Goblin Settler

Stone Rain stapled to a body, which is the entire pitch: the same single-land destruction red has run since the earliest sets, except here the spell leaves a 1/1 behind and survives as a permanent you can reuse. That body is what gives the card its real ceiling. On its own it is a slow, four-mana way to set an opponent back one land, well behind the curve of plain land destruction. Attach a blink or recursion engine and the math changes entirely: every flicker is another land in the graveyard, and a creature that destroys a land on entry is exactly the kind of trigger those engines were built to abuse. The Goblin type line is incidental to the function but not to the play pattern, since the decks most interested in repeatable enters-the-battlefield value tend to find sacrifice fodder and reanimation targets cheaply. The design tension is honest: red gets land denial that recurs, but it pays for the privilege by stapling the effect to a fragile creature and a clunky rate, so the card only justifies its inclusion once the rest of the deck is doing the heavy lifting.
