Renewing Spring

When Renewing Spring enters the battlefield,
you may put a land card from your hand onto
the battlefield. If you do, return a land card you
control from the battlefield to its owner's hand.
{2}{u}{g}: Untap up to two lands you control.
At the beginning of your end step, if you played
three or more lands this turn, search your library
for a card named Scorching Summer, reveal it,
put it into your hand, then shuffle your library.
