Subterranean Tremors

A scaling X-damage sweeper with two thresholds stacked on top of the base effect, built so the same spell answers three different board states depending on how much mana you pour into it. At low X it reads as a ground-clearing wrath that spares fliers, the asymmetry red has long leaned on to break a stalled board while keeping its own evasive threats intact. Cross four damage and it folds artifact destruction into the same card, a clause that wrecks equipment, mana rocks, and artifact creatures alongside the bodies it was already killing. Push to eight or more and the spell stops being subtraction and becomes addition: you raze the field and walk away with an 8/8 that survives its own damage for the cleanest possible reason. The token isn't on the battlefield when the damage resolves; the destruction happens first, and the Lizard arrives last onto empty ground. The lineage is the all-creatures-burn line that runs back to Earthquake, the original X-damage spell that hit every creature without flying: this one inherits that template and keeps spending past it, layering an Armageddon-for-artifacts and a haymaker onto a card that older designs left as pure removal. The cost of all that range is the cost every X spell pays: it does nothing cheaply, and both thresholds reward a deck that can assemble a critical mass of mana before it commits, escalating from spot answer to total reset to game-ender on a single card.
