Its not unreasonable to think you might just draw twenty cards, right there, and if your deck contains a very unusual amount of mana, you might not be far from drawing your whole deck (especially if youve got a couple of Dakmor Salvages somewhere in the mix, making it completely deterministic that you mill your deck, fill the battlefield, and set up some graveyard kill)
I suppose it is a little too slow to keep up with the current, hyper-aggro metagame but Domain and Mono-White Tokens both take advantage of the sweeper to maintain control in a game
MTG sets also have a buy-a-box promo card nowadays, which is usually a mythic rare
