I'm a little surprised to see that you're not making use of more of the Prowl cards, there are lots of great options that are made cheaper by using the Prowl cost, and others that add some excellent effects for an additional expenditure. See
Knowledge Exploitation for an example of the former, and
Notorious Throng for an example of the latter. I think I would also suggest using
Stinkdrinker Bandit over
Earwig Squad to give all your Rogues a nice boost.
