Elandor, Guardian of Growth

Creature spells with power 4 or greater cost {2} less to cast.

Whenever one or more creatures you control with power 4 or more deal combat damage to a player, you may search your library for a basic land card and put it onto the battlefield tapped. Then shuffle your library.

If two or more lands entered the battlefield under your control this turn, transform Elandor, Guardian of Growth.
