How about a 'potion of the week' or something to that effect each week. A different potion can be bought for gold every week (eg level 1500 doubler), and then that potion would become unobtainable except via AH or secure trade (ie, no new ones can be added to the game). Maybe limit to one purchase per player per day to prevent abuse and keep each potion's value high
