Using assassins for expansion

[Ironhawk]

While this method does work, it should be noted that its really slow. You have to spend 1-2 turns assassinating (this assumes a group of assassins) and then another turn to move to the next province. So 2-3 turns per province if things go well. Whereas if you spent the money on troops you could buy mages instead and your troops can attack a new province every single turn.
