But why would stacking work like that? For instance, if it says "reveal 4 cards from the top of your draw deck", you would set them aside and reveal them all at the same time, only THEN returning then to the top in the order they were in. Just because most people would play by revealing one after the other, it doesn't make it correct. In absence of an explanation to the act of stacking, but having the info that stacked cards are revealed, you should move the top card FACE DOWN, stack it and then flip it over so it's revealed. Of course, this is only my point of view, but I do read a lot about game rules in general.
