Graaz, Unstoppable Juggernaut

The name is the thesis: this is a lord for a creature type that has almost never had a critical mass to lord over. Juggernauts are a scattered, mostly colorless line of aggressive beaters, and no static effect had ever tried to weld them into an archetype. Graaz solves the population problem by fiat. Rather than buff the handful of printed Juggernauts, it overwrites every other creature you control into a 5/3 Juggernaut, so a board of anything (tokens, mana dorks, whatever survived to your eighth turn) becomes a uniform army that must attack and can't be chumped by Walls. The base-power-and-toughness rewrite is doing the heavy structural work here, and it cuts both ways: it turns your huge threats into 5/3s just as surely as it inflates your small ones, which is the tension a payoff this sweeping has to carry. The compulsory-attack clause is not a downside grafted on for flavor; it is the historical Juggernaut drawback (they have always been forced to swing) turned into a tribal identity and pushed onto the whole team. At eight mana for a 7/5 that dies to most removal the moment it lands, Graaz demands you have already committed to the plan before you cast it. It is less a curve-topper than a declaration: the anthem that finally gives an orphaned artifact tribe a captain to march behind.
