I have actually had very little issue with resources. There are 4 Training grounds in the deck, and though there are not any units that generate resources, A Hero's Journey and In You Must Go make it pretty easy to get out what you need.

I've found the same to be true with my own deck, even before I added A Journey to Dagobah (which I'm starting to consider taking out again). Yoda's objective is a godsend.

I've toggled around a bit and decided to swap out A Journey to Dagobah with another Self-Preservation. The objective is just so great, and none of the cards are expensive, so I don't feel so bad for taking out the extra resources in Journey. I tend to use the Gotals for edge battles and the other cards as needed. I've had a lot of success with Soresu Training on Luke and Yoda, and Unwavering Resolve is a nice little trick to keep up one's sleeve.
