Volcanic Strength

Pump auras carry the genre's defining liability: a creature wearing one dies to any removal and takes the whole investment with it, a two-for-one waiting to happen. The +2/+2 is fine but generic; the real argument is mountainwalk, an evasion grant that turns a stalled board into a clock the moment the opponent controls a Mountain. That conditional is the whole bargain. Landwalk is the oldest evasion in the game, a holdover from the early days when colors were meant to prey on one another, and its value swings violently with the table: against a Mountain it reads "can't be blocked," against anyone else it reads two mana for +2/+2 on an Aura, a rate nobody wants. The design honesty here is that it never pretends otherwise. It is a tuned answer to a specific color, built so a red deck has a tool against the red mirror and against green-red ramp builds that lean on Mountains. As color-pie expression it is clean: red rewards you for reading the opposing manabase and punishes the mirror. Cast unprompted, it almost never clears the bar that two-for-one risk sets.
