Future Sight
Lending the card its name to an entire set says most of what matters: this is the effect Wizards thought interesting enough to build a future-themed expansion around. The function is pure information conversion. Your top card stops being a random draw and becomes a known quantity, which transforms every decision downstream: you sequence around what you can see, you crack fetches and shuffle effects to dig past dead cards, and you turn the library itself into a second hand you cast from. The cost is the steepest part of the design. Triple-blue on a five-mana enchantment that does nothing to the board demands a deck willing to pay full freight for raw card advantage, and the payoff is throttled to one revealed card at a time, so it never floods you the way a draw-three would. The real tension it resolves is between knowledge and tempo: you always know your next card, but you can only ever access one, which keeps a runaway engine honest without a sacrifice clause or a counter doing the work. That single-card window is also the engine's seam; pair it with anything that helps you clear cards faster off the top and the trickle becomes a stream. It is the rare card-advantage piece whose ceiling is set not by what it draws but by how fast you can clear what it shows you.
