Dewdrop Spy

The flash-and-flying body is the part that does the work; the enters-the-battlefield peek is the part that tells you what this design is actually for. A 2/2 with both evasion and the ability to ambush attackers is a fine blocker on its own, but the trigger reorients it: pairing this with the Faerie subtheme's library-manipulation tools turns a glance at the top card into something with teeth. Look at an opponent's top card and you have a target for the cantrip-style "spin" effects that bounce a known card back; look at your own and you set up the next draw. The trigger reads as pure information, but it was built to feed a tribe whose whole identity was rearranging the top of libraries at instant speed. On its body alone it is a competent evasive flash creature that holds up mana and threatens to trade up in combat. The peek is the part that asks for a deck around it: it does nothing in a vacuum and quietly enables a turn's worth of planning in the shell it was designed for. That gap between a serviceable Faerie beater and a piece of a library-control engine is the entire pitch of the card.
