Ultron's Auxiliary
A payoff that reads its own graveyard the way an aristocrats deck reads dying creatures, except the fuel here is metal. Every artifact that hits your yard, whether it dies on the battlefield or arrives via mill, discard, or a draw-and-pitch from anywhere else, grows this into a bigger threat. The second trigger clause carries the real weight: it does not care where the artifact was or how it left, only that it landed in the graveyard, so the counter ticks off self-mill, cheap sacrifice loops, and even artifacts you never intended to cast. Menace is the finisher rider, ensuring a body swollen by a dozen counters cannot be chump-blocked into irrelevance by a single token. What makes the design coherent is the direction of the accounting: artifact attrition, normally a resource you spend and mourn, becomes a running tally that only climbs. There is no ceiling and no reset; the creature never shrinks, so an artifact-dense deck treats every fabricated trinket, every Treasure cracked, every equipment lost to removal as a small deposit into a growing threat. The design serves grindy metalcraft-adjacent shells that want their graveyard interaction and their beatdown clock riding the same axis rather than competing for it.
