason, any discard attack on the board pretty much invalidates Province strategies featuring Masterpiece because a $6 hand doesn't buy a Province.

So you're saying you would buy gold over masterpiece in a terminal draw BM because then you can get better masterpieces?    I feel like in terminal draw BM I would want silver over gold.  your gold coming up in a hand with all your VP kinda sucks, but having 3 silvers spread out will either give you the extra 1-2 you need for the province, or still make a good masterpiece buy.  But your discard attacks portion is valid.  I would still think masterpiece would be viable though because if you're doing terminal draw and have tons of silver, you can probably get to 6-8 by playing your smithy or margrave or whatever.

Yeah. I think you're underestimating how much Masterpiece itself hurts your deck. You want to minimize the number of Masterpiece buys and maximize the number of Silver gains, therefore, you want as big Masterpiece overpays as possible. For $6, Gold is $3 of buying power in a single card, Masterpiece is $7 of buying power spread over four cards and while they both help you in reaching $8 for the Province buy, Gold obviously helps you more in getting a big Masterpiece buy and the big Masterpiece buy is what you want because that enables early greening. For example, in this game, my turn 7 Masterpiece buy with overpay with 12 was lucky, but it was all thanks to the fact that I had two Golds in my deck instead of more Silvers and Masterpieces and after that, I could just buy some extra terminals to make up for the increased deck size and bought 6 Provinces and two Duchies on turns 10-14.

Fair enough.  I forgot about the masterpiece itself.  Although, nowadays, sets without some form of trashing are less common.  But with BM you can't really afford trashing.  So I guess I agree with you.  Sorry for misunderstanding.

[Warfreak2]

Just wanted to offer a few sample games:
Chapel/Masterpiece getting 4 Provinces in 13 turns, 6 Provinces and 2 Duchies in 17 turns - after only two big Masterpieces, the deck is almost all Silver, ready for Provinces almost every turn.
Masterpiece/Gardens creating a big deck which is resilient to greening and opponent's junking, and 8-point Gardens. (In this game, I think the lack of +buy really helps the Gardens player to outrace the engine).
Masterpiece/Feodum showing that the Feodum split is much less important than the Silver split - my early Feodum buys are even probably mistakes.

[AHoppy]

Here's another feodum-masterpiece game that shows that the silver split and bigger masterpiece buys are more important than the feodum split

[Schneau]

Has anyone done BM-terminal draw simulations with and without Masterpiece? I feel like this would be informative as to whether Masterpiece is worthwhile, especially at $5 and $6 in this type of deck.

The article indicates that Masterpiece is good with T4B. But, it seems to me that flooding your deck with Silvers is going to make it hard to connect your T4B cards with your Masterpieces, unless you also have heavy trashing of your starting cards. I'm guessing this is a nombo more often than not.

[Warfreak2]

Depends how many Silvers you take, and what you use them for. For example, you could have a draw engine which buys a Masterpiece every turn, trashes all the Silvers with Counterfeit, and Remodels the Masterpiece into another Counterfeit or engine component. This way you could double-Province while still building.

Another example would be using Forge to turn Masterpiece and two Silvers into Platinum, or add an Estate to get a Colony.

An $n Masterpiece adds $(3n-6) of card value to your deck, which can be efficient for TfB if you don't keep those cards in your deck. If the Masterpieces are too big then it's hard to churn through all of the cards, but $5 or $6 could be a sweet spot for TfB, if there's an engine to support it.

[DG]

You can use masterpieces with a partial defense (like a moat, masquerade, trader) against junking attacks. By flooding your deck with silver the junk has little or no impact. It's not possible all the time but it is a situation where you would buy a number of masterpieces.

Royal seals and watchtowers provide an instant reward for buying a masterpiece.

[Warfreak2]

Watchtower/Masterpiece sounds like a combo, you can trash the Masterpieces while getting all the Silver in your next hand, and the Watchtowers defend against discard attacks.

[SirPeebles]

I was about to say it doesn't combo with JoaT, but then I remembered you could use it top-deck the Silver.  But...  then you have a spot in your hand taken up by Watchtower that could have been a Silver in the first place.  So.  Nombo with JoaT.

On a related note, I'm going to be updating the article.

Masterpiece-Dukeany slog is really strong.

[Markov Chain]

Other combos: Mine or Taxman.  If you mine or tax a Masterpiece, it turns into gold, negating its disadvantage.  Also, the silvers which come with Masterpiece are good mining targets if you don't have the Masterpiece itself, and even better taxing targets if your opponents don't have Masterpiece themselves.

Let's say you're playing strictly Smithy-BM, and it's the mid-game phase (i.e. you got 2 Smithys but it's not Duchy time yet). For $5, do you get Silver or Masterpiece?

Tactician Masterpiece is a great big money strategy, too. 

[shark_bait]

This card is under-rated and I believe that this article could be expanded upon/improved.  Here are my main considerations.  I'm just going to go sequentially through the article and pose my arguments.

Well What is it

This section is fine as is.  The last sentence is a bit out of place.

In Big Money strategies, buying Masterpiece for $6 or more can sometimes be superior to Gold, but most engines will sputter and die with that many non-drawing cards in your deck.

In most cases buying a Masterpiece at $6 or more is superior than Gold.  More on this later.  Masterpiece is not meant to be an Engine card.  It's use in engines is mostly irrelevant.  In engines, the raw power of Gold in a single card is much more useful than the influx of Silver.

So How Do I Use It

The first paragraph is not emphasized enough.  That first Gold is extremely helpful.  Subsequent $6 should most often be Masterpiece buys.  For Masterpiece to truly shine you need more than just one Masterpiece buy.  You are looking to absolutely flood your deck with Silver allowing you to do a few things extremely well.

1.)  Green earlier
2.)  Prevent choking

What does this mean in the context of deck construction?  Let's take a theoretical example.  You have 18 cards in deck including a Smithy meaning you get 3 hands before your next reshuffle.  In your deck you hand 7x Copper, 3x Estate, 5xSilver, 1x Gold, 1x Masterpiece, 1x Smithy.  This is a total of $21 gold over 18 cards giving you a density of $1.16/Card (Province buying is $1.6/Card).  With your $21 over 3 hands you buy 3 Masterpieces overpaying for each one resulting in gaining 3 Masterpieces and 12 Silver.  Let's recalculate average money density.  You have $48 money in 33 Cards giving you $1.45/Card.  Imagine you had bought 3 Gold instead of Masterpiece you would be at $30/21 Cards = $1.43/Card. 

So by going Masterpiece over Gold you are keeping your average money density about the same but your buffer capacity (I teach orgo lab and just graded a ton of reports with a phosphate buffer system, had to put in chemistry blurb) is much better.  You deck size is 33 as opposed to 21.  This means that as you are less prone to choking on green.  You can green earlier on Duchies and use the extra VP to outlast you Gold gaining opponent in the long run.

So back to constructing you deck.  The above was an ideal hypothetical example.  In practice I have found it to be most useful to flood the deck when you deck is in peak condition.  This usually happens after the 2nd reshuffle.  So you should look for these Masterpiece buys starting at Turn 5 and onward.  After you have gotten about 2 or 3 Masterpiece buys you are ready for greening.  There is wiggle room on deciding whether $8 should be Province or Masterpiece + 5x Silver.  My advice for this is to ask yourself the following:  Will you make it completely through your deck again?  If yes, go for the Silver, if no, go for the Province.  When your deck is medium sized.  You can get Duchies on $5.  If you're going through your deck again (think of the amount of VP left) you probably want $6-7 to be Masterpiece.

On the topic of TfB and Masterpiece.  I would say that this is a nombo.  Masterpiece floods your deck with Silver making it unlikely that said TfB will hit that Masterpiece which is the ideal Target.  Silver is a mediocre card for almost all TfB that could conceivably be used.

Masterpiece also excels in slogs. 

Cursers and Looters will make it much harder for your opponent to line up enough Silvers

I disagree with this.  Cursers and Looters are cause to go for Masterpiece.  They serve to stall your deck by increasing your deck size and thus lowering your average money density.  The presence of Masterpiece allows you to create a buffer in which each individual Curse or Ruin has less of an effect on you average money density.  This is assuming that using trashing as a means to control Curses is minimal and that engine potential is low anyways.

Here are a few sample games that I have played recently using Masterpiece to great effect.

This game shows the power of Masterpiece to overcome cursing from Witch.

Hunting Grounds/Masterpiece has 18 Silver after turn 8!

This game shows province buying power in a Swindler/IGG game.

In a game with Pirate ship and no reliable +Coin, Masterpiece easily overwhelms the attack.

[Awaclus]

The first paragraph is not emphasized enough.  That first Gold is extremely helpful.  Subsequent $6 should most often be Masterpiece buys.

I almost agree with this now. Early on, Gold is superior, and as the game goes on, Masterpiece becomes better and better in comparison. However, I think that rather than buying 1 Gold and Masterpieces after that, you should buy Golds until you get your first big Masterpiece and Masterpieces after that, because the reason why the Golds are extremely helpful is that huge Masterpiece buy - you want to maximize the number of Golds before that, but after that, Golds aren't that useful any longer. Usually, this means getting 1-2 Golds in practice.

[Awaclus]

Actually, now that I rethink this, you should already buy a $6 MP when you think you're going to get a huge MP buy later before your next reshuffle.

[Awaclus]

Hermit's very nice with Masterpiece. First, you get to trash your Estates and gain some Silvers, then you get to draw a huge hand for a huge Masterpiece buy.
