Kerul, the Leapsage

Reach, Leap 3 (Whenever this creature enters the battlefield or attacks, you may exile the top 3 cards
of your library. If you do, put a +1/+1 counter on this creature for each land card exiled this way.)
You may play an additional land on each of your
turns and you may play land cards you own from
exile.
"With each leap, Kerul finds new realms to explore, harnessing the untapped power of the wilds."
