Just buy the Rescue collection then. slowly build your collection up from the cheap to the expensive ones. That way your deck will improve over time and help you win more clintz to spend. that is how i built up my collection as a new player.
Personally i used budget Montana+Hugo, Rescue+Hugo when i started playing DTs. After a while i managed to save for the big Rescue cards and played DT with Rescue until i saved up for the Montana/Uppers DT deck. Once you have a solid DT deck, earning clintz/credits is not so hard
