Steel Overseer

Every artifact-aggro engine before it cared about quantity: more cheap robots, more triggers, more reach off the top. This one cares about scaling, and it scales geometrically rather than additively. The first tap is unremarkable, a 1/1 nudging itself and its friends up a notch; the second is a snowball; the third typically ends games, because the counters land on every artifact creature you control at once and the threat compounds every turn it survives. That tap symbol is the whole tension. It contributes nothing the turn it lands, asks to live through a removal-heavy stretch, and rewards a board you have already committed rather than one you are still assembling. The body is a liability priced into the deal: a 1/1 that wants protection, slotted into builds that flood the table with disposable robots and then make all of them lethal in lockstep. Where most go-wide lords grant a static anthem that vanishes the moment they die, this one banks permanent growth. Kill it the turn after it has activated and the counters it already distributed stay on the board, locked in. That asymmetry, a temporary investment buying permanent stats, is why it has anchored go-wide artifact decks for as long as the archetype has existed: a removal target whose work survives its own death.
