Wreck Remover

Colorless graveyard hate is a specific design problem: the color pie hands most exile-a-card-from-a-graveyard effects to white and green, so an artifact that does the same job has to justify why it belongs on a Construct instead of a spell. The answer here is repetition. The exile clause fires when the creature arrives and fires again on every attack, so a 3/4 body becomes a recurring drain on an opponent's recursion plan, chipping away turn after turn instead of resolving once and leaving. The catch is that "up to one" ceiling: this is not a graveyard-emptying sweeper, it is a slow bleed that clips a single card per trigger, so it wants a game long enough to keep swinging. The life gain is incidental padding, not the point. What makes the slot flexible is the floor underneath the ceiling: cycling gives the card an exit ramp for the matchups where nobody has a graveyard worth attacking, so the same piece that answers a reanimator or delve shell can be pitched for a fresh card when the effect is dead. That is the accommodation colorless removal has learned to make in the modern era: a body good enough to matter when the effect is live, and a discard-for-a-draw clause so the card is never a total blank when it is not.
