The math here is deliberately unglamorous, and that is the whole point. This is the floor of blue card selection: pay one mana at instant speed, smooth your next draw, and replace the spell itself with a fresh card. It does not generate advantage so much as preserve it, which is the trick to its longevity in a role flashier filtering keeps trying to muscle into. Scry 1 is the cleaner version of the job it has always done. Its earliest printing predated the keyword and spelled the effect out by hand ("look at the top card of your library, you may put it on the bottom, draw a card"), functionally the same spell it is now; only the templating changed, once scry gave Wizards a tidy word for the action. That continuity matters. Unlike Brainstorm, which sets cards back where you drew them and demands a shuffle to clear the deadweight, this commits to nothing blind: you see the card waiting for you, bottom it if it is useless, then draw something new. The decision is small and almost always correct, which is exactly what makes it the benchmark the heavier one-mana cantrips (Serum Visions, Sleight of Hand, Consider) get measured against. Spells like this do not win games. They keep a deck running smoothly enough that the cards that do win games arrive on schedule.
