Consecrate Land

Targeted land destruction was the threat this aura was built to answer, at a time when Stone Rain, Sinkhole, and the Strip Mine effects loomed over every competitive deck: for one white mana, on a permanent that sticks around, your most important land became immune to being destroyed. The design discipline is in the seams. The aura grants indestructible to the land itself, which neutralizes destroy effects but leaves the land exposed to bounce, exile, and the various "sacrifice a land" clauses that came later. The "can't be enchanted by other Auras" rider is the self-protective half: without it, an opponent could simply layer their own aura on top to interact, and the card would fold to its own type. White's color-pie claim on protection-of-permanents is staked out here in miniature, years before hexproof or shroud existed as keywords, using the only tool Alpha had: an aura that buys a single permanent immunity to a narrow class of removal. The card reads as quaint now because the threat it was designed against (cheap, unconditional land destruction) was largely priced out of Standard-legal sets by the late 1990s. The card survives as a fossil of early design logic: a one-mana answer, in the color that would later own the "protect your stuff" axis, written before the vocabulary for any of it existed.
