Hard-Fought Jungle

Hard-Fought Jungle enters the battlefield tapped
unless an opponent controls more lands than you.
When Hard-Fought Jungle enters the battlefield,
search your library for X target land cards or
creature cards with power 4 or more and exile
them, where X is the number of Forests you
control.
Whenever a Forest enters the battlefield under
your control, return a card exiled this way
to your hand.
