perhaps make it if stock < 1 then instant victory instead of 10. that would be interesting especially when the enemy keeps ur resources down and his victory seems close
Getting 0 stock on your turn is extremely difficult to do without your opponent's help, and surely he wouldn't be stupid enough to play too many resource draining cards if he saw you had this in your hand. It would be possible with cards like difficult times, new era, all-elemental attack, plague, and militia, but still, it seems like it would be quite tricky.
