Ok how about this.
You buy the border village during the black market phase. You have also previously to this turn obtained 2 curses and 2 duchies. You gain 10 IGG's from the Hagglers in play. At this point the haggelrs, duchies, IGG's and Curses are depleted. After the Black Market phase, you play 2 ambassadors returning 2 each of curses and duchies to the supply. Thus at the end of your turn only Hagglers and IGG's are depleted and the game continues.
It should also be noted this only works in 2P.
