Why Aragorn? For the threats? Why don't you use Treebeard instead? He's a strong companion and you can cycle him out of your deck very fast and he can discard a shadow condition. I don't see any need for Aragorn. And if you go over 5 comps, maybe you want to add Eowyn. I saw a variant of this deck long ago with a smeagol in it as well to cycle faster. Further it's a solid deck to play with.
