Shoreline Raider

Protection from Kavu may be the narrowest keyword Magic has ever shipped, and that narrowness is the entire point. The block this Merfolk debuted in was built around the Kavu: a swarm of ramping, beatdown lizards that defined the era's red-green aggression, and the design team handed out a handful of commons whose only function was to blank that one creature type for free. So this card exists to win exactly one contested race, in exactly one environment, and is functionally a vanilla 2/2 everywhere else. It is set-specific hate baked into a body rather than a sideboard slot, the kind of hyper-targeted answer that later designs would express through protection-from-color or protection-from-a-mechanic rather than protection-from-a-single-tribe. As a piece of Magic history it documents a moment when a creature type was so central to a block that Wizards thought it worth pre-loading the counterplay into the common slot. Outside that window, the printed keyword reads almost like a flavor joke: a Merfolk who simply cannot be touched by the dinosaurs crawling out of the deep. There is no portability here and no second life waiting in a later format; the card's meaning is locked to the moment it was printed and the creatures it was built to humiliate.
