Cavalier of Thorns
Oracle Text
Reach
When Cavalier of Thorns enters the battlefield, reveal the top five cards of your library. Put a land card from among them onto the battlefield and the rest into your graveyard.
When Cavalier of Thorns dies, you may exile it. If you do, put another target card from your graveyard to the top of your library.
Just wondering, why does this require the "another target card" text? Isn't it already exiled?
