Land Searching

Whenever a creature or land enter the
battlefield, search your library for a land
and put it into hand, then shuffle your library.
Whenever creature leaves the battlefield,
put a 1/1 green Saproling creature token
onto the battlefield tapped.
"While humans search to claim new land, we strive
to live long enough to find a habitable shelter."
