Honestly, it seems like a decent deck. The Free People's are strong, you have
Momentous Gathering to play your Ents (and Gandalf) without drawing them, Pippin and Merry will be using pipeweeds like they should. The only issue seems to be Frodo surviving, but you might enough companions that you don't need to worry about it.
Shadow side seems solid. You have enough wargs, you got a strength pump that will almost always be +4. I think, and anyone is free to disagree with this, drop the exert to wounds. If you could replace the
Scouting Orc's with more
Saruman, SoS's and
Feral Ride's, I think you would be sitting pretty.
