Sphinx of Foresight
Most creatures with hidden-information text tuck away a keyword or a static bonus you unveil later. This one hides a decision about tempo, made before turn one, that most cards never let you make. Reveal it from your opening hand and you get scry 3 on your first upkeep, front-loading the smoothing when you need it most: a hand you cannot yet cast, a draw step you want to sculpt before the game develops. Crucially, revealing does not spend the card. You keep it, cast it later as a 4/4 flier, and collect the recurring scry 1 on every upkeep after. The opening-hand mode functions as a spell you never actually pay for, folded into a body you eventually will. That is the elegance: a seven-card hand with this in it plays richer than a seven-card hand without, because you know a burst of selection is coming before you have spent a single mana. The cost is information. The moment you reveal, your opponent knows a flier is on the way and can hold up a counter or sequence around it. Because scry sorts your library rather than growing your card count, neither the early reveal nor the later cast is degenerate; both trade in the same currency (card quality), paid on different schedules. The reveal clause simply lets you draw against that account before the game has begun.
