Dead-Iron Sledge

Equipment as threat-of-removal rather than a stat boost: strap this onto a creature and the combat math inverts entirely, because any block or block-against becomes a mutual execution. The mechanic weaponizes the opponent's own combat decisions. A blocker that would happily trade up gets erased alongside whatever it stopped, and an aggressor who walks into the equipped creature does the same. The destruction is symmetric and unconditional, so the equipped creature is expendable by design: you are spending a cheap body to guarantee the death of something bigger, then equipping again. Pair it with a recursive or low-value creature and it becomes a repeatable assassination engine, where the only tax on killing through combat is the equip itself. The catch is that the kill fires only through combat, so it never touches a creature content to sit back, and the opponent often gets to choose which of their creatures, if any, walks into it. The era it came from leaned hard into Equipment as a new dimension of artifact design, and this is the corner of that space that treats a weapon not as a buff but as a poison pill: anyone who touches the wielder dies, and so does the wielder, every time, no exceptions.
