Curator of Mysteries

A 4/4 flier for four mana with a cycling cost of a single blue is a body built to have two lives: cast it as a curve-topping threat early, or trade it for a fresh card whenever the matchup or the board has turned against it. The scry rider is what folds it into a deck built around cycling and looting, where each discarded or cycled card smooths the next draw, converting a graveyard-feeding shell into an incidental card-selection engine. The design discipline is in the word "another": the scry triggers when you cycle or discard some other card, never when you cycle Curator itself, so the payoff and the escape hatch never overlap. You either deploy it as a flier and reap scry from the rest of your discard, or you cash it in for a card and forgo the trigger. It belongs to a lineage of flexible win conditions that double as cantrips, the way a manland is both threat and resource, except the toggle here runs one direction only: once you cycle it, it is gone. The reward for committing to a cycling-and-discard build is a closer that costs nothing on the turns it sits idle in hand, because on those turns it is simply a spare card waiting to become a draw.
