Seeker of Souls

When Seeker of Souls enters the battlefield, exile
all Auras and Equipment until Seeker of Souls
leaves the battlefield.
For as long as those cards remain exiled, you may
cast them and you may spend mana as though it
were mana of any color to cast them.
Creatures other than Seeker of Souls cannot be targeted by Auras or have Equipment attached to
them.
