Retriever Phoenix
Creature — Phoenix
Flying, haste
When this creature enters, if you cast it, learn. (You may reveal a Lesson card you own from outside the game and put it into your hand, or discard a card to draw a card.)
As long as this card is in your graveyard, if you would learn, you may instead return this card to the battlefield.
