Mukotai Soulripper

A four-power body for two mana looks like a bargain until you remember a Vehicle is inert on defense: it does nothing unless you spend creatures to crew it, and it sits idle every turn you can't or won't. That inertness is exactly what the black design leans into. The attack trigger turns the Vehicle into a sink for aristocrat-style leftovers: a token that already did its job, a creature about to die anyway, a spent artifact. Each sacrifice feeds a permanent +1/+1 counter and a menace grant, so a wide board of expendable bodies compresses into a single tall, hard-to-block attacker on a schedule you control. Crew 2 keeps the tap cost cheap enough that a couple of small creatures can animate it, and that is the pressure point: the crew requirement and the sacrifice trigger both draw from the same pool of disposable creatures. Tap something to make it swing, then decide whether that same something is worth eating for the counter. The card rewards a deck built to overrun with small permanents rather than protect them, and it asks each combat which of your pieces is worth more dead than attacking. It also dodges sorcery-speed removal on the turns it isn't crewed, since it isn't a creature at rest, which lets it survive board wipes that clear the fodder feeding it.
