Rock Badger

Landwalk is the oldest evasion mechanic, and the bargain it strikes is that the keyword stays inert until the opponent happens to play the matching land. Mountainwalk is the least forgiving version of that deal. Against a white-blue control opponent this is a 3/3 for and nothing more, with no upside to salvage. Against a red opponent the evasion switches on, but that is exactly the matchup where a midrange beater earns the least, because the red mirror is decided by burn and tempo rather than by whether a Badger Beast gets chumped in combat. That inversion is the whole problem with color-pinned landwalk: the evasion lights up against the decks you least want to grind through the red zone with, and goes dark against the decks you most want to slip damage past. It is why this kind of conditional unblockability steadily ceded ground to flying, menace, and trample, which read the board state instead of the opponent's mana base. The flavor is at least candid about the catch: a badger that shrugs off rocky terrain, which is to say the very terrain its own color is built on. The body is plain by any era's standard, and the conditional evasion does nothing to lift it.
