Scarecrone

Two abilities sharing one body, each pointing at a different part of the artifact-creature pile. The first turns any Scarecrow you control (itself included, in a pinch) into a card, which makes it a sacrifice outlet and a card-advantage engine wearing the same coat. The second is the one that does the heavy lifting: a repeatable, no-restriction reanimation valve for artifact creatures specifically, returning them straight to the battlefield rather than to hand. That second clause is what gives this card its long shelf life. Artifact creatures span every color and every era, from mana rocks that happen to have a body to expensive bombs with enters-the-battlefield triggers, and a tap-plus-four to recur any of them from the yard is the kind of engine that ages well as the card pool grows. The 1/2 frame and the modest activation costs are the brakes: the reanimation is gated behind a tap, so you get one loop a turn, and feeding the draw outlet costs you Scarecrows you may not have to spare. The design's quiet cleverness is that the two abilities can chain into one another. Sacrifice a Scarecrow to draw, then spend the second ability to return that same Scarecrow from the graveyard to the battlefield: the permanent that fueled your card draw becomes the recursion target, and the loop refills itself. It is built less as a finisher than as the gearbox a graveyard-artifact deck rotates around.
