Benjamin, Aura-Binder

Hexproof
{w}{g}: Put a Bind counter on an enchantment you
control. Enchantments with bind counters
become equipment artifacts with 'Equip: {w}{u}{g}'. If it was an aura, benefits it would convey
to an enchanted creature are conveyed to
equipped creature instead. If it was not an aura,
it gains 'Equipped creature gets +X/+X, where
X is this artifact's mana value.'
