I do not agree with ket_the_jet. Ents are really good when know how to play them.
As sweet said, I suggest adding
Have Patience. Also, you may want to consider adding
Radagast because (I consider) ents are almost unstoppable when everything is set up. I have won several games against Ents who were destroying my shadow by running to site 9 with my fellowship. Maybe your starting fellowship could be improved a bit as Gil said, but it still looks OK like that. Another thing you can consider is cards adding damage bonus if you want to double-move easily or you could also add one of that Gandalf event that discard every minions if you move again. You may consider add 1 of that event that liberates sites with ents.
For your shadow, you should add some Enqueas against large fellowships like yours.
