I just realized that bishop had not been written about in some time, and that I was winning a lot with bishop. So I thought I'd share some insights. So here it is, let me know what you think:
Bishop is a high skill card. Sometimes it is a must buy card, and sometimes it is nearly useless, and it is often tricky to figure out if you should buy bishop, and when. Usually you DO want bishop: unless there are no villages and there are other desirable terminals, having a bishop mid/late game is almost always good, as it can give you control of the game. Cannibalizing a gold on the same turn as buying a province is often a winning move.
When don't you want bishop? I would say there are 3 rough cases:
- There are no villages, and there are stronger terminals, particularly terminal draw. Without extra cards and actions, you are less likely to be able to match up cards you want to trash with your bishop late-game, and the loss of economy hurts more. Also, getting rid of starting estates is very nice for the terminal draw player.
- Very fast, strong combos: If the game is about playing KC on bridges, or about playing multiple Goons together, a couple of extra points from Bishop probably won't matter, and you should just focus on comboing as quickly as possible, using your opponent's Bishop to your advantage.
- Cursers: if you are cursing an opponent, it is often counterproductive to give them the opportunity to trash those curses, especially early in the game. Exceptions to this do occur, as occasionally a game can get drawn out by curses to the point that its worth it to snag those extra VP from Bishop, eventually. Figuring out when to buy bishops in this case is quite subtle.
When do you want to buy bishop? Something counter-intuitive about bishop is that it is usually NOT an good early game trasher. Yes, I'll say it, opening with bishop is often bad (exceptions discussed below). Early game, bishop has two big things working against it: First, it only gives you $1, which can strongly hamper your ability to buy $5 and $6 cards. Second, [it gives your opponent just as much trashing as it gives you]. In fact, its a little better for your opponent, because they have 5 cards to choose from, and you only have 4. So the trashing is basically a wash, and you should not consider this an advantage. In other words, early game you can view bishop as a card that gives you only $1,+2VP when you draw it with an estate, and $0,+1VP when you draw it with a copper and no estate. This is TERRIBLE.
Bishop is still great, but it is a trasher you usually want to buy mid or late game. This is especially true in engine games, where the free trashing is even more useful to your opponent than it is to you. As the game, goes on, bishop's benefit to your opponent steadily decreases. I often buy it the first $4 I get after turn 3. As they buy more stuff, and perhaps trash cards, there is a greater chance they will have nothing to trash. And even trashing copper is painful sometime midgame, as it can keep you from buying critical cards. However, in engine games bishop is still useful to YOU in the midgame as a trasher, as you are drawing a large selection of cards. You can even trash junk that was useful early game, but is less useful now, like spice merchant or potion, and it will give you a very nice VP boost.
Obviously, bishop is good with the cards any trash-for-benifit card is: peddler, boarder village, haggler, hoard, these all shine with bishop, especially the first three, as they are easily incorporated into engine decks. Even less flashy ways of gaining cards such as ironworks or even talisman can be used to gain bishop fodder in a tight deck. Good dark ages combos include Rats and Market Square and Fortress. Specific interactions that HURT bishop include "draw up to X" cards. For example, Jack of All Trades can allow the jack player to trash a card, and still draw back up to 5, and likely draw an even better card than they started with.
What makes bishop unique, like goons, is that it can be used to gain a large amount of points without putting green into your deck. So while it can be used to canibalize your deck and get a last minute VP boost, it can also be used to create a very slim deck, often called the "Golden Deck". The cannonical golden deck is one gold, two silver, a bishop and a province. If you get to this point, you can trash a province and buy a province every turn, gaining 5 VP and drawing the same 5 card hand. This may not be as sexy as gaining 150 points with Goons, but in many games this is very strong. However, getting to the "golden deck" is slow in many games. The best start for the golden deck is bishop/chapel. There are other circumstances where you can get to the golden deck, but few others where I would force it. Just keep in mind that if your deck is getting really small, it is an option.
A few comments about the "golden deck". First is that once you go for it, you are basically stuck, so you better be sure its the strongest strategy. You are limited to 5 VP per turn, so strong engines that can buy multiple provinces a turn WILL likely beat you. Second is that there are often stronger variations on the golden deck, for example, I played a game where I bought border villages, gaining markets, while my opponent went for the canonical golden deck. While they got the early lead, at some point I was able to play two bishops per turn, trashing two BV/gold, and buy two replacements. I was able to avoid buying victory cards to stretch out the game, which is another strategy available with bishop that you want to take advantage of if you know you can win the long game. Fortress produces a super-powered alternate "golden deck", with four bishops and four fortresses in your deck, you can snag 12 VP per turn, every turn, with no luck involved, by repeatedly trashing the same fortress.
Works with:
- chapel
- border village, farmland
- gainers: hoard, market square, rats, ironworks, tunnel, etc
- fortress
- engines
Doesn't work with:
- opponents "draw to X" cards (Jack, Watchtower, Library)
- very strong combos which generate more VP (goons, bridge combos)
- opening (in many games)
- curses or ruins
- the golden deck does not work against strong engines
