Adventures do get harder, and yes playing previous adventures can help. So can reading opponents cards and thinking about their weaknesses and building accordingly.
Previous adventures shouldn't be locked. The tutorial adventures disappear, and any adventure you unlock stays unlocked. If something became locked for you, you might send the devs an e-mail. However, if you mean previous adventures are exhausted, that's fine: they're still playable for brown chests and no experience, but wait until the next day, and they'll have nice chests and experience again (if your characters are close enough in level to the adventure to receive experience for it).
