Aurvaeus, Nyx Favored

Eminence - As long as Aurvaeus, Nyx
Favored is in the command zone or on the battlefield, enchantment creatures you control get +1/+1.
When Aurvaeus, Nyx Favored enters the battlefield, exile each creature you control
with bestow, then return those cards to the battlefield as enchantment auras attached
to this creature.
