Malachi of Many Faces

Whenever another nontoken creature enters
the battlefield under your control, create a
white Aura enchantment token named Mask
attached to that creature. The token has enchant
permanent and totem armor.
Whenever a creature with an Aura attached to
it dies, you may draw a card and create a Gold
token. (It's an artifact with "Sacrifice this artifact:
Add one mana of any color.)
