Sandworm

Land destruction with a haste body is a strange pairing on paper, and the strangeness is the point. Stone Rain and its descendants stall the opponent's development for a full turn's mana; the trade is tempo now for a body later. Bundling the effect onto a 5/4 that attacks the turn it lands folds both halves into one card: you set the opponent back a land and immediately start pressuring them with a clock they now have less mana to answer. The Rampant Growth clause attached to the target's controller is the wrinkle that keeps this from being pure Armageddon-style disruption. It softens the blow, letting the destroyed land's controller fetch a basic (tapped), so the effect reads less as color-screwing an opponent out of the game and more as denying the specific untapped land they were counting on this turn: their dual, their fetch, their utility land, swapped for a tapped basic that does nothing until next turn. That single-turn window is where the card lives. It is a tempo swing dressed as land destruction, and the haste is what turns the swing into damage rather than just a delay.
