- While this is in play, cards cost
1 Coin less, but not less than 0 Coin.
- This makes all cards cheaper (to a Minimum of 0 Coins) as long as it is in play. When it leaves play, it stops making cards cheaper. This applies to cards everywhere - cards in the Supply, cards in hand, cards in Decks. For example if you played
Highway, then Develop, trashing a Copper, you could gain an Estate, as Estate would cost 1 Coin while Copper would still cost 0 Coin. Using a card that lets you play a card several times (like Throne Room from Dominion) on Highway will not make cards cost 2 Coins less, as there is still only one copy of Highway in play. The bonus is cumulative; if you have three Highways in play, all cards cost 3 Coin less (to a minimum of 0 Coins).
