Dominion Black Market Promo

– Black Market allows you to Buy a card during the Action phase.
– You can use $ provided by other Action cards played earlier in the Action phase and you can also play Treasure cards from your hand to pay the cost of the bought card.
– The Treasure cards are played to the table in your play area, just as you would during the Buy phase.
– You may play more Treasure cards than are required for the purchase; the extra $ from Action cards and Treasure cards are available to use during your Buy phase.
– You may even play Treasure cards without Buying a card.
– You may not reuse $ already spent during a turn.
– A card bought during the Action phase does not count as a card bought in your Buy phase, so you do not need an Action card giving you +1 Buy to still buy a card during your normal Buy phase.
– To use the Black Market Kingdom card, you must create a Black Market deck before starting the game. The Black Market deck is made up of Kingdom cards that are not in the Supply of the current game. The players should agree before the game which cards will be used to create the Black Market deck (for example, you could agree to use one of every Kingdom card you own that is not a part of the Supply).
– It is recommended that the Black Market deck contain at least 15 Kingdom cards, with no duplicates.
– All players can see which cards are placed in the Black Market deck before the game begins.
– Take one of each selected Kingdom card, shuffle them together, and place the deck face down on the table where all players can reach it.
– This deck is not a Supply pile and if it is emptied, it does not count towards the end game conditions.
– If you play Black Market and the Black Market deck is empty, you cannot buy a card but you still get +$2.
– If you play Black Market and choose not to buy one of the three cards from the Black Market deck, you still get +$2.

Other clarifications (from wiki):

– Any setup instructions or “in games using this” rules that apply to cards in the Black Market deck are in effect, even if nobody ever gains (or even reveals) the relevant cards. For example, if Young Witch is in the Black Market deck, you add a Bane, and if Charlatan is there, Curses are Treasures for the whole game.
– It is not necessary to include every unused Kingdom card; you may decide how many cards to include in the Black Market deck, and which ones, in any way. In general, Donald X is a bit indifferent as to how the Black Market deck should be constructed specifically, especially given the complexities introduced to Kingdom card piles in more recent expansions.
– Dominion Online creates a deck of up to 60 cards (less if both players have a free account). It does not include cards with an obvious setup that would give away what’s in the Black Market deck, such as Tournament or Baker.
– On Dominion Online, the Black Market deck is shuffled after every card in it has been seen.
– For piles with differently named cards in them (e.g. Knights or split piles), only one of each can be added to the Black Market deck.
– Black Market does not give you an extra Buy phase; you are (usually) buying from the Black Market deck during your Action phase. So, for example, the cost of Peddler stays at $8, and cards you buy won’t count for Merchant Guild.
– You cannot pay off D while buying from the Black Market, and you cannot buy anything from the Black Market if you have D. You also cannot buy cards if it’s a Mission turn.
– Buying and gaining a card from from the Black Market will count for anything that cares about cards that you bought (e.g. Haggler or Swamp Hag).
– If gaining a card from the Black Market causes you to gain more cards (e.g. you gain a Border Village or a Stonemason), the cards you gain come – from the Supply, and you can’t gain one of the other revealed cards.
– The Black Market deck is not considered a “pile”, and cards from the Black Market deck don’t have a pile. This has several implications. You cannot exchange cards that come from the Black Market deck (e.g. with Trader or Changeling, or if they are Travellers or Vampire). Cards from the Black Market deck cannot be returned to a pile or the Supply (with e.g. Way of the Horse or Swap), meaning that those cards will stay where they were. The Gathering cards will not accumulate  VP anywhere.
