Game research - 4x and card game mix

In last weeks I've been trying to figure out a good idea for my next game and I'd like to create a mix between 4x games and card games.
Imagine a game like civilization, where you have a lot of micro management.. and remove that micro management with cards players can play and order to explore a new zone or create a new colony.

paper prototype!

So I've created a little paper prototype and found fun and interesting! A looot work to do, bus seems promising!

I have build a little google module to get feedback from everyone, it requires only 5 minutes:
