Trade

I have 2-3 articles and an article series planned for the first half of this year. This one is about Trade, an event which seems to be somewhat ignored and shouldn't be. This is the only one planned broadly about a card or event as this type of article tends to fall rather low on the usefulness scale.



Silver is not a good card. Trade gives you Silver. Trade is a good event. Oops.

Letís try this again. Coppers and Estates are bad cards. Trade gets rid of them. Trade is a good event. Okay, thatís better.

And that is what it comes down to: Silver is better than other assorted garbage. Way better. Like worth $5 and a buy better to have 2 Silvers over 2 Otherassortedgarbages.

The Function

With $5 in play and one or two cards in hand, Trade gives you the option to replace those cards with Silver. This is good when those cards are worse than Silver for your deck, so Estates and Coppers and if your opponent is being nasty Curses and Ruins also. Now, while this is not pure deck thinning, it does significantly increase the power of one's deck without adding any additional cards, and so if it is to be done, should be done early and often.

While a comparison to any card will be imprecise, the most direct and relevant comparison is probably Jack of all Trades. Like Jack, Trade allows a person to both gain Silver and rid oneself of junk cards. Now, Trade costs $5 while Jack costs $4, and its advantages correspond to this price difference: as well as being able to trash Copper, buying Trade to trash even just one card puts the Silver in your deck a shuffle earlier than Jack would and does not leave an additional action card to draw - make it two cards in hand and it is a two shuffle advantage.

The Conditions

Since Silver is almost always better than the assorted garbage listed above, if Trade is the only way to get rid of that junk then it is more often than not the correct choice to Trade if one has two cards to turn into Silver. There will be some exceptions such as forgoing Trade for a power card such as Wharf which itself would lead to more effective Trade buys. In this case it will be rare that an engine which does not produce extra buys will be able to keep up with a Trade based money strategy (there is a notable and important exception that will be detailed more in a different article I have planned - presence of a discard attack).

If real (and strong) deck thinning is available then you need to decide if Silver is better than nothing, as Trade provides the former and whatever thinner the latter. In many engine strategies, this will not be the case until after the starting cards have already been cleared, although if before then, Trade is there to make that happen and is better than buying Silver or even Gold: if one Trades two junk cards one is adding between $2 and $4 of treasure payload while not increasing the size of oneís deck as buying one of these treasures would. In money strategies, on the other hand, Silver is nearly always better than nothing (same exception) and so Trade is most often preferable to investing in the thinner.

The Specialty

As alluded to above, Trade is one of the best money enablers around, and if Trade and no additional gains are present, one should think really hard before not pursuing a money strategy.

In the presence of draw, terminal or otherwise, Trade allows for lightning fast and extremely consistent money decks. Even a mediocre terminal draw money strategy such as Smithy can be improved to taking in 5 Provinces and 1 or 2 Duchies in 13 turns fairly consistently with no attacks coming in. A strong one such as Gear can make 6 Provinces in 12 turns a near certainty under the same conditions. Leaving some Copper in the deck is fine and looking to buy Trade 3 or 4 times is often ideal. While these cards usually lead to otherwise fast enough games that multi-gain engines should be able to overcome this, it is unlikely that the same could be said single-gain ones.

Additionally, such a deck will also be very resistant to junking attacks as one would might guess with the comparison to Jack. If better (and/or cheaper) draw is available than the junking attack, skipping the junking attack entirely to focus on speed while using a few additional Trade buys to turn the incoming junk into Silver when possible is likely to outrace the weaker or slower drawing junking player to Provinces. If the junking attack is the best draw, then you are buying it and just as with other draw, Trade to clean up the deck turns it into a force to be reckoned with.

Additional Thoughts
Here is a sample game (log) illustrating this speed with another strong money enabler, Courtyard. Here it takes me 12 turns to get to 5 Provinces and 1 Duchy.

I mention Trade specifically in the context of draw because this is the easiest and most consistent way to get to both $5 and 2 cards in hand; it is possible, if significantly more difficult, to reach these conditions otherwise, and Trade is a good option in these situations also for the same reasons as with draw, as can be seen in this game from Qvist (video).

For usefulness you should talk about trade+junker games where it is great. Without alt-vp trying to make engine work is usually futile as junker-trade bm will get decisive amount of vp before engine could trash down.

These junker bm should be relatively easy to simulate, I woulnt be surprised that witch-trade beats cultist bm.

There is exception with sea hag/young witch where getting 5 is hard and you want another draw card.

With any kind of draw, Trade is pretty good, especially terminal draw Big Money is crazy fast with Trade, but also Magpie BM for example.
But even without draw if your draws line up, Trade is a very strong option.

In my recent league match I had a game where Trade shined. Big Money was the only option and there wasn't even draw. But I had the most lucky draws ever.

T1 & 2: Silver
T3: Guide
T4-7: Trade
T8-12: Province

That means 5 Provinces in 12 turns on a board without draw.

T13: Wine Merchant
T14: Province
T15 & 16: Duchy

And then I had 50% VP, but I had the Province in hand. There's nothing my opponent could do.
I trashed all my starting cards but 2 of my Coppers. So even without draw if you have 2 Silvers and 1 Copper in hand, Trade is a reasonable option in Big Money as it upgrades 2 of your cards in one go.
You can watch the game here.

I have made a few additions to the article based on suggestions from sources here and not here, including using the game that Qvist has provided as an example (thank you!). It may go through one more revision as it stands depending on continued feedback.

Having said that, on to the next one.

the plain and simple point for money games is that 1 trade adds more payload to the deck than 1 gold - that is, it improves the average money density more (though you would still need some gold if it's BM with a handsize attack, obv).  and that $1 lower price point is a huge deal, particularly since trade is at its best with estates in hand.

I think an important question that the article should deal with is: In which situations do you want to Trade with only one junk card in hand?

I'd contemplate this in situations where I'm considering Silver for $5 cards like Royal Seal, Stash, and a 2nd/3rd copy of Relic (perhaps due to lack of capacity for more terminals). Upgrading an Estate or even a Copper into Silver could very well be stronger than Royal Seal and friends. Admittedly I don't have too much experience with Trade.

Trading one copper for silver is like buying a Peddler for $6.  Not so good.  Trading one estate/Curse for silver is like 2 Peddlers for $5, which is much better.

Nice article! I like the organization. Different, but covers the topic really well.
