This is a deck I've been recently playing. Word of warning: I play mostly 2p games, so this deck is sort of a complementary deck to another one. As such, it works very well and it has some solid basis, but I don't think it would done well as solo.
As you can see, this deck relies heavily on Ents, so it's pretty slow to kick off. You don't want to loose any of your allies, because they cost you resorces AND one whole round. You want Quickbeam in your starting hand, ideally Treebeard too. Start collecting resources for reading your ents quickly.
Apart from that, it's just a little bit of elf support here and there, with some generic upgrades like Arod, Bow of the Galadhrim or Gondorian Shield. Apply it where/when necessary, according to situation.
Use Beravor's card draw as much as possible. Reuse Elrond to pay for Ents. Use Legolas to always kill something, so that his abilities trigger.
There's quite a lot of healing in here, so you should be fine in this regard. Overall, I'm very pleased with how it works, but it can certainlt be improved.
