Path of Discovery

Whenever a creature enters the battlefield under
your control, it explores. (Reveal the top card of
your library. Put that card into your hand if it's a
land. Otherwise, put a +1/+1 counter on the creature,
then put the card back or put it into your graveyard.)
Years ago, Mount Coronet use to be an active volcano
but a mysterious energy silenced the mountain. It now eternally slumbers while trainers explore it's cliffs.
