I really like the Silvan enter play - leave play mechanic, and, in my opinion, being a solo player, the best way to play with them is using two decks and play "2 headed", because you need some elements of each sphere to really use all it's potential.
My question is... what is in your oppinion, the best heroes combination to maximize synergies amongst Silvan cards? (Trying to fit as possible to the theme, using only Silvan or Noldor heroes)
I've seen some builds focusing on "powerful" heroes, such as Lore Glorfindel, Elrond, and Elladan-Elrohir, but, in my Point of view, the best way to improve the Silvans is with low-threat decks and Haldir, Hands upon the bow, Quick strike, feint, feigned voices... to kill enemies without having to defend.
With this in mind, my first deck has as heroes: Galadriel, Celeborn and Glorfindel (spirit), with an starting threat of 25, and the second one has: Haldir, Legolas and Mirlonde, with a threat of 24. The main weakness on this build are the siege quests, but on the other quests they are working quite well.
PD: I apologize for any error in my wording.
