Someone once made the mistake of going hardcore Chapel deck against my Spy/Throne/Thief in a set without any +Coin. Halfway through the game he was drawing his whole deck every turn, but could only buy a single Copper each time, only to have it trashed immediately next turn.
I felt really bad, actually. But it was hilarious.
This kind of play can really cause havoc FtF. We did have one game like this where one player had 3 Provinces before anybody had anything. He lost the game to the player who ended up with 5 Provinces after me and another player hammered him with Thief plays.
This was a game between 3 friends who have been friends for a long time, and two guys who are roommates. It turned ugly and we all had to take a break afterwards.
We all agreed that such a play was legal. We also accepted that under the circumstances it was the only possible way to get back in the game. But it did create some ugly feelings since one of the players was eliminated without being eliminated.
