Sunken Glade

When you play Sunken Glade you may sacrifice another land. If you do, return Sunken Glade to
your hand at the end of turn.
Once during your turn you may reveal Sunken
Glade in your hand to put a green 1/1 Jungle
creature token into play. It has, "When this token enters play, if you control no lands put two more
green 1/1 Jungle creature tokens into play."
