Silent Skimmer

A 0/4 flier that does nothing in combat the way combat normally works: no power means no damage on the swing, but the attack trigger fires regardless and clips two off the defending player's life total whether or not anything stands in the way. The body is built entirely to survive long enough to keep attacking. Four toughness shrugs off most cheap removal, and ground blockers are irrelevant to a flier that does not care whether it connects, so the two-life clock keeps ticking turn after turn while the card itself sits as an awkward target: killing a 0/4 is rarely anyone's priority, which is exactly what lets it whittle a life total down uncontested. Devoid is the era's signature wrapper here, stripping the card of color while leaving its black color identity intact, since the in the cost still does that work. The mechanic suits the effect: a patient, attrition-based life-loss clock is the kind of slow inevitability black has always traded in. Note that the trigger only makes the defending player lose life; it returns nothing to you, so this is a one-directional drain on their total, not a swing in yours. The design is a clean demonstration that attack triggers are a separate axis from combat damage: this creature wants to be in the red zone every turn precisely because nothing it meets there matters to it.
