firstly do not burn your cards.....every solo player has felt like this. when the game first came out some did even leave the game, but if they had stuck with it they would see just how great solo play turns into
secondly....this game does get a lot of great cards for solo play in later packs, especially cycle 2. i will not say this is a 'buy to win' game because it isnt, but its worth remembering you only have the core set.
thirdly....the quests are indeed hard, infact core quest 3 is still considered unbeatable solo by all but the best decks.
now the decks...as you say you have tried deck building, and i would say keep doing this- the mono sphere decks arent developed enough to be strong in core set card pool.
i am never much good at recommending full deck lists, especially with a limited card pool, but there are a few good decks you can make..instead of trying to list a deck i will give the follow recommendations on cards/ combos
-test of will is still a must have in all decks. perhaps a weakness of the game, but it makes spirit an almost must have in solo play. so whatever spheres you chose, try spirit and test of will and hasty stroke. that way treacheries wont affect you so much
-hero choice is key, before card choice. i would say a good group is aragorn who gives you an extra quester for 1 resource, eowyn who is a power quester (but useless everywhere else) and perhaps beravor who is great all round. this is 3 spheres so waters down your deck a lot, so you may want to take one out to make 2 spheres. my favourite is lore/spirit, so instead of aragorn try perhaps denethor, and put unexpected courage on him to take away really bad cards from the top of the deck.
-try to get some good combos going, such as beravor or gleowine + protector of lorien. this is basically card draw + a way to use excess cards to boost defense or willpower. remember that protector of lorien and beravor have been errated.
tactics is powerful but in solo less so in core set. legolas is one of the best heroes though, as he gives progress as well as killing enemies. get two copies of the blade of gondolin on him for 4 progress per enemy killed.
hope this helps
