Mistcaller Amphibian

Leap 1 (Whenever this creature enters the battlefield
or attacks, you may exile the top card of your library.
If you do, put a +1/+1 counter on this creature for
each land card exiled this way.)
At the beginning of your end step, if a land card
was exiled this turn, you may put that card onto
the battlefield under your control.
Master of mist and moisture, the Mistcaller
Amphibian is weaving its mastery.
