Retriever Phoenix

“Flying, haste <br>When Retriever Phoenix enters the battlefield, if you cast it, learn. <em>(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.)</em> <br>As long as Retriever Phoenix is in your graveyard, if you would learn, you may instead return Retriever Phoenix to the battlefield.”
