Aegis of the Wilds

Whenever a Human creature you control attacks,
choose a non-Human creature type that hasn't been
chosen for Aegis of the Wilds. Create an Umbra
Armor enchantment token of the chosen type
attached to that creature. (It's a Kindred Aura enchantment with the chosen type, and it has Umbra
Armor. Its name is the chosen type followed by
"Umbra". For example, if "Dog" was chosen, create a Kindred Dog Aura enchantment with Umbra Armor
named "Dog Umbra".)
