Komainu Battle Armor

Goad is a strange keyword to weld onto Equipment, because the mechanic exists to redirect aggression that other people would otherwise point at you: goaded creatures must attack, and must attack someone other than the player who provoked them. Bolt that onto gear that keeps connecting with players, and each hit becomes a provocation, conscripting the damaged opponent's board to swing into someone other than you. Reconfigure keeps the engine mobile: it can attack under its own power with menace, then attach at sorcery speed to whichever creature is likeliest to land damage, pumping that attacker and stapling the goad trigger to it. Menace on both the Equipment and its wearer is not redundant so much as insurance, keeping the carrier hard to chump-block on exactly the swings that fire the goad clause. This is a control tool wearing an aggressive costume: you are not assembling a bigger threat so much as manufacturing a war you would rather your opponents fought among themselves. That is a specific enough job that the card lives almost entirely in one place, where several opponents make goad worth the mana and the four-mana reconfigure cost is a real tax you pay to keep the provocation attached to the right body turn after turn.
