The kicker is the entire pivot here, and the choice happens up front: as you cast the spell you decide whether you are buying a bare 2/1 with haste or a 2/1 with haste that wrecks a land on the way in. Unkicked, the body is a weak rate, a one-toughness attacker that needs a clear or favorable board to do its work and gets traded away against anything that blocks it. Pay the extra red and the same card folds a Stone Rain into the package, blowing up a nonbasic while still swinging that turn. That dual-mode design solves an old problem with how land destruction should be priced: rather than handing you a creature and a Stone Rain stapled together at a fixed cost, it lets the opposing manabase decide whether the disruption is worth paying for. The destroy clause is deliberately narrow, hitting only nonbasics, so it targets dual lands, creature-lands, and utility lands that cost something to replace and ignores basics entirely; that restraint keeps it a tempo exchange rather than a denial engine. Haste matters to both halves: the unkicked clock attacks immediately, and the kicked land destruction never sits as a sorcery-speed liability the way a dedicated land-kill spell would. One slot, two jobs, and you commit to one of them at the moment you announce the spell.
