Titan of Regrowth

Trample
Whenever Titan of Regrowth enters the
battlefield or attacks, you may search your library
for up to two land cards, put them onto the
battlefield tapped, then shuffle your library.
Unearth {4}{g}{g} ( {4}{g}{g}: Return this card from your
graveyard to the battlefield. It gains haste. Exile it at
the beginning of the next end step or if it would leave
the battlefield. Unearth only as a sorcery.)
