Spyglass Siren

Explore normally happens once, on entry: a fixed reward stapled to the enters-the-battlefield trigger, taken whether or not the moment is right. This flyer breaks that reward off its trigger and hands it to you as a Map token, a physical artifact you cash in later, on the turn a creature is finally worth improving or a hand is worth digging past. That detachment is the design's real move. The sorcery-speed restriction on the token keeps the flexibility from being total, and the sacrifice clause means the Map itself becomes fodder for whatever counts artifacts leaving, so the single card seeds three subthemes at once: an evasive body on the board now, an artifact for the counters, and a deferred explore held in reserve. The 1/1 is deliberately fragile. It chip-attacks, trades, and dies to almost anything, but the card has already banked its worth onto the Map before the creature is ever at risk, so losing the body costs nothing the account hasn't already settled. What makes it clean rather than merely stuffed is the discipline: neither half comes free, the timing gate is real, and the two effects run on different clocks. An immediate threat and a stored second act, priced so that neither is a giveaway.
