Season of Flourishing

You may look at the top card of your library
(You may do this at any time.)
You may play the top card of your library if it's
a land card.
At the beginning of your end step, if you control
eight or more lands, sacrifice Season of
Flourishing, search your library for a green
creature card with converted mana cost equal to
or less than the number of lands you control and
put it onto the battlefield, then shuffle your
library.
