Role Selection Deck Builder

In typical creative fashion, a new idea is now bouncing around my head, even though I haven't quite finished fleshing out the old ones.

Learning that my aunt is coming to visit from Canada in June, I figured this could be a chance to increase my game library by one. The problem comes from deciding which one, as well as finding one in stock, with Kickstarter projects posing some difficulties in that area.
I'm also assuming that with her limited luggage space, it will need to come in appropriate package and card games are good candidates. (If I can get a big box, I want to get my hand on Seasons.)

This lead me to think of all the card games I've played and enjoyed, as well as explore games I haven't played that could be good candidates.

As I enjoy role selection games as well as deck builders, I went on a search on Board Game Geek, and found Eminent Domain. While this seems like a fun game, it wasn't quite what I had in mind for this combo, which is why I am currently bouncing ideas in my head on how I would do it, which is mainly about having a bigger emphasis on the deck building aspect.

I also realize my 4X game idea had deck building.
