If I have this enchantment out:
Greater Auramancy:
Other enchantments you control have shroud.
Enchanted creatures you control have shroud.
And I play a mind control enchantment on a creature:
Mind Control:
You control enchanted creature
What happens? Because the second the other creatures transfers over to my control it gains shroud which means its an illegal target for the mind control. Is there a faq for this?
