Sea Kings' Blessing

Color-changing as an offensive enabler is a Legends-era design pocket the game has largely walked away from, and this is its purest instant-speed expression. It comes from a metagame where a creature's color was a live tactical variable, not a fixed attribute you stopped reading after deckbuilding. The most pointed application turns your attackers blue so that a defender with protection from their original color loses the prevention clause that mattered: a White Knight's protection from black does nothing once your black creatures are blue, and the damage that would have been zeroed out now lands. The design logic is pre-modern in a way that rewards attention: it predates the convention that combat tricks pump stats, and it treats "what color is this creature" as a knob you can turn at instant speed. Blue gets the card because blue is the color of changing what things are. The targeting is strictly creatures (never lands, never spells on the stack), which fences out the broader color-hate cards of the era: it cannot recolor your Swamps to dodge Karma, and it cannot touch a tax effect sitting on the stack. Within its lane it is precise, recoloring the bodies in combat and nothing else. What now reads as a curio was, in its moment, a one-mana answer to the protection clauses that defined Legends combat math.
