Drossclaw

Living weapon solved a specific problem the first time it appeared: an Equipment that does nothing until you find a creature is a dead card, so the mechanic staples a disposable body to it and lets the whole package function as a creature until something better comes along. This design leans hard into that self-sufficiency by making the Germ itself a clock. The +1/+1 turns the 0/0 token into a 1/1 that can swing on its own, and every attack costs each opponent a point of life, so the Equipment is a repeatable pressure engine before it ever attaches to a real threat. When you do move it onto a bigger creature, the life-loss trigger scales in relevance rather than magnitude: it fires on the declaration of an attack, not on damage dealt, so it does not care whether the equipped creature connects or gets chumped. That decoupling from combat math is the quietly aggressive part of the design; blocking the attacker stops the beatdown but not the bleed. The equip cost is high enough that the card wants to live as a Germ for a stretch rather than shuttle around the board, which is the balancing pressure on an effect that would otherwise be a free table-punishing engine on a two-mana artifact.
