Due Diligence

Auras have always fought the same structural war: they spend a card to buff one creature, and if that creature dies to removal, you have lost two cards to your opponent's one. This design chips away at that math by splitting its payoff across two bodies. The permanent buff lands on the enchanted creature, but the enters trigger fires on a second creature you control, handing out a temporary +2/+2 and vigilance that stays with that body no matter what happens to the Aura's host afterward. It does not save you from the classic Aura blowout (respond to the enchantment by killing its target and the spell fizzles before anything happens), but once it resolves cleanly, half its value has already migrated to a creature the opponent cannot answer by pointing removal at the enchanted one. The vigilance on both halves is the tell about what this is built for: a go-wide board wants to attack without surrendering the ground it stands on, and gifting two attackers who stay back on defense turns a single tap-out swing into a threat that also holds the fort. It is a small, honest piece of combat engineering rather than a bomb, trading the raw stat efficiency of a bigger enchantment for a hedge against the card disadvantage that has kept creature-enchanting out of serious decks for most of the game's history.
