Dwarven Blastminer

Land destruction usually arrives as a one-shot spell; this builds it into a repeatable engine that punishes manabases full of duals, fetches, and utility lands while leaving basics untouched. That restriction is the whole hostility of the design: pointed at a deck leaning on nonbasics it can keep blowing up a land every few turns, but aimed at a basic-heavy mana base it does nothing. Morph is what makes the threat credible. Cast face down, it hides behind the same uniform 2/2 shell as any other morph in the deck, so the opponent has no way to read whether the card sitting there is a beater, a trick, or the engine that will start dismantling their lands one at a time. Flipping it for reveals the prison-warden role mid-game, often the turn after they tap out on a key nonbasic. The body is irrelevant once unmasked: a 1/1 whose only job is to carry the tap ability. What it represents is a piece of color-pie reasoning that has aged into rarity. Red's land destruction has narrowed steadily over the years, and a creature that strangles a greedy mana base over the course of a game, rather than slamming the door with a single Sinkhole-style hit, is a flavor of attrition the game has largely abandoned. It rewards a manabase metagame that no longer reliably exists, which is precisely what makes it worth understanding.
