Avatar of the Woods

When Avatar of the Woods enters the battlefield, search your library for a creature card, put it
into your hand, then shuffle your library.
Whenever Avatar of the Woods attacks, look at
the top X cards of your library where X is you devotion to green. You may reveal a creature
card from among them and put it onto the battlefield tapped. (Each {g} in the mana costs of permanents you control counts toward your devotion
to green.)
