Nature's Reaction

When Nature's Reaction enters the battlefield
and at the beginning of your upkeep, if an
opponent controls more lands than you, you may
search the top five cards of your library for up to
three basic land cards, reveal them, then put
them into your hand. Put the rest on the bottom
of your library in a random order.
If you were the last player to take your first turn
this game, you may play an additional land on
each of your turns.
