Well this can go for anyone but I've seen Seastan say this is his main hobby, his huge task of the-one-deck is done and so I thought why not suggest.
Is every quest in the game beatable with the minimum of purchase cards to enable the scenario?
Meaning 1 core plus the quest pack and any associated deluxe.
Eg: Say stewards fear. Can you build a deck to beat it with just 1xCore+heirs of numenor+ stewards fear
Etc
Very curious to see if it's doable
big big undertaking though
