Animated Hauberk

Idle {4}{u}{u} (If you cast this card for its idle cost, it enters the battlefield as an Equipment attached to a creature of your choice as it resolves. It becomes a creature again if it's not attached to a creature.)
Hexproof
Equipped creature gets +2/+5 and has hexproof.
It's jarring when enemies watch a man they just killed seemingly get back up.
