Scorch the Fields
A land-destruction spell welded to a tribal anti-aggro effect, and the join is the whole point: this was built for an era defined by the war between Humans and the things hunting them. Five mana to blow up a land is a famously poor rate on its own; Stone Rain did the same job for three a generation earlier, and nobody was paying two extra mana for the privilege. The pricing only makes sense once you read the rider as the reason the card exists. One damage to every Human is a deliberately narrow sweep, tuned to clear exactly the one-toughness aggressive bodies a Human-tribal deck floods the board with, while leaving everything else untouched. Both halves fire together every time, with no choice between them: this isn't a flexible answer you point at the most relevant threat, it's a fixed package that punishes a manabase and a creature type in the same breath. Against a deck that is neither Human-heavy nor stumbling on lands, it does close to nothing. The design belongs to a lineage of cards that pay for a weak primary effect with a hyper-specific secondary one, betting that a defined metagame will keep both clauses live at once. Strip the tribal context away and what remains is an overcosted Stone Rain; the gamble was that the context would never be stripped away.
