Darksteel Plate

Indestructible was a keyword built for two readings, and this Equipment is the cleanest expression of the second one. Most cards that grant the word play defense: they want a creature to survive a wrath, eat a removal spell, brawl into a larger blocker and come back. This grants it permanently and detachably, so the equipped body stops caring about damage, destruction, and the entire family of "destroy target creature" effects at once. What that buys is not a bigger threat but an immovable one. The friction is deliberate: it does nothing to a tapped-out board on its own, it costs to move, and the wide gap between the answers it shuts off (combat, burn, "destroy target creature") and the answers it leaves open (exile, bounce, "-X/-X," sacrifice, edicts, "can't block") is exactly where the card is balanced. A creature wearing this is not unkillable; it is immune to the specific verb that most of Magic's removal happens to use, and nothing more. The plate itself shares the keyword, which matters more than it looks: artifact removal that destroys cannot pry it off, so the protection persists through the same sweepers it was bought to survive. It is the durable, color-agnostic answer to a removal-heavy table, the piece you reach for when the problem is not that your threats are too small but that they keep dying to the same word.
