Debris Beetle

A Vehicle that drains: that pairing is the whole design idea here, and it changes what "crew" is asking of you. Most Vehicles reward attacking, since the crewed creature stays behind while the wall of stats swings in. This one front-loads the payoff onto the enter trigger, so the six-life swing lands the moment you get it onto the battlefield, before a single attack step and independent of whether it ever connects. Crew 2 is the low tax that makes that immediate; two power's worth of tapped bodies, and you have flipped six life and a 6/6 trampler onto the board in the same beat. The Vehicle framing matters because a Vehicle is not a creature until crewed, which means it dodges the sorcery-speed sweepers and creature-targeted removal that a comparable enters-the-battlefield drain body would eat: park it uncrewed as an artifact, drain resolved and banked, and it costs an opponent a real removal spell to answer a threat that already did its damage. The trample is the closer, ensuring the 6/6 does not stall out behind a chump. It reads as a beatdown card and functions as a reach engine wearing a body, the kind of Golgari midrange piece that wants the life total to matter on both ends of the table.
