This is my solo deck. Ive done around 15 different quests with success, without changing anything from quest to quest.. It's a very tight deck with very little that can be taken out. It has everything a whole group of friends need in one deck.
We have 2 bilbo with only one pipe for more reshuffle when we have a bad vilya target. Plenty of resource gen with arwen plenty of card draw through Expert Treasure-hunter. A little over the top on threat management with Elrond's Counsel for early on (as we have high starting and pull almost everything out of staging first round) and The Galadhrim's Greeting for when we cycle through the deck. And dont forget Elfhelm.
Plenty of action advantage in the way of Unexpected Courage/Shadowfax combo'd with Narya. We have the two Warden of Healing with Elrond to make sure our first round can be recovered by the usual undefended attacks unless you get a vilya in the starting hand. We have a decent army of questers, attackers, and gimli is a star for questing and defending.
Arwens recycling and hand management with daeron, elf light, steed has helped so much. Dont forget location control with steed and trackers!
I think this is MY personel best take on a decent solo deck with the cards i own. If anyone has some suggestions then i would be glad to hear it. But do remember, from experience in quests i have adjusted it to a tight deck where i can rely on the next draw to help everytime with no meh draws.
