Sasuke, the Last Uchiha

Sharingan—When Sasuke enters the battlefield,
look at target opponents hand.
Choose a nonland, noncreature card and exile it
with a Tomoe counter on it. As long as it is
exiled, you may copy it and cast the copy using
mana as though it were mana of any color.
You may look at the top card of your library at
any time.
