Breya, Etherium Shaper sits at the center of an artifact-token swarm strategy that generates massive boards of Thopters, Servos, and other artifact creatures, then leverages their sheer numbers for value and pressure. The deck sacrifices artifacts to fuel Breya's damage and removal abilities, while effects that drain life whenever artifacts or creatures enter — like Pactdoll Terror and Impact Tremors — grind opponents down passively as tokens flood the battlefield. Treasure generation, artifact copying, and end-step untap effects keep the engine churning, with Haunt the Network and Scuttling Doom Engine serving as high-impact payoffs that convert artifact count and sacrifice into direct life loss.
