Lithobraking

Two effects that rarely share a card meet on a single resolution: ramp on the front end, a symmetrical two-damage sweep on the back, bridged by an optional artifact sacrifice made while the spell resolves. Casting it always nets a Lander, so the floor is instant-speed fixing even if you stop there. The wrinkle is what you feed the damage. The Lander is the obvious fuel, but sacrificing it to power the trigger means you never crack it for a basic; the token that would have ramped you becomes the board wipe instead. Point a different artifact at the cost and you keep the Lander, get your land, and still clear the field, which is where the card is at its sharpest and where the resource math bites: the sweep costs no card, but it does cost an artifact you needed lying around. Two damage to each creature is a deliberately modest wrath, sized to punish a low-curve, go-wide start without threatening your own midsize bodies, so the ceiling is a tempo swing rather than a reset. Because it all happens at instant speed, the tightest line is holding it for a combat step: ramp plus a blocker-clearing or attacker-thinning sweep, both settled in the same window. The design lives entirely in that one branching decision on resolution, with the artifact cost drawing the line between developing your board and interacting with theirs.
