The idea of this deck is quite simple.
-first of all, u need to creat a green land at side the opponent orb, or at one block of distance.
To help u in that task don't hesitate to creat uncolor lands, u'll transform them later in green land. You also play 3 "Wood elemental" to help u in that task.
-Second, don't show your "Voice of hunger" too soon (if u can), or the opponent will understand what you're gonna do. "Voice of hunger" destroy all your creatures at side of him and add their DEFENSE to his strength and def. Meaning that just a "living willow" will turn him into a 10/13 creature. I let u imagine what it can be with an "Oak father" with many green lands on the board.
-Third, once your big "Voice of hunger" is on the board, your opponent has only one turn to react, after that you'll play "Sagami grovecaller", teleport your "Voice of hunger" to the green land at side the opponent orb and game over.
Of course it's never as easy as i write it, but you play massive creatures, many of them have the taunt ability, and you play "feed the forest" which should help you with the faeria issues.
You also have a bit more mobility with the 3 "Sagami grovecaller".
