Gaea, Titan of Life's Touch

When Gaea enters the battlefield, sacrifice it
unless it escaped.
Whenever Gaea enters the battlefield or attacks,
search your library for a basic land card and put
it onto the battlefield. Shuffle. If Gaea escaped,
you gain 1 life for each land you control.
Escape—{w}{u}{b}{r}{g}, exile five other cards from
your graveyard. (You may cast this card from your
graveyard for its escape cost.)
