Dauthi Cutthroat

Shadow built an entire evasion subgame inside Tempest block: creatures with shadow live in their own parallel combat lane, untouchable by ground blockers and unable to touch anything without shadow themselves. The catch is that the same wall works both ways, and a board stalled into two separate combats needs a way to break the mirror. That is the design slot this fills. The activated ability is a repeatable, mana-and-tap kill spell that only fires within the shadow ecosystem, turning a 1/1 that almost nothing in a normal deck can interact with into the police force of its own evasive battlefield. It is a deliberately closed loop: the body is irrelevant outside a shadow shell, but inside one it answers the only creatures that could ever pressure you while contributing a clock of its own. The tap cost and single-target clause cap what the ability can do: it cannot sweep, and committing it to a kill means it is not attacking that turn. Read against the rest of the keyword's printings, it is the answer card the mechanic needed to keep shadow-on-shadow races from grinding into a permanent standoff, a removal spell whose entire targeting clause is the same self-contained world the creature already lives in.
