Shield Mate

A one-shot bodyguard, and a clean illustration of how toughness pumps trade differently than power pumps. The +0/+4 buys a creature out of one burn spell or one combat fold, but only by spending its own life: the Soldier sacrifices itself to do the saving. That makes it a single-use intervention rather than a repeatable shield, the kind of card that answers a specific threat (a damage-based removal spell, an unfavorable block) at the cost of a body you were never asking to win the game with. The design inverts the usual sacrifice-fodder logic: instead of feeding a death you profit from elsewhere, the death is the point and the protection is the payoff, with no second trigger to bank. It sits in the small family of one-drops whose entire value is held in reserve until the moment a fight breaks out, contributing nothing to the board until then. The toughness-only buff is the constraint that keeps it honest; it cannot turn a defender into a surprise threat, only keep something alive long enough to matter.
