Go to your Collections - type in whatever your need, i.e. winding key, diagram, lantern, etc. and you will see the collections that reward them. Use this technique for whatever you may need. I just caution you to be aware of the fixers needed to combine. This also becomes a problem when you win/buy those fabulous "Chest" offers. Happened to me when I first started bought a bunch of Rare Chests, could assemble the collection except I didn't have the fixers to go with them and therefore could assemble for a long time. Hope that helps.
