Hard-Fought Meadow

Hard-Fought Meadow enters the battlefield
tapped unless an opponent controls more lands
than you.
When Hard-Fought Meadow enters the battlefield, search your library for X target
creature cards with power 2 or less and exile
them, where X is the number of Plains you
control.
Whenever a Plains enters the battlefield under
your control, return a card exiled this way
to your hand.
