The trade is stated plainly in the first line: this comes in tapped, and the tempo you lose on turn one is bought back by a scry on arrival. That is the whole bargain of the scry-land cycle, and it favors the deck that does not need its mana to be untapped early. The scry is not just card selection: it is information that compounds with the rest of your manabase, smoothing a draw before you ever cast a spell, and it gives an otherwise inert land a reason to be the first thing you play when nothing else is happening. Compared to the painlands and the original dual lands, the cost here is paid up front in time rather than in life or in a narrow availability window, which makes these the fixing of choice for slower decks that can absorb the lost turn and would rather not bleed life into their own mana. The Azorius member of the cycle sits in the most natural color pair for that patience: white and blue have always been the colors most willing to spend a turn doing nothing in exchange for a better game two turns later, and a land that scries on the way in rewards exactly that disposition.
