Precognition Field

Future Sight gave a whole deck this ability for free, and the lesson it taught was that casting from the top of your library is one of the strongest things a permanent can do: it converts every draw step into a card you have already seen and turns library order into a resource you can manipulate. This narrows that idea down to instants and sorceries, which is a sensible tightening rather than a weakening: spell-dense control and combo decks live and die by their next card, and seeing it (then playing it) collapses the variance those decks struggle with most. The two static lines work in tandem. Looking at the top card any time is the information half; casting your instants and sorceries from there is the payoff half. The exile activation is the steering wheel: when the top card is a land or a creature you cannot cast off the enchantment, you pay to dig past it, smoothing toward the next playable spell. That activation is also the reason the card does not simply read "draw extra cards" and stop. It costs real mana, so each look you fix is a tempo decision, not a free filter. The friction is built into the toll, not into the abilities themselves, which is why the effect feels so clean while still demanding you build around it: load the deck with cheap spells, accept that creatures sitting on top are dead weight until you pay to move them.
