Observant Alseid

The oldest complaint about Auras is the free two-for-one: staple a buff onto a creature, watch the opponent kill the host in response, and you have traded a card for nothing. This nymph refuses that trade. Pay the enchantment premium to graft +2/+2 and vigilance onto a creature already in play, and if that creature dies, the buff does not evaporate: the enchantment unhooks and stands up as a 2/2 with vigilance of its own. The worst case is not a blowout, just a slightly overpriced body. That fail-safe is the whole reason the pricier line is worth taking, and it is why the keyword was invented. Vigilance appearing on both halves is the design's quiet argument about what kind of deck wants this: attach it to an attacker and the enchanted creature swings without tapping out, and should it fall, you are left holding a blocker for the crackback. The numbers are deliberately restrained. A 2/2 for three mana is filler, the bonus is modest for what the graft costs, and the rate never threatens to run away with a board on its own. The appeal is structural rather than statistical: it turns a fragile Aura into a creature that pays its own insurance, which is exactly the problem this whole class of card was built to solve.
