is there an easy way to tell? I bought a bundle but all the cards are just loose and mixed. I didnt want to look too intently before hand for the sake of spoilers.
The expansions are cards only, so all the other bits are from the base game. Unfortunately there is no expansion icon or anything in the cards, which is a huge oversight IMO, but you can sort the cards by the small number on the back. From that you should be able to figure out what cards go in what deck, and from the location names, hopefully what deck is from what set. The hardest ones will probably be the first 5-6 cards, that have the same backs in all the sets, so you're gonna have to read the fronts to figure out what story they match.
