Wildfire Emissary

A 2/4 body that most white removal cannot touch and white blockers cannot profitably trade with, sold as the floor of a creature whose firebreathing turns the toughness into an offensive clock. The protection-from-white slant is the whole design: against a color built around efficient creatures and clean removal, an Efreet that ignores both becomes a recurring threat rather than a one-and-done attacker. The firebreathing ability is what converts that resilience into pressure; left unchecked, the 2/4 grows into whatever the red mana allows, and white's targeted answers can't bite. It reads as a sideboard-style hoser stapled onto a maindeckable body, a common shape in the era when protection was red and green's preferred tool against white control rather than a niche keyword. The toughness matters as much as the protection: four points means it survives most non-white removal too, so the body holds its ground in matchups where the protection clause is dead. Nothing fancy in the construction, and that is the point; it is a creature designed to be a problem specifically for one color, with enough stat line and reach to remain a body everywhere else.
