Here is an effective deck, 100% Noldor, to pass the Fords of Isen scenario and face its Time and Hand Size threshold mechanics.
The strategy is very simple: the heroes make us draw at a good pace at the start of phase 1, and we must strive to use or discard all the cards we have in hand before the end of the restoration phase and the end of the round, and even ideally before the staging step.
The deck is constructed in such a way that there is no "over-drawing" during the turn, so as not to trigger the Forced effects of Dunlendings enemies. I add Elven-light for having 3 more cards to discard and for staying in the elven theme, but I do not use its action. Furthermore, I have ruled out expensive or circumstantial cards (A Test of Will, Hasty Stroke, location control Events, etc.). Thanks to the pooling of resources of the heroes of the energy sphere, and the numerous discard options, I most often have 0 or 1 card in hand and I win quite easily.
The card to favor in first hand is the threat reducer Elrond's Counsel. It gives us more time to get set up and provides a very useful bonus for the quest in the first round. Elven Jeweler is a nice ally to have early too.
Nicely done! This is definitely an excellent way to counter the schemes of the Dunlendings. If you are looking to further optimize it, might I suggest replacing a few copies of your unique allies (Elladan, Elrohir, and Glorfindel) with Narya, Protector of Lórien, Song of Healing, and perhaps Will of the West? That would give you a few more options to get cards out of your hand in exchange for helpful effects.
Overall though, this looks like a fun and solid deck :).
