Once the game has been sufficiently controlled, the deck can win through various routes like with Isochron Scepter and Dramatic Reversal or through a more traditional win condition like Talrand, Sky Summoner and a host of counterspells to protect it
This card is occasionally sideboardable in a format like Modern but is maindeckable in a format like Vintage
There were formats before that where the win conditions were even more apparent, and in those times, control was very easy to win with
