This deck is not creative at all, it is a crowdsourced SpLegolas/LeGimli deck.
My procedure was as follows -- I looked at decks using both Spirit Legolas and Leadership Gimli, prompted by them being two of the three possible mandatory heroes for January's solo league. Unsurprisingly, their most popular partner was Aragorn, and of those the most popular version was Lore Aragorn. It turns out that there are actually more of those decks at ringsdb than there are three hunters decks using the three core heroes, though I don't doubt that many new players have tried a core-only three hunters deck and given up in despair.
As usual, to turn my analysis into a deck, I used the median deck card count to apportion card slots to the most popular choices in each category, trying to use the most popular count for each individual card until I ran out of space. I also limited the cards to a single core set.
The end result should be a stereotypical Three Hunters Deck -- one that only includes cards that others have used the most (by percentage, not raw count) in their own decks with this lineup. If you want the typical Three Hunters experience, this may be a good fit -- and if it's not, don't blame me, blame the committee!
A subset of the decks employed very few allies for a true Three Hunters experience, so we have the rare event of Strider in a three-hero deck. With Wingfoot in place Aragorn can both quest and fight, while the abilities of Legolas and Gimli allow them both to quest, Gimli to defend, and Legolas to attack. Mirkwood Long-knife allows Legolas to boost both attack and willpower, while Dwarven Shield both bolsters Gimli's defense and helps him pay for Legolas-readying. Use the doomed events freely, secure in the ability of Aragorn to reset your threat.
