Don't waste your cards on lousy odds. So, if you're not likely to win the roll and it's not essential to the adventure, save them for a better opportunity. It's normally a good idea to split the party at first. It lets you search through locations faster. Once you've narrowed down where the villain is, you can join up for some much-needed healing and mutual support. Cards you can use by reveal or recharge are much more valuable than those which must be banished or buried. They're to be favored when building your decks, even if they look less powerful.
