Armament of Nyx

The conditional written into this Aura is a wager on a single question: is the creature it's stuck to an enchantment, or isn't it? Land it on a creature that also carries the enchantment card type (a bestowed creature, a god, the rare enchantment-creature hybrid) and the Aura hands out double strike, an aggressive payoff for a typeline that happens to line up. Drop it anywhere else and the card inverts into a leash, preventing all damage the enchanted creature would deal. That two-faced split is the whole point: the same three mana either supercharges a creature you control or muzzles one your opponent does, and which mode you get depends entirely on the target's type. The prevention half is broader than a combat-only Pacifism but narrower in practice than it looks: it shuts off every source of damage the creature would deal, fight effects and tap-to-ping abilities included, yet leaves the body fully able to block and absorb attacks, so it pacifies rather than removes. It reads as a piece built for a self-contained enchantment-matters environment, an era that deliberately blurred the line between creature and enchantment so an Aura like this could plausibly find a friendly target worth the upside. Strip that context away and the punitive half is what survives: a sorcery-speed damage-prevention shackle that costs a mana more than the baseline and never gets to fire its better mode.
