Scout's Warning

A flash enabler that replaces itself: the design problem it solves is the dead-card tax that grant-flash effects normally carry. A card whose only job is to let your next creature ambush a blocker or hold up an instant-speed play is a liability when you draw it at the wrong moment, since it does nothing on its own and you have spent a slot on a permission slip. The cantrip is what makes this version worth running: when the flash window does not materialize, you still trade the white mana for a fresh card and lose almost nothing. It also unlocks a specific timing trick, since the grant applies to your next creature played this turn, you can crack it on an opponent's end step, draw, and then deploy a finisher at instant speed when they have already committed to their turn. The narrow part is the single-creature limit and the same-turn clause; this is a setup spell for one ambush, not a standing flash engine. White rarely gets to play creatures on other people's turns, and the card hands the color a clean way to do it without committing to a body that already has flash printed on it.
