Creature 14

Whenever another creature with power 2 or less
enters the battlefield under your control, you
may pay {2}. If you do, it studies and you gain 3
life. (Reveal the top two cards of your library. Put
one of them into exile and the other on the bottom of
your library. You may play the exiled card as long as
you control the creature that studied it.)
Teaching the younger ones is a tough, but really
satisfying task.
