Breya, Etherium Shaper

The four-color splash and the fistful of Thopters are the most reductive reading of a design whose real statement is the conversion ratio. The 4/4 body arrives with two 1/1 flyers already on the battlefield, which means the sacrifice ability is funded the moment it lands: pay the two generic, feed those tokens to the clause, and you get a modal piece of a Lightning Helix on demand. Three damage to a player or planeswalker, a creature shrunk past most lethality lines, or a five-life cushion, repeatable every turn the artifacts keep coming. That is the engine the whole shell is built to feed, not the other way around. What makes this hold up as a build-around is that the modal sink wants fodder cheap to replace rather than fodder you were spending anyway: every Thopter generator, every token-maker, every small permanent that loops back becomes ammunition, while Treasures and Clues tend to consume themselves through their own activations before they reach this ability. The damage mode does the unsupervised closing work; a board of expendable artifacts plus two mana is a repeatable burn outlet that ends games without sending her into combat, since the ability carries no tap symbol and fires while she sits back on defense. She anchors an artifact-sacrifice lineage that earlier designs gestured at without the closing speed, and folding three modes onto one activated ability is what lets a single four-mana frame act as both value piston and finisher.
