Shadow side seems a bit scattered, especially with the lone troll in a swarming deck. I especially think that you should take out the troll chain which seems unnecessary and unlikely to be useful if you only have 1 troll in the whole deck anyway.
Also, the Uruk-hai are alright, but there are going to be better guys for the same cost that you can put in. For example, I really can't think of a reason to use
Cirith Ungol Patroller over
Orc Swordsman - so what the uruk is damage +1, he's the same cost and
Orc Swordsman has +1 strength with the potential for even more. If you're trying to swarm, why not consider some of those
![Sauron [Sauron]](https://lotrtcgdb.com/forums/Smileys/classic/sauron.png)
orcs which are designed for the purpose by helping you draw cards (like
Orc Insurgent)?
Other than that, I'd replace the uruk-hai with better Orcs, but otherwise looks decent.
