Explore folds a scry-and-grow into a single trigger, but the Map token detaches that exploration from the creature that made it: instead of exploring on entry, you bank the effect as an artifact and cash it in later, on a target of your choosing. That deferral is the whole design logic. The 2/2 flier is a serviceable evasive threat on its own, and the Map it makes on entry lets you decide when the growth happens and where it lands. A creature that explores on entry commits the payoff immediately; a creature that hands you a Map lets you hold the trigger until a combat step wants a 3/3 flier instead of a 2/2, or until a fresher creature is more deserving of the card advantage. Because the Map can only be cracked as a sorcery, this stays a tempo tool that plans a turn ahead rather than an instant-speed combat trick: you cannot ambush a blocker mid-combat, only set up the swing before it. Among the Map-makers, this is the one that puts the deferred explore on an evasive clock, an option that trades the immediacy of an on-entry explore for control over timing and target.
