Piledriving

Piledriving occurs when one player buys or gains all the cards in a supply pile. Piledriving is more likely to happen when only one player is persuing a certain card and wants as many possible copies of the card in their deck, or a player executes a megaturn such as King's Court-King's Court-Bridge-Bridge-Bridge to deplete the Province or Colony pile before any other player can get even one.
