Athena, Goddess of Wisdom

Partner with Gods and Demigods
Indestructible
When Athena enters the battlefield, look at the top three cards of target player's library, exile one of
them face down, and put the rest on the bottom
of the library in any order. You may look at and
cast the exiled card for as long as it remains exiled,
and you may spend mana as though it were mana
of any type to cast that spell.
{2}{w}{w/u}: You gain 3 life and draw a card.
