Pin

A pin is a gamestate that occurs in two player games when one player forces the other to start each turn with a 0-card hand. In the classic pin, one player trashes his deck down down to just four or five cards: King's Court x 2 (or one and a village), Masquerade, Goons (or any other discard-to-3 attack). Every turn, the pinning player plays KC-KC-Goons-Masquerade, forcing the pinned player to discard down to three, then pass one card at a time to the pinner, who trashes them as they come in. The pinned player buys a copper, curse, or nothing with his 0-card hand, then lets the pinner trash his hand again. There are many other variants of the pin, a near-comprehensive list of which can be found somewhere on f.ds.
