Slinking Giant
Wither and a self-imposed combat penalty share one card here, and the friction between them is the whole design. As an attacker swinging into open air, this is a clean 4/4 for four: the -3/-0 only fires when it blocks or becomes blocked, so unblocked it threatens a full four damage, and that threat is the point. It bluffs the defender into a block, then collapses to a 1/4 the moment combat is joined, delivering exactly one point of wither before the exchange resolves. The penalty reframes what the body is for. Wither is what makes that single point of combat damage matter: it lands a -1/-1 counter that does not wash off, so the lone hit chips an opposing creature permanently even as the Giant itself usually trades down or dies in the fight. So the card runs on a two-state logic. Outside the block, it is a four-power clock pressuring the opponent into trading or taking damage; inside the block, it is a small, durable body that absorbs an attacker, sticks a counter, and survives, or chumps into a larger board to leave a permanent mark behind. The result is a creature built for grinding attrition fights, where the threat of four damage does as much work as the wither it banks once the block finally comes, and a single counter accumulated across turns outweighs the body that delivers it.
